doi:10.3321/j.issn:1000-7091.2001.02.014

Abstract

Abstract: This study was conducted at Deng zhuang Experimental Station, Hengshui City, Hebei Province in 1994. The kernel filling process of winter wheat was observed. The results showed that the kernel weight mainly depended on length and strength of kernel filling period. The kernel filling process could be described by Logistic function. The beginning and peak of kernel filling could be delayed with better soil moisture condition. The highest kerne-l filling rate decreased as plant population increased.

Key words: Winter wheat, Kernel filling , Logistic model, Field management
