3.2 The dynamic of grain filling process
The dynamic of grain dry matter accumulation was further investigated in
both Exp. 1 and Exp. 2 (Figure 5). At the beginning of grain filling (78
DAS), no significant difference for grain weight (1000-grains weight)
was observed among treatments. However, the subsequent grain filling
process was significantly impacted by the early stresses for both
superior and inferior grains.
