Nut weight and nutrient contents of Cola acuminata and C. nitida (Sterculiaceae)
1989
Oladokun, M.A.O.
Cola acuminata and C. nitida nuts were classified into nut weight classes, and each nut weight class was divided into groups according to the number of nut cotyledons. The nuts in each group were analyzed for inorganic and organic constituents. Statistical analyses showed the effect of nut weight to be significant on nutrient composition in the two species (P = 0.001) while cotyledon number effect was not significant in C. acuminata. Germination percentage and growth performance varied directly with nutrient contents which, parenthetically, were positively and significantly correlated with the nut weights (0.77 < r < 0.99 and 0.1% <P < 5%). Relationship between nut cotyledon number and the nutrient contents was not consistent. The preferential taste for C. nitida by people as compared to C. acuminata is probably because the former contains more free sugar and is more nutritious.
