【摘要】 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。更多还原

【Abstract】 During 1995～1996,the grain filling characteristics were studied in different tight plant type corn hybrids.The results were as follows:Different tight plant type corn hybrids,100-kernel volume and weight increating from 5 to 30 days in them during grain filling were significantly different each other.Signficantly positiive correlation.were between grain volume with grain weight of corn hybrids .The No.of kernels perear,grain volume and grain weight are important factors of which the corn hybrid yield composed.更多还原
