油菜素内酯提高蔬菜作物抗逆性的研究进展

摘要

Brassinosteroids,a kind of novel plant endogenous hormone,are universally acknowledged as plant growth regulator with high activity,broad spectrum application,and non-toxic sterols in agricultural production.In recent years,it has been found that brassinosteroids can enhance plant resistance to various biotic and abiotic stresses, and promote plant growth and development,thus to further increase crops production. This paper summarizes the research progress made on brassinosteroids mediating vegetable resistance to multiple environmental stresses, including water,temperature,salt,pathogen,and heavy metal stress, etc.The paper also prospected some research directions in the future.%油菜素内酯化合物（Brassinosteroids，BRs）是国际上公认的一类高效、广谱、无毒的新型植物甾醇类生长激素。近年来研究发现，BRs的使用可显著提高植物对生物和非生物逆境的抗性，从而促进植物生长发育，大幅度提高作物产量。本文综述了BRs的类型、应用方式以及在提高蔬菜抵抗干旱、低氧、温度、盐离子、病害、重金属等环境胁迫方面的研究成果，并对未来的研究方向进行了展望。
