Abstract

The purpose of this study was to examine the relationships between the soluble sugar content in the leaves and stems and the starch accumulation in the tuberous roots of four cassava cultivars- FuXuan01, GR891, SC124, and SC201. The results showed that the highest leaf soluble sugar content was in September, and the highest stem sugar content was in October, which played an important role in starch accumulation in the tuberous roots. The leaf and stem soluble sugar content and the tuberous root starch accumulation were positively correlated in the setting and growth stages but negatively correlated in the ripening stage. The soluble sugar content in the leaves went from high to low as the tuberous roots progressed from the setting stage to the ripening stage; starch accumulation in the root tubers followed the opposite pattern.
