| 摘 要： | 为分析小麦冠层温度与产量性状的关系,选用55个不同基因型冬小麦品种(系),在灌溉条件下研究了不同冬小麦基因型产量性状,冠层温度差异及二者的相关性.结果表明,基因型间冬小麦的冠层温度在开花期、花后7 d、花后21 d和花后28 d均存在极显著差异.除花后21 d外,不同测量时期在重复间也均有极显著差异.开花期和花后21 d的冠层温度分别与穗数和穗粒数呈显著相关,灌浆期间冠层温度与千粒重呈显著或极显著相关.冠层温度与产量的相关性依次为花后7 d>花后21 d>开花期>花后28 d>花后14 d>抽穗期,其中花后7 d和21 d的冠层温度与产量呈极显著相关(P<0.01).冠层温度在灌浆中后期持续偏低与冬小麦绿叶功能和衰老机制的延缓有密切关系,可用于鉴定冬小麦产量潜力. |

| Abstract: | In order to investigate the relation between canopy temperature and yield characters from heading to physiological maturity,to determine optimal measurement times to estimate the genetic improvement for yield characters by canopy temperature,55 wheat cultivars and advanced lines of Shandong province in 2007-2008 cropping season under irrigated condition were used in this study.All materials were sown in randomized complete block design with 3 replications in Jinan.The results showed that genotype and replic... |
