| 摘 要： | 以根系伤流液的重量作为根系活力的指标,研究了吉林省1923～2004年育成的22个大豆品种在盛花期(R2),结荚期(R4)和鼓粒期(R6)根系伤流液重量的变化及其与功能叶片净光合速率(Pn)的关系.结果表明:根系伤流液重量与品种的育成年份呈正相关变化,但年度间表现存在差异,2009年没有达到显著水平,2010年在R2、...

| Abstract: | In order to understand the changes of root bleeding sap weight(BSW)and the correlation between root activities and leaf net photosynthesis during the genetic improvement,root BSW and leaf net photosynthetic rate(Pn)were measured at flowering(R2),pod bearing(R4)and seed filling(R6) stage with 22 soybean varieties bred in Jilin province from 1923 to 2004.The results showed that BSW was significantly or very significantly positive correlated with released years at R2,R4 and R6 stage in 2010,while didn't reach ... |
