麦类作物化感作用及其分子生态学研究

Advances in the investigation of triticeae crop allelopathy and molecular ecology

摘要: 本文综述了近年来国际上研究麦类作物化感作用的新进展，着重介绍了小麦和大麦的化感作用种质资源的筛选与评价。在此基础上运用现代分子生物标记技术ISSR，分析了麦类化感作用的遗传多样性，并进一步阐明了小麦和大麦化感物质的研究现状。最后根据当前植物化感作用研究的发展趋势，提出化感作用基因表达与信号调控的分子生态学及根际生物学过程是未来麦类作物化感作用的重点领域。

Abstract: This article reviews recent advances in the investigation of triticeae crop allelopathy. The controversial research of wheat and barley allelopathic germplasm, resource screening and evaluation is discussed. The author also discusses genetic diversity of triticeae crops from molecular marker ISSR and allelochemical research. Finally, based on the development trend of research in plant allelopathy, the author highlights important issues deemed critical to the study of allelopathy of triticeae crops, including gene expression and signal regulation in molecular ecology and rhizospheric biological processes of wheat and barley allelopathy.
