1995 ~1996 年对4 个不同紧凑株型玉米杂交种灌浆特性进行了研究,结果表明:不同紧凑株型玉米在灌浆期子粒体积增长动态彼此间表现差异显著;粒重增长的动态符合自然生长模式y = c/1 + ea - bx ,彼此间也表现差异显著;子粒体积和粒重呈高度正相关;子粒体积、粒重和穗粒数是决定产量的重要因素。
The grouting characteristics of four compact maize hybrids from 1995 to 1996 were studied. The results showed that the dynamic changes of grain size of different compact maize varieties at filling stage were significantly different from each other. The dynamic changes of grain weight accorded with the natural growth pattern y = c / 1 + ea - bx, which also showed significant differences among them. The grain volume and grain weight were highly positively correlated. The grain size, grain weight and grain number per spike were important factors in yield.
