| 摘 要： | 发育中的马齿型(或半马齿型)玉米籽粒体积的增长,除受粒长变化的影响较大外,粒宽也不容忽视。玉米籽粒单位体积内所含干物质数量与籽粒含水率之间存在着极显著的负相关。玉米籽粒的干容重与试验地区的气温高低呈正相关,而玉米籽粒的体积则与温度、日照和降雨不表现明显的相关。

| Abstract: | Apart from the effect of variation of corn grain length upon the growth of the volume of developing horse-toothed(or half horse- toothed)corn grain,corn grain width can not be neglected.There is an extreme negative correlation between the amount of dry matter con- tained in per unit of corn grain and water content in corn grain.There appears to be a positve correlation between the dry bulk density of corn grain and the atmospheric temperature in the experimental region.But,the volume of corn grain appears to have no obvious correlation with temperature,sunshine and rainfall. |
