在三种桉树挥发油及其主要成分对蚕豆根尖细胞抑制作用中，大叶桉挥发油的抑

Of the three major components Eucalyptus Essential Oil cytostatic effect on broad bean root tip, the strongest inhibition Eucalyptus Essential Oil, its integrated value reaches the allelopathic effects of 0.524 M, Eucalyptus grandis volatile oil Vicia faba root tips inhibition times , its integrated value of 0.469 M allelopathic effect, inhibition of eucalyptus globulus volatile oil weakest Vicia faba root tips, which is integrated allelopathic effects 0.430 M; comparison of three volatile oil of eucalyptus by two main components α- pinene integrated value M contrast feeling ene and 1,8 cineol effects on stomatal guard cells and the root tip cells found are arranged P1> E1, P2> E2, P3> E3 order according to the strength of inhibition.

In the inhibition effect of three kinds of eucalyptus volatile oil and its main components on the root cell of broad beans, the inhibition effect of large leaf eucalyptus volatile oil is the strongest. Its integrated sense effect M value reached 0.524, the inhibition effect of giant eucalyptus volatile oil on the root cells of broad beans was second, its combined sense effect M value was 0.469, the inhibition effect of blue-sprigoil on the root cell of broad beans was the weakest, and its combined sense effect M was 0.430; , 8-Ofthepho-oil oil to the broad bean gas hole protection cells and root-tip cells of the combined sense effect M-value comparison found that in order of inhibition strength and weakness in order of P- E1, P-E2, P-E3.

Among the three kinds of Eucalyptus volatile oil and its main components, Eucalyptus grandis has the strongest inhibitory effect on Vicia faba root tip cells, and its comprehensive allelopathy m value reaches 0.524, Eucalyptus grandis volatile oil has the second inhibitory effect on Vicia faba root tip cells, its comprehensive allelopathy m value is 0.469, and Eucalyptus globulus volatile oil has the weakest inhibitory effect on Vicia faba root tip cells, and its comprehensive allelopathy m value is 0.4 30. By comparing the synthetic allelopathic effect of α - pinene and 1,8-cineole on the stomatal guard cells and root tip cells of Vicia faba, it was found that P1 > E1, P2 > E2, P3 > E3 in the order of inhibition.
