摘　　要：连续 10年 ,总共用东北大豆 4 0 0多个品种 (系 ) ,在品种资源研究圃测定不同品种叶绿素含量 (a +b)。表现品种间差异明显 ,高者 3.4 7mg/dm2 ,低者 2 .17mg/dm2 ,平均为 2 .62mg/dm2 。从中筛选出 4 0多个叶绿素含量高、丰产性好品种 (系 ) ;并按年度、品种熟期分组进行叶绿素含量与产量相关分析。各组相关程度不同。总的趋势是呈正相关、10年平均r =0 .36。说明大豆在结荚期叶片的叶绿素含量对产量形成起重要作用 。Chlorophyll content (a+b) were tested in the study of varieties resource over ten years involving 400 Northeast spring soybean. The experiments show that there is a significant variance among varieties :the highest is 3.47mg/dm 2, the lowest is 2.17mg/dm 2 and the average is 2.62mg/dm 2. Forty soybean with higher chlorophyll content and yield were collected for correlation study between chlorophyll content and yield according to year and maturity. The result show there is a different correlation extent i...
