对2个新构建的瑞德和非瑞德玉米优势群体在2种高密度条件下不同发育时期植株性状的分析结果表明,高密度使大多数植株性状的平均数减小,变异系数增大,有利于提高选择效果;各植株性状的密度效应因群体和发育时期不同而异;高密度条件下茎粗的减小和穗位高的增加,有利于对植株抗倒性的选择。
The analysis of plant traits at two different developmental stages under two high density conditions showed that the average density of most of the plant traits decreased with the increase of the coefficient of variation, The density effect of each plant trait varies with the population and development period. The decrease of stem diameter and the increase of ear height under high density conditions are favorable for the selection of plant lodging resistance.
