摘要
以正己烷作溶剂,用超声波浸提蒲江、洪雅两地的巨桉根系、根系土壤,用GC-MS检测其成分.结果表明,蒲江的巨桉根系、根系土壤的主要化感类别都是芳香酸酯;洪雅的巨桉根系的主要化感类别是长链脂肪酸,根系土壤的主要化感类别是烷烃.芳香酸酯等芳香族化合物的抑制作用可能是蒲江、洪雅两巨桉林地物种差异较大的主要化感原因之一,对今后化感成分的生理生化作用研究有一定的指导意义.

Abstract:
Root system,root system soil of Eucalyptus grandis(E.grandis)have been ultrasonically extracted with hexane in Pujiang and Hongya,and identified with gas chromatograph-mass spectrometer.The analysis results:the main allelopathic categories of root system、root system-soil of E.grandis contain arenoates in Pujiang;the main allelopathic categories of root system of E.grandis contain the long chains fatty acid,and the main allelopathic categories of root system-soil contain alkanes in Hongya.Inhibition of aromatic compounds,such as,arenoates,is possibly the main allelopathic reason of species diversity of the forest in the two regions.This research is value to study on the physiologic and bio-chemical functions of allelopathic of the E.grandis.
