In Mexico by diverses circunstances many uncurtivated plant speaes are in process of extindion losing inportant characteristics that could be suited to preserve species of high genetic value. economic and cultural.
The ilama (Annona diversifolia Saff.) is a not commercial crop, but is cultivated as a backyard species utilized as alive fence. In Mexico this could be a problem of investigation with special remark because many of the vegetable resources have not received enough attention and unknowing how to increase them .
Using seed of a month of harvested in Tuxtla Chico. chiapas and storaged seed during two years coming from Chahuites, Oaxaca and research was leaded in order to asses the effect of age over germination. The sowing was realized in plastic tray containing a mixture of perlite and soil in a proportion of 2:1. Treatments evaluated were: soaking in wáter, scarification and adition of gibberellic acid in concentration of 200, 350 and 500 mg-lite-1.
The results showed that the germination was better in seeds of one month of harvested (20.5 %) that in storaged seed (2.5 %).The higher percentage of gemlination (20.5 %) occur with scarification plus gibberellic acid in 500 mg·liter-1.
