摘　　要：为了明确不同光合性状在花生产量形成过程中的重要性差异,选择苗期、花针期、结荚期、饱果期和成熟期气孔导度、羧化效率、最大光化学效率、实际光化学效率、单株绿叶面积等主要光合性状与产量进行了灰色关联度分析。结果表明,在苗期、花针期和结荚期,羧化效率与花生产量的关联度最大,光合暗反应限制着光合产量的形成;而在饱果期和成熟期,气孔导度与花生产量的关联度最大,气孔张开的程度限制着花生产量的形成。In order to clarify the importance of different photosynthetic parameters in peanut yield formation,main photosynthetic parameters such as stomatal conductance,carboxylation efficiency,maximal photochemical efficiency,actual photochemical efficiency,leaf area per plant in the seedling stage,flowering and pegging stage,pod-bearing stage,pod-filling stage and mature stage were choosen to conduct grey correlation degree analysis with peanut yield.The results showed that in the seedling stage,flowering and pegging stage,and pod-filling stage,the association between carboxylation efficiency and yield of peanut was maximum,and photosynthetic dark reaction limited photosynthetic yield formation.In pod-filling period and mature period,the association between stomatal conductance and yield of peanut was maximum,the degree of stomatal opening limited the formation of peanut yield.
