| 摘 要： | 对6个性状的光照边际效应系数，以及单株产量光照边际效应系数与其它性状光照边际效应系数的相关性进行了分析。结果表明：普通栽培条件下光照因素在玉米的边际效应中作用较小，但是客观存在，且品种间有差异，光照主要通过影响行粒数和穗长等性状来增加边行的单株产量，光照因素在穗行数的边际效应中影响甚微。

| Abstract: | Six characters' marginal effect coefficient of illumination was figured up through the difference between 8 varieties' marginal plants of south and north maize fields.At the same time,the correlation analysis of illumination marginal effect coefficient between the character of yields per plant and the others character was studied.The result showed: in nowadays cultivation conditions,the illumination had a little contribution to marginal effect,but it was existed indeed and changed with different varieties.Caused by illumination,the yields per plant was increased orderly by the changes of grain number per row,ear length,ear thick,weight per 1 000 grains.The illumination had almost no effect on grain row per ear of marginal plants. |
