中文摘要：

小麦是世界上第一大粮食作物,田间杂草严重影响小麦生产。利用小麦化感作用控制田间杂草不会导致农药残留、杂草抗性和再猖獗等问题,是21世纪发展可持续农业的生物工程技术之一。该文主要从种质资源、化感物质及小麦化感作用在农业实践中的应用研究进行综述,探讨了小麦化感作用研究存在的问题,以期为促进小麦化感作用研究提供借鉴。

英文摘要：

Wheat is one of the largest crops in the world,however it is seriously affected by weeds during the process of production.The utilization of allelopathy in wheat to controll weeds in the field is considered to be one of the bio-engineering techniques,would not lead to ＂pesticide residues,weeds resistantance and rampancy＂ issue,to develop sustainable agriculture in the 21st century.This paper gave a review on wheat allelopathy,wheat allelopathic germplasms,allelochemicals and the application of wheat allelopathy in the agricultural practice.In addition,some problems in wheat allelopathy research are discussed,aiming to promote the study of wheat allelopathy in the future.
