摘要： 为了探讨灌浆期小麦上三叶叶绿素含量与产量和品质性状之间的关系，以49个基因型为参试材料，对上三叶叶绿素含量、穗粒数、千粒重、穗粒重、蛋白质含量和湿面筋含量进行测定。结果表明：基因型间、上三叶间、不同灌浆期间叶绿素含量均存在较大差异，基因型间穗粒数、千粒重、穗粒重、蛋白质含量和湿面筋含量也存在较大差异；上三叶叶绿素含量与穗粒数、千粒重、穗粒重、蛋白质含量和湿面筋含量均呈正相关关系，其中5月10日倒三叶、5月15日倒二叶和倒三叶、5月19日倒二叶和倒三叶与穗粒数达到显著或极显著相关，5月19日旗叶和倒二叶和5月24日上三叶（旗叶、倒二叶和倒三叶）与千粒重均达显著或极显著相关，5月10日倒三叶、5月15日倒二叶和倒三叶、5月19日上三叶（旗叶、倒二叶和倒三叶）和5月24日旗叶和倒二叶与穗粒重相关性均达显著或极显著水平，除5月10日旗叶外其他叶绿素含量与蛋白质含量和湿面筋含量均达显著或极显著水平。灌浆期上三叶叶绿素含量对产量和品质性状有重要影响。

Abstract: To study on relationship between chlorophyll contention of top-three leaves at grain filling stage and grain yield and quality traits in wheat, the chlorophyll contention of top-three leaves, spike grain number, 1000-grain weight, spike grain weight, protein content and wet gluten content were measured with 49 wheat genotypes as the experimental material. The results showed that: the difference was significant between genotypes, top-three leaves, different grain filling stages. The difference of spike grain number, 1000-grain weight, spike grain weight, protein content and wet gluten content between genotypes were significant; chlorophyll content of top-three leaves and spike grain number, 1000-grain weight, spike grain weight, protein content and wet gluten content were positive correlation, it was significant that the correlation between spike grain number and the second top leave on May 10th, the second top leave and the third top leave on May 15th and on May 19th, it was significant that correlation of 1000-grain weight and flag leave on May 19th, top-three leaves (flag leave, the second top leave and the third top leave) on May 24th, the correlation between spike grain number and chlorophyll content of the third top leave on May 10th, the second top leave and the third leave on May 15th, the top-three leaves (flag leave, the second top leave and the third leave) on May 19th, flag leave and the second top leave on May 24th were significant. It were significant that correlation of chlorophyll content of different grain filling stages expert flag leave on May 10th and protein content and wet gluten content. There was important influence on grain yield and quality traits about chlorophyll content of the top-three leaves in grain filling stage.
