Influence of Water Deficit on Kernel Formation of Maize
The influence of water deficit at different stage in summer maize were studied under water control condition. The results showed that there were no significant influence on row number per ear and ear diameter of maize under different water treatments, but bare tip length and kernel number per row and aborted kernels number were significantly affected. There were no significant influence on ear characters and grain formation of maize under water deficit during 4 ~ 9 leaf stage. The anthesis-silking interval (ASI) of maize were prolonged, the rate of filament elongation were decreased, upper position filament extract difficult, the grain filling rate decreased and the kernel abortion rate increased significantly with the extension of soil water deficit period. The results also showed that soil water deficit affected the kernel development at upper position more seriously than those at the middle and lower positions.
