| 中文摘要:油菜素内酯属于甾体类激素中的油菜素甾醇类物质,是其生物合成中产生的活性副产物,对植物生长发育具有重要的调节作用。在非生物胁迫条件下,外源施用油菜素内酯可以增强植物的抗氧化系统,增加渗透物质水平,维持内源激素平衡,稳定离子和水分平衡,改善气体交换属性和光合作用,最终减轻逆境危害并促进植物生长。该文综述油菜素内酯对非生物胁迫下植物生长、生理调节的影响及调控途径,对油菜素内酯提高植物抗逆境能力的未来研究方向进行展望。 |

| Abstract:Brassinolide is one of brassinosterols, a group of steroid hormones. It is an active by-product of brassinosterols' biosynthesis and plays an important role in regulating plant growth and development. Under abiotic stress, exogenous application of brassinolide can enhance plant antioxidant system,increase osmotic material level, maintain endogenous hormone balance, stabilize ion and water balance,improve gas exchange properties and photosynthesis, and therefore reduce stress damages and promote plant growth. In this paper, the effects of brassinolide on plant growth and physiological regulation under abiotic stresses were reviewed, and the possible research directions of brassinolide in promoting plant resistance to stresses were proposed |
