| 摘 要： | 通过对百脉根单株的11个农艺性状的相关分析,结果表明:分枝长度(X2)、分枝节间数(X3)、分枝茎粗(X4)、侧枝数(X6)、侧枝长度(X7)、侧枝节间数(X8)、侧枝茎粗(X9)对单株产量(Y)的作用达到极显著水平,分枝数(X1)、自然高度(X11)与单株产量的相关性达到显著水平,而分枝叶柄长度(X5)、侧枝叶柄长度(X10)则与产量的相关性不显著.通径分析结果表明:各性状对产量的直接效应从大到小依次为:分枝长度(1.121 6)>分枝节间数(0.346 3)>侧枝长度(0.114 6)>分枝数(0.106 4)>分枝茎粗(0.084 6)>侧枝节间数(0.034 2)>侧枝茎粗(0.028 9)>侧枝数(0.021 6)>侧枝叶柄长度(-0.043 6)>分枝叶柄长度(-0.065 4)>自然高度(-0.748 2).

| Abstract: | The correlation and path analysis of 11 agronomic characters were studied with per plant in Lotus corniculatus.The results showed that yield(Y) of per plant was extremely significant affected by branch length(X2),branch nodes(X3),branch stem diameter(X4),the number of sub-branches(X5),sub-branch length(X7),sub-branch nodes(X8) and sub-branch stem diameter(X9),and significantly affected by the number of branches(X1) and natural height(X11).However,no noticeable correlation was found between yield(Y) of per p... |
