Propagación de salix humboldtiana para rescate genético de la especie y restauración de riberas.

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.
