ABSTRACT
In order to characterize and design a dichotomous key for identifying weeds diasporas in the diasporas land bank, were collected and characterized diasporas of 47 species of the most aggressive weeds in agroecosystems reported in Cubans lands. The work of collection was carried out between June 2013 and March 2014 in the areas of the campus of the Central University “Marta Abreu” of Las Villas, the Botanical Garden of Villa Clara, the Experimental Station “Álvaro Barba Machado “, the Basic Unit of Cooperative Production # 3 Valle de Yabú and Topes de Collantes Protected Natural Landscape. The main features of the diasporas were characterized considering size, three-dimensional shape and contour, surface, and special characters for the dispersion are recorded, allowing the collected differentiate diasporas and shape the design of a dichotomous key, to be used for it which detached single entry model was used.
