| 摘 要： | 以培矮64S/R 292,Y 58S/R 292为材料,以丰源优299为对照,研究了水稻倒3叶叶长、叶宽、叶片披垂度、叶片卷曲程度等主要形态指标及其与产量的相关性。结果表明：培矮64S/R 292,Y 58S/R 292叶片所处空间层高,叶片卷曲程度大,叶片挺直,不遮阴下部叶片,有效光合面积大,光合态势好。与产量相关性分析表明,倒3叶叶长、叶宽、叶片卷曲度与产量显著正相关,叶片披垂度与产量显著负相关。

| Abstract: | Major morphological indexes,length and width of the third leaf from top,bend degree of leaf and curly degree of leaf and their correlation to yield were studied with Pei'ai 64S/R292,Y58S/R292 and Fengyuanyou 299(CK) as materials.The results showed that the space of the leaves of Pei'ai64S/R292 and Y58S/R292 was higher,the curly degree of leaves was larger,the leaves were straighter,the effective photosynthesis area was larger and photosynthetic situation was better.The correlation analysis showed that signi... |
