3.4 The soluble sugar content, starch content, andenzymes activities in
grains
In the laboratory incubation experiment of Exp. 3, the soluble sugar
content in both superior and inferior grains reduced with time and
remained stable from the 30th day after pollination
(DAP) to grain physiology maturity (Figure 7a). Similar soluble sugar
content was observed among treatments at different stage in both
superior and inferior grains with an exception of lower soluble sugar
content in DHS treatment on the 10th DAP. For starch
content, it showed an increasing trend in both superior grain and
inferior grains with time. In stress treatments, starch content in grain
was significantly lower compared with CK. On the 40thDAP, it was reduced by 12% in DS, 12% in HS, and 9% in DHS for
superior grains.
