Evaluación de la calidad de plantines de roble pellín producidos bajo dos sistemas de fertilización.

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.
