Asexual embryos of Theobroma cacao L. cultured in a liquid medium on a rotary drum apparatus were induced to produce storage lipids, anthocyanin, and alkaloids by increasing concentration of sucrose but not glucose, and only slightly by fructose or fructose + glucose at the same osmolarity. Glucose combined with sucrose or alternating with sucrose reduced lipid concentration as compared to sucrose alone. The concomitant development of lipids, anthocyanin, and alkaloids suggests that sucrose at high concentration regulates the initiation of embryo development.
