Abstract

The kinetics of protein and carbohydrate accumulation during seed development showed major differences between as well as within genotypes over the stages. Variation in protein content in a variety at different stages of seed development is recorded. The ratio between carbohydrate and protein biosynthesis was, in general, narrow during the last phase of seed development when protein accumulation mainly occurs. In contrast, the 18-24 days period after an thesis was favourable for carbohydrate biosynthesis. Correlation between carbohydrates and protein (mg/seed) was significantly positive and between carbohydrates and protein content negative. However, it has been shown that both carbohydrates and protein decrease or increase simultaneously though the magnitude differs. Variation for protein biosynthesis at different stages may be utilised for the development of more efficient system of protein biosynthesis.
