| 摘 要： | 利用灰色关联分析方法,研究了10种不同基因型的超高产冬小麦收获指数与灌浆期旗叶光合特性的关系.结果表明,各光合指标与小麦收获指数的关联度大小依次为:叶绿素b(0.8381)＞叶绿素a/b(0.827 2)＞叶绿素a(0.819 2)＞净光合速率(0.771 2).可以看出,小麦收获指数与叶绿素b含量及叶绿素a/b间关联...

| Abstract: | With 10 genotypes of wheat cultivars as materials,the relationship between the harvest index and the flag leaf photosynthesis characteristics during grain-filling stage was studied by gray correlation analysis method.The result indicated that the order of correlation to wheat harvest index was chlorophyll b content(0.8381)>chlorophyll a/b(0.8272)>chlorophyll a content(0.8192)>net photosynthesis rate(0.7712).The factors markedly closer to the wheat harvest index were the chlorophyll b content and the ratio of chlorophyll a/b among the above four factors,and during cultivar breeding and selecting,which were important parameters. |
