| 摘 要： | 通过对小麦物候期与主要农艺性状相关性的研究分析,结果表明：小麦物候期(挑旗期、抽穗期、开花期)与主要农艺性状之间存在着不同程度的相关。其中,挑旗期与抽穗期、开花期、小穗数、不孕小穗数、最高分蘖数呈显正相关;与旗叶长度负相关不显。抽穗期与开花期、小穗数呈极显正相关;与旗叶长度呈极显负相关;与倒三叶宽、倒三叶面积呈显正相关。开花期与小穗数呈极显正相关;与倒三叶宽、倒三叶面积呈显正相关;与旗叶长度呈极显负相关。

| Abstract: | In this article, the correlation between phenophase and some traits of wheat were studied. The results showed that the flag leaf at full expansion stage had significant positive correlation with the most tiller number, booting stage, flowering stage, sterility spike, fertility spike. Booting stage had significant positive correlation with flowering stage, fertility spike, the wide and area of the third leaf from top. There were significant positive correlation between flowering stages with the fertility spike let, the wide and area of the third leaf from top stage, booting stage, flowering stage had significant negative correlation with the length of flag leaf; however,the negtive correlation between the flag leaf growing stage and the length of flag leaf was not significant. |
