| 摘 要： | 本文分析了10个特用大豆品种的几个生理性状与小区籽粒产量的相关性。结果表明:鼓粒初期叶绿素a、(a+b)含量与小区籽粒产量有显著的正相关,相关系数分别为0.7109、0.6799;光合速率、叶氮(％)、比叶重与小区籽粒产量的相关系数均不显著。通径分析表明:苗期和鼓粒初期的比叶重对小区籽粒产量有较大的负效应,开花期和鼓粒末期的比叶重对小区籽粒产量有较大的正效应。从24个因子中经逐步回归筛选得到一个含有6因子的回归模型:Y=4.0311+0.1625x_4+0.5569x_5-273.1188x_9-278.8875x_(10)+274.7645x_(11)-0.7925x_(10)用此模型模拟小区籽粒产量可靠性较好。

| Abstract: | The correlation between some characters and seed yield was analysed The result indicate that : There is a significant positive association between the content of chlorophyll a, chlorophyll b, chlqrphyll (a+b) at early pod-filling stage and seed yield(r=0.7109, 0.5106, 0.6799 respectively).No close correlation between seed yield and N content (%) of leaf, specific leaf weight was observed. Path analysis displays that during seedlisg and early pod-filling stages,specific leaf weight has a negative effect to seed yield, while during flowering and late pod filling stages spec fic leaf weight is positive to seed yield.regression equation content six factors was obtained by stepwise regression technique based on 24 factors. The equation is reliable to estimate the seed yield. |
