Research Advances in Allelopathy of Plants in Arid Desert Regions of Northwest China

摘要

To investigate allelopathy of plants in desert ecosystems,related research achievements obtained in recent years,reported allelopathic plants,allelochemicals and releasing ways of alleochemicalds were summarized,and then the key problems of research into allelopathic plants in desert ecosystems were indicated. It was considered that the research of allelopathy of plants in desert regions has just started in China,and plants with allelopathic potential were found in the Compositae,Leguminosae,Rosaceae,Scrophulariaceae and Gramineae; plants in desert regions release allelochemicals mainly via natural volatilization,which is closely related to their growing environment; allelochemicals such as alkaloids,flavonoids,terpenoids have been identified. This study can provide theoretical basis and practical value for reasonable adoption of protection measures of desert plants and comprehensive control of desertification.
