Autor(es): Ballerini, Luisina Abstract: In Argentina, commercial floriculture began in Buenos Aires with the production of potted plants by Japanese and German immigrants at the beginning of the 20th century. Later, in the 1930s, production expanded to cut flowers. It was the most developed in Latin America until the 1970s, when political issues and poor management limited the growth of national floriculture. The economic climate of the 1990s then favored the introduction of new technologies for production, as well as the introduction of new varieties of ornamental plants and commercial substrates (Morisigue et al., 2012). The ornamental plant market is characterized by a very abundant supply of species and varieties, but in Argentina, despite nearly a century of production and a wide diversity of climates, commercial production is poorly diversified (Morisigue et al., 2012). In Patagonia, floriculture is a recent activity, with producers and investors interested in meeting market demand. There are approximately eighty producers of bulbs, cut flowers, and dried flowers, as well as nurseries and potted plant producers, dedicated to this task. In some locations (mainly tourist destinations), growth and development, accompanied by landscaping projects in both private gardens and public green spaces, are generating an increase in demand for ornamental plants (Mazzoni et al., 2008). In Northern Patagonia, the Tierra Baldía nursery is a renowned ornamental plant producer in the region. With facilities in the towns of El Bolsón and El Hoyo, it carries out part of the production and retail sales, but also supplies retail nurseries in several Patagonian provinces. 2025-10-03T00:00:00Z http://rid.unrn.edu.ar:8080/handle/20.500.12049/13543 Título: Evaluación del cultivo de seis variedades de Lilium en San Carlos de Bariloche Autor(es): de Urquiza, Silvia Abstract: Floriculture is the horticultural discipline that refers to the systematic cultivation of flowers and ornamental plants. Specifically, foliage and cut flowers, garden seedlings, foliage plants and potted flowers, bulbs, and seeds. As a commercial activity, it began to gain importance in the mid-20th century, and its high profitability has led many countries to invest in its production. It is a competitive and sustainable activity, and Argentina has great potential given its agroclimatic, geographical, and technological advantages. However, growth in the domestic market is slow, and its presence in the export market is scarce. Flower consumption has an aesthetic and emotional motivation because it benefits our lives by providing beauty and well-being (Morisigue et al., 2012). In Argentina, bulb production was almost nonexistent until 2001 due to the convenience of importing from Holland, as was the trade in cut flowers of this species. In 2002, bulb imports fell sharply due to the unfavorable exchange rate, which significantly increased flower cultivation costs. Considering the varied requirements of the different hybrids and the plasticity of the Lilium, its production is possible under different conditions. At this point, it is worth highlighting the advantages that Argentina has with a wide variety of environments and soil and climate conditions, which, together with the existing infrastructure, would facilitate the commercial production of Lilium bulbs (Facchinetti and Marinangeli, 2008). Lilium is positioned as the main cut flower from bulbs and the fourth most popular after chrysanthemums, carnations, and roses. Its flowers are widely accepted by consumers and highly valued in the market. According to Scoponi (2014), economic research indicates that the cost of bulbs imported from the Netherlands represents between 75% and 80% of direct production costs. Considering the nonexistent production in Argentina and the availability of compatible soil and climate zones, it could be argued that Lilium bulb production represents a business opportunity for the sector. Along with the production of cut foliage and tropical flowers, it represents a possibility for diversification that would improve the local market, leading to medium-term export projects. In Chubut and Río Negro, there are artisanal bulb producers who have demonstrated suitability for fattening. However, these bulbs are not produced on a large scale in Argentina due to commercial, technological, health, and legal limitations. Bulb production requires paying breeders' fees and the use of specific inputs not approved in Argentina, such as herbicides. Furthermore, harvesters, planters, and post-harvest machinery (washers, sorters, and packers) are not manufactured in the country, so their importation entails a high initial investment.

Autor(es): Lasmartres, María Pilar Abstract: INTA develops and incorporates technologies that contribute to obtaining quality timber and non-timber products, improving the competitiveness of forestry through genetic improvement, conservation of forest species diversity, health protection, knowledge of the technological properties of products, and management, considering the environmental services provided by forests (Retrieved from: https://inta.gob.ar/forestales) The geographic context for the Area's work generally covers the Andean and pre-Andean regions, from northern Neuquén to south-central Chubut. This region contains approximately 3 million hectares of native forests, 80,000 hectares of afforestation, and more than 800,000 hectares suitable for forestry. This vast territory is characterized by great environmental heterogeneity and the occurrence of extreme events, especially its dry summers, which are the main limiting factor for forest production. The Ecological Genetics and Forest Improvement group focuses on population genetics, and its main lines of research include the genetic characterization of natural populations, studies of evolutionary processes, functional genomics, quantitative genetics, and genetic improvement. The species studied include the native Cordillera Cypress, Pellín Oak, Raulí, Lenga, Ñire, Pehuén, Coihue, and Criollo Willow, and the exotic Ponderosa Pine and Oregon Pine. 2025-09-17T00:00:00Z http://rid.unrn.edu.ar:8080/handle/20.500.12049/13430 Título: Reproducción y cultivo de plantas nativas de la Patagonia para la restauración: una experiencia de trabajo en el vivero del Jardín Botánico de Isla Victoria (2012-2020). Autor(es): Valenzuela, Gabriela Belén Abstract: This document describes a pre-professional internship in the multiplication and cultivation of native species, conducted during a work experience period from 2012 to 2020 at the "Ing. Agr. Alberto Suero" Forestry Center, Nursery of the Isla Victoria Botanical Garden in Nahuel Huapi National Park (NHNP), to which I belong as a contracted agent. Native forest seedlings are produced for ecological restoration purposes. Throughout the internship, numerous important data were collected for proper crop management, such as the selection of seed specimens, locations and dates of seed harvesting of native plants with conservation value, their conditioning and storage, pre-germination treatments, sowing dates, types of substrates used for the different cultivation stages, and the specific requirements and development times of the different species. Ecosystem restoration is a process that reverses degradation, through which the natural environmental functions of a site are recovered. Some of the tasks involved in ecological restoration include: surveying native species and the characteristics of the site to be regenerated; propagating plants for reforestation with native plants; and controlling invasive exotic species, among other actions. Native species nurseries have become strategic and necessary for projects to restore degraded environments, for reforestation, and for environmental education (Lacoretz et al., 2021). 2023-01-01T00:00:00Z http://rid.unrn.edu.ar:8080/handle/20.500.12049/13429 Título: Evaluación de la calidad de plantines de roble pellín producidos bajo dos sistemas de fertilización. Autor(es): Svampa, Suyai Abstract: The Dr. Grenville Morris Agricultural Experimental Station (INTA EEA Bariloche) operates in the city of San Carlos de Bariloche, Río Negro province. The EEA Bariloche operates four major work areas, including the Forestry Area. The research and development lines within this Area geographically cover the mountain and foothill areas, from the northern part of Neuquén province to the northern part of Chubut province. The objective is to understand the dynamics and functioning of forest systems and generate tools for their management, thus contributing to the sustainable development of the region. The Ecological Genetics and Forest Improvement Group, the unit in which the work experience described here was carried out, aims to generate information to contribute to the conservation and sustainable use of the genetic resources of forest species of ecological and/or economic importance in the region. The work within this group ranges from genetic characterization studies of natural populations, aimed at the identification and conservation of genetic stocks, to improvement programs for forest species with productive potential, both native and exotic (INTA, 2022). The research group has a Forest Nursery where the seedlings required for the research lines are produced, and where the activities comprising this Internship were carried out. Within the framework of a Pellín oak plant production program intended for field experimentation within the group's various lines of research, the internship proposal consisted of evaluating a batch of seedlings obtained through two different fertilization methods to characterize their quality. 2022-12-15T00:00:00Z http://rid.unrn.edu.ar:8080/handle/20.500.12049/13427 Título: Cultivo de plantas bulbosas de flor en la ciudad de Bariloche. Autor(es): Soler, Victoria Abstract: This report covers the final work experience for the Nursery Technician program at the National University of Río Negro and is the result of work carried out at the Danubio Farm in the city of San Carlos de Bariloche. It describes the various aspects related to the cultivation of bulbous plants in the field, with varieties of tulips and daffodils. Cultivation tasks are included from October 2023 to January 2024. In the 1950s, the first ornamental plant production facilities were established in the city of Bariloche, in the Andean region of the province of Río Negro. During the 1960s and 1970s, other nurseries were added, some of which are still in operation today. Significant urban growth, accompanied by a strengthening of tourism, drove a growing demand for plants and flowers for use in parks and gardens. This development has allowed the city to currently boast a significant sector of ornamental plants that contribute to the beautification and give identity to its urban landscape. Bariloche, with more than 20 producers and nurseries selling plants and flowers to the public, forms a production and value chain that seeks to position the quality of its products in the region and the country. (Andersen et al., 2016) Regarding experiences in Bariloche, Chacra Danubio is a bulb producer, with half a hectare planted with acclimatized Dutch tulips (it also produces varieties of daffodils, irises, and hyacinths, among others). It has successfully supplied the local and regional markets with its bulbs for more than 50 years (Robredo, 2017). 2024-08-13T00:00:00Z http://rid.unrn.edu.ar:8080/handle/20.500.12049/13425 Título: Propagación de salix humboldtiana para rescate genético de la especie y restauración de riberas. Autor(es): Hansen, Marina Anahí Abstract: Salix humboldtiana, commonly known as the Creole willow, is a deciduous tree belonging to the Salicaceae family. This species is distributed from Mexico to northern Patagonia in Argentina and Chile. In Argentina, it can be found from the northern provinces to Chubut. This tree species prefers low, sandy soils and is common along riverbanks and streams. Salix humboldtiana, commonly known as the Creole willow, is a deciduous tree belonging to the Salicaceae family. This species is distributed from Mexico to northern Patagonia in Argentina and Chile. In Argentina, it can be found from the northern provinces to Chubut. It is a tree species that prefers low, sandy soils and is common along river and stream banks. In the Patagonian region, Salix humboldtiana primarily lives in riparian areas, where it stands out for its rapid growth and remarkable adaptability to diverse environmental conditions. Its leaves are long, narrow, and bright green, while its young branches are flexible and grow quickly, and it has a characteristic thick, ridged bark. This tree can reach heights of up to 20 meters, developing broad, open crowns. It has unisexual flowers arranged in catkins. The species is dioecious, meaning it has both male and female specimens. The male flowers produce pollen, while the female flowers generate seeds after pollination. The seeds of the Creole willow are small, 1 to 2 millimeters, lightweight, and have trichomes (hairs) that facilitate their dispersal by wind and water. However, without the mediation of these dispersal factors, this hairiness acts as a germination inhibitor. 2024-01-01T00:00:00Z http://rid.unrn.edu.ar:8080/handle/20.500.12049/13424 Título: Producción de plantines de lenga. La incidencia del origen y las condiciones de almacenamiento de la semilla en su calidad. Autor(es): González, Javier Alejandro Abstract: INTA is an agency under the Secretariat of Bioeconomy of the Ministry of Economy of the Nation. It was created by Decree Law 21680/56 on December 4, 1956, when capacities began to be developed to supply the agroindustrial sector with knowledge and technology. Through communication and extension systems, the various technologies and knowledge generated are made available to society. In particular, INTA's forestry activities related to native forests benefited from the creation in 2007 of Law 26.331 "Environmental Protection of Native Forests," with minimum budgets for environmental protection, restoration, conservation, and sustainable management of Argentina's forests. Among other objectives, this law seeks to establish territorial management of native forests according to their state of conservation and environmental characteristics. The "Doctor Grenville Morris" Agricultural Experimental Station (INTA EEA) is located in the city of Bariloche (Rio Negro), where the Forestry Department is one of its research and work areas. Thanks to the results obtained, the conservation value of different forests can be identified in relation to their genetic variation, which contributes to the territorial reorganization of the ecosystems that comprise them. 2024-01-01T00:00:00Z http://rid.unrn.edu.ar:8080/handle/20.500.12049/13423 Título: Caracterización de los viveros productivo- educativos de la Universidad Nacional de Río Negro en la Ciudad de San Carlos de Bariloche. Autor(es): Gennaro, Gabriel Eduardo Abstract: The internship took place at the educational incubators of the National University of Rio Negro, which was established in December 2007 under Law 26.330. The first academic year began in March 2009. The Nursery Technician program is offered at the Andean Campus in the city of San Carlos de Bariloche. It is a three-year program. Thus, graduates are equipped to develop sustainable production programs for horticultural, ornamental, aromatic, and forestry plants, applying technologies specific to each type of production. They can also organize social, research, and educational programs focused on environmental production for plant production. From the Latin vivarium, "a nursery is an agronomic facility where all types of plants are grown, germinated, and matured." Nursery production can be classified according to its field or indoor production system; it can be in containers or on the ground, depending on the type of sexual or asexual propagule. It is also classified according to whether it is experimental or commercial. Recently, the educational nursery methodology has been added as a teaching methodology, and progress has been made in production systems at universities. In the following work experience, I will develop the technical and botanical characterization of the educational nurseries at the National University of Rio Negro. The nurseries have developed and become more technical over time, with the input of students and professors during the internships and with the participation of the cross-curricular subjects taught at the facilities. 2023-12-22T00:00:00Z http://rid.unrn.edu.ar:8080/handle/20.500.12049/13422 Título: Propagación de especies nativas leñosas. Autor(es): Espinoza Consoli, Simón Mario Abstract: The Victoria Island Forest Nursery was the first nursery in Patagonia, operating since 1924, with closures and reopenings. In 2009, in a context of economic recovery and as part of a larger project, the "Alberto Suero Agricultural Engineer Forestry Center" was created within the Victoria Island Botanical Garden. This center is dedicated to the production of native species under environmental paradigms related to genetic conservation. Since the National Parks Administration (NPA) has environmental conservation among its main functions, it was decided that the institution would generate its own plants. In this way, the exact origin of the propagated material is known, avoiding genetic contamination that can be caused by the introduction of individuals of unknown origin. The plants obtained are intended to provide self-sufficiency to the institution itself, as well as to other local institutions, whether for repopulation or recovery of areas degraded by fires, or for urban trees. 2024-01-01T00:00:00Z http://rid.unrn.edu.ar:8080/handle/20.500.12049/13420 Título: Circuito productivo en el Establecimiento Hidroponía del Bosque. Autor(es): Eggui, Gabriela Jorgelina Abstract: Hydroponics is a so-called "soilless" or "landless" cultivation system, in which plants obtain the nutrients they need for growth directly from the nutrient solution and mineral salts with which they are irrigated. Its origin dates back to the Hanging Gardens of Babylon, and it was also used by the people who lived on the shores of Lake Titicaca in Bolivia or Peru, who grew their vegetables on straw with their roots in water. In 1930, Dr. W.E. Gericke of the Department of Plant Nutrition at the University of Berkeley, California, USA, researched and developed nutrition for a commercial system. The subsequent use of plastics—due to their mechanical, photometric, durability, strength, and optical properties, as well as their ability to replace concrete and metal in buildings and tanks—brought significant progress to the systems. As soil cultivation became more difficult, new formulations were developed. Research is being conducted on the relationship between nutrients and crops, and these formulas will later be applied to hydroponic cultivation. Starting in 1982, the hydroponic cultivation system emerged with further research on micronutrients, root oxygenation, cultivation structures, and inert substrates. With technological advances, computerized controls, the use of alternative energy sources (solar and wind), desalination of seawater or hard water, and more are being applied to this system. 2022-10-19T00:00:00Z http://rid.unrn.edu.ar:8080/handle/20.500.12049/13417 Título: Informe de práctica laboral Jardín Botánico Carlos Thays Autor(es): Mateo Tribelhorn, María Celeste Abstract: Currently, Botanical Gardens are taking on new roles. On the one hand, they continue to fulfill their traditional role in scientific research, collection curation, public engagement with residents, and education, but on the other hand, they have had to commit to new tasks, such as the restoration of degraded habitats, the maintenance of germplasm banks, and the social approach to conservation. This internship included a tour of the Carlos Thays Botanical Garden (JBCT), understanding its role, organization, and operation, participating in plant propagation activities, and applying the knowledge and tools acquired throughout their training as a nursery technician. The internship included specific activities within the propagation greenhouse and the research projects that the JBCT carries out in response to various needs, both its own and those of others. The functions of the different areas and the actions through which they carry out the roles within it were recognized. One of the most important areas within the JBCT is the Butterfly Garden, specifically designed to attract butterflies to the open air through plants that provide food and breeding sites. Within this sector, work was carried out on the propagation of the Asclepias curassavica (Apocynaceae) species, revealing the presence of photoblastic dormancy in its seeds. Two research projects were investigated in depth: "Unique specimens from the garden: Phenology and Propagation" and "Propagation of species native to the River Plate biota." Within the former, participants participated in a second germination trial of Schotia afra (Leguminosae); this species is susceptible to fungal attack, so two disinfection methods were tested, obtaining the best results with bleach (Dilution: 55 ml/liter of H2O). S. afra presents physical lethargy, so it was subjected to mechanical scarification with a pyrographer, obtaining a 22% total germination and 50% survival in container. Within the second project, it was part of a first germination trial of Senna corymbose (Leguminosae), it was determined that this species is susceptible to the invasion of the beetle Sennius lateapicalis (Pic 1927) whose larvae feed on this plant. The pregerminative treatment that resulted in the highest germination power (PG) was the control (92%), however, the one that produced the highest germinative energy (EG) was the one subjected to thermal and mechanical scarification, a PG of 83% was achieved, the latter being the recommended treatment. 2020-03-11T00:00:00Z http://rid.unrn.edu.ar:8080/handle/20.500.12049/13416 Título: Ensayos de germinación de semillas de tomate platense (Solanum lycopersicum) inoculadas con levaduras y actinobacterias Autor(es): Mari, Ana Eugenia Abstract: Soil microorganisms comprise a large group of organisms that can be pathogenic or beneficial and are concentrated mainly in the rhizosphere (the zone near the roots), between 2 and 10 cm deep. They can tolerate poor soils with low moisture content. They play a fundamental role in the degradation of soil organic matter and maintain its fertility. The yeasts and actinobacteria (eukaryotic fungi and prokaryotic bacteria, respectively) used in this study are microorganisms native to northern Patagonia, which generate beneficial symbiotic associations with plants. These microorganisms adapt to salinity conditions that others cannot tolerate and promote plant growth. They can withstand high salinity environments (10% w/v). They have the ability to improve the absorption of water and phosphates, among other nutrients, they produce siderophores (which aid nutrient absorption by plants), they produce auxins, gibberellins and cytokinins, plant growth regulating hormones such as indole-3-acetic acid (IAA) (which influences root growth), they also produce antifungals and antibiotics (inhibiting the proliferation of pathogens). Therefore, they influence drought tolerance and improve plant establishment, growth and yield, they are regulators of soil pathogens and controllers of post-harvest diseases. For this reason, they are part of the group of microorganisms to be used as an innovative form of crop management, as biocontrol agents and plant growth promoters (El-Tarabily et al., 2003-2006; Mestre et al., 2016; Solans et al., 2022). 2023-05-05T00:00:00Z http://rid.unrn.edu.ar:8080/handle/20.500.12049/13412 Título: Cultivo de Nothofagus alpina "raulí" en condiciones de invernadero a partir de semillas procedentes de bosque natural. Autor(es): García, Viviana Edith Abstract: The internship was carried out within the framework of a Research Commission Agreement between the National Institute of Agricultural Technology (INTA) and the National University of Río Negro. It was developed at the Bariloche Agricultural Experimental Station (EEA) of the Argentine Institute of Agricultural Technology, which focuses on research and extension. The Bariloche EEA has an area of influence that encompasses the province of Neuquén and part of the province of Río Negro, characterized primarily by arid and semi-arid ecosystems that have shaped extensive production systems focused primarily on goat and, to a lesser extent, cattle farming. The unit is divided into four groups: Ecophysiology, Insect Ecology, Silviculture and Ecological Genetics, and Forest Improvement. The initial lines of research of the Ecological Genetics and Forest Improvement group (1993) focused on the native species of raulí and corrillera cypress. Currently, we work with seeds from identified forests and trees, ensuring their traceability throughout the production process. In addition, this sector aims to train the various actors in the production chain and generate new technologies and management methods to disseminate in the region's nurseries. 2023-08-10T00:00:00Z http://rid.unrn.edu.ar:8080/handle/20.500.12049/13411 Título: Actividades primaverales de viverización en vivero Terruños de Patagonia Autor(es): Brandstetter, Marión Inés Abstract: This report presents the results obtained from a work placement at the "Terruños de Patagonia" nursery in Bariloche, S.C., from September to December 2021.

Abstract: The Institute of Floriculture of the INTA carries out programs for the improvement of native species of ornamental value in order to generate national varieties adapted to the ecological cultivation conditions of our country. In recent years, the Institute has announced the new varieties obtained with native germplasm of the genera Mecardonia, Calibrachoa, Glandularia and Nierembergia, among others, many of which are already inserted in the market. Since 2013, the INTA Bariloche Agricultural Station has undergone the evaluation of some of the INTA ornamental varieties with the objective of developing crop management practices in order to obtain a quality product adapted to the region. From this work it is concluded that INTA evaluates varieties can be grown in a pot under greenhouse and it is possible to root from material from pruning of plants in winter. 2019-05-05T00:00:00Z http://rid.unrn.edu.ar:8080/handle/20.500.12049/3643 Título: Vivero Tierra Baldía. El Bolsón, Río Negro, Argentina. Manejo y producción de plantas ornamentales Autor(es): Miranda, Carla S. Abstract: A nursery is a set of facilities whose purpose is the production of plants, this can be under cover or field. The production under cover provides the necessary conditions (light, temperature, humidity) for its normal growth and development. The goal in a nursery is basically the production, propagation, cultivation and distribution and sale of plant species, used by man with different objectives; for example, productive (forestry, ornamental, horticultural) also in places that suffered great deforestation (fires, uncontrolled urbanization, indiscriminate logging, natural catastrophes) with the consequent loss of biodiversity. This paper reports the activities carried out at the Vivero Tierra Baldía, located in El Bolsón, Río Negro, whose owner, Mr. Bruno Angelino, with more than 40 years of experience dedicated to the nursery market, as well as the production of seedlings, sale of trees, shrubs, indoor and outdoor plants, ornamentals, cacti and succulents on a large scale. It has two sectors to develop its activities located in the area of El Bolsón and El Hoyo, Chubut. It is recognized by the people of the area, appreciated for the good care of the plants and their attention to the public, always providing advice with experienced staff. 2019-06-14T00:00:00Z
