| 英文简介 | As a native plant species of Asteraceae in South America,Xanthium spinosum has been found in some areas of China,and it is a noxious,vicious invasive species which has widely spreaded in Ili River Valley of Xinjiang. The previous research indicated that the extracts from Xanthium spinosum possessed strong biological activity. However, the structure and species and mechanism of allelochemicals are in need of father investigation. The secondary metabolites of different parts of the plant will be extrated by different methods,and the allelopathic effects will be evaluated by conducting bioassays against six dicot plants and six monocot plants. According to the results of biological activity, the separation, purification, structural identification of allelochemicals will be performed. The purified compounds will be studied adopting these methods,such as testing of physiology and biochemistry, pot method and root-box experiments, by analying the affecting pattern of activity compounds, morphology ,cytohistoloy and physiological and biochemical indexes of receptor plants, and through which we can reveal the invasiong machnism of chemical ecology.The result will improve and perfect the contents of allelopathy studies of invasive plant species,promote the studies of chemical ecological machnisms,even the exploiting of new type of botanical pesticides.And at the same time, this work will provide some theoretical basis for the control and management of noxious invasive species in local area. |
