干母的致瘿结倍效果与倍蚜在同一枝条定叶取食复叶叶片萌发的先后顺序密切相关。角倍干母致瘿率和致倍率作为评价其致瘿结倍效果的指标 ,挂蚜干母的致瘿结倍效果指标 (yi)与盐肤木复叶萌发先后序数 (xi)之间的关系可用函数表达式 yi=A(0 ) +A(1) xi+A(2 ) xi2 +A(3 ) xi3 表示 ;寄生于不同序数复叶之间干母的致瘿率有显著差异 ;角倍蚜在盐肤木不同复叶叶序数上的致倍率 (y3值 )的排序为 :5>4 >6 >7>3>8>9>10 >11。该结果可作为调控角倍蚜干母的发生期以应合盐肤木最适致瘿结倍的展叶物候进度的参考依据。
The result of stemming and stemming of dry mother is closely related to the sequence of the leaf emergence of the double aphid in the fixed leaves feeding on the same branch. As for the index of doubling rate and multiplying rate, the result of the ratio of the induced effect of the stem aphid (yi) to the germination rate of the compound leaf of the tree shrub (xi) Relationship can be expressed as a function of function yi = A (0) + A (1) xi + A (2) xi2 + A (3) xi3 said; The results showed that the order of the doubling rates (y3) of the double aphids on the leaf numbers of different complex leaves was: 5> 4> 6> 7> 3> 8> 9> 10> 11. The results can be used as a control angle angle aphid dry mother of the occurrence of should be combined with the most suitable for skin Yan knot knot fold knot the progress of the progress of the reference.
