| 摘 要： | 试验以高油玉米115为对照,对微胚乳超高油玉米在整个灌浆过程中,籽粒灌浆的生长进行分析,结果表明,籽粒活跃灌浆期和指数增长期比较短;对胚乳细胞数目的增殖分析知,微胚乳超高油玉米的胚乳细胞数目较少。对两类玉米灌浆过程中灌浆速度、灌浆持续期和胚乳细胞数与整粒干重的关系进行通径分析知:两类玉米整粒干重差异主要受胚乳细胞数与灌浆持续期的影响;对微胚乳超高油玉米籽粒来说,整粒干重的差异,并不主要受胚乳细胞数与灌浆持续期的影响,可能还有相对重要性状的影响,这还有待于进一步研究。

| Abstract: | With the high oil maize 115 as control to analyze the kernel and endosperm cells growing during the grain filling.The result showed that the active grain filling period and the exponential growth phase were shorter,and the endosperm cells of micro endospermsuper high oil maize were less.The difference of maize dry kernel weight were effected mainly by endosperm cell number and grain filling duration to common maize.But for the micro-endosperm super high oil maize,the variation of dry kernel weight was not e... |
