Study on Development of Summer Maize Kernel

doi:10.7668/hbnxb.2007.S1.014

Abstract

Abstract: Studies on the biochemical and physiological characteristics of kernel and cob development were conduct?? ed with summer maize hybrids Zhengdan 958 both in the field and lab measurement .The results showed as follows: the length of the ovary, fresh weight, dry matter accumulation and volume of kernels at the middle of ear were better than those of the upper part. The content of soluble sugar, protein and starch of the kernel and cob in different parts of the ear had different change trends, but the 12 day after anthesis( DAA) is a key day of the physiology characterist ics, all of the three indexes had changed after 12DAA.This study is of some scientific meaning for summer maize kernel development and high and quality maize production.

Key words: Maize( Zea mays L. ), Kernel development, Kernel abortion
