Irvingiagabonensis, commonly called « Kaklou », is a highly valued species at the culinary level, in the center-west of the Côte d’Ivoire country. It is an endangered species due to overuse of its almonds. Thus it appears necessary to study its germination process in order to domesticate it. This is what has been done through the establishment of a germination test at the research station of the CNRA (National Centre for Agronomical Research) in the center-west of the country. Two treatments were used for the germination test: T1: sowing of the seed with its endocarp, T2: sowing of the seed without its endocarp (removal of the almond from stone, seed with shell removed). The seeds with endocarp (T1) germinate in 40 days and their germination spreads over one month. As for the seeds without endocarp (T2), they germinate in 9 days and their germination spreads over 21 days. The low germination rate in T1 is due to the fact that the fruits may fall too early or to a parasitic attack that can destroy the vital part of the seed. Indeed, in the extraction method, we noticed that for 100 fruits, more than 60 seeds were rotten. Hence the best treatment is T2.In Côte d’Ivoire, spontaneous food plants exploitation and marketing are secured by women, seldom by men and children. This area of activity remains informal and deserves to be organized so as to fight poverty.
