| 摘 要： | 1986,1987年对5个旱稻品种不同生育期和不同密度的研究表明,籽粒干物质积累过程符合 Logistic 生长曲线,并达到极显著水平。籽粒可溶性糖和淀粉的变化趋势品种间大致相同,抽穗后第7天转运到籽粒的可溶性糖最多,之后,淀粉积累速率加大,抽穗后第27天淀粉含量达最高值。籽粒蛋白质积累在品种间差异较大。籽粒矿质元素以小白旱稻为最高,A7910次之,其它三个品种相差不大。

| Abstract: | This research was conducted in Beijing Agricultural University from 1986 to 1987,using five varieties of upland rice with different growth duration and different density.The results showed that the grain dry matter accumulation process of upland rice fired Logistic Growth Curve.The change tendency of soluble sugar and starch in grain among varieties was similar,the transfer of soluble sugar to grain was most on the 7th day after heading,later the accumulation speed of starch incrcased,and the starch content... |
