Abstract
Lantana camara,Verbenaceae family,is one of the invasive alien plants.Previous study about the allelopathy of L.camara mainly focused on exudates from stem and leaf,however,few study analysed the allelopathy of root exudates.At present,with the increasing of L.camara invasion expands scales,the plant has been expanded into farmland gradually.The aims of this study is to determine the allelopathy of different concentrations of water extracts from L.camara leaf and root on the germination and seedling growth of Vigna radiata,Brassica campestris,Triticum aestivum and Oryza sativa.Different parts and concentrations of water extracts from L.camara had different allelopathic effects on four receiver plants.Except the lowest concentration(2 mg/mL) had slight facilitation effects,other higher concentrations(20,50,100,200 mg/mL)showed significant inhibition effects and the inhibition increased with concentrations.The sensitivity of water extracts from L.camara was different among four tested species,B.campestris was sensitive to allelopathy of L.camara,while O.sativa was not.This study gave theoretical support for improving the competitiveness of crops aroud L.camara,and also provide a scientific foundation for control of current invasions and prevention of future invasions.
