| 摘 要： | 干旱胁迫是影响小麦生长发育与产量形成最主要的非生物胁迫因子,近年来化肥的过量使用及全球气候变化产生的不利影响,导致小麦在生长过程中受到的干旱胁迫危害日趋严重。植物根际促生菌(PGPR)不仅可以协助小麦提高养分利用率,促进其生长发育,还能够通过自身作用或产生多种代谢产物协助小麦抵御干旱胁迫。本文归纳总结了PGPR促进小麦生长及提高其抗旱性的研究进展,为利用PGPR提高小麦促生抗旱的研究奠定了理论基础。

| Abstract: | Drought stress is the most important abiotic stress factor affecting the growth and development and yield formation of wheat. With the adverse effects of excessive use of chemical fertilizer and global climate change, the harm of drought stress in the growth of wheat is becoming more and more serious. Plant growth promoting rhizobacteria (PGPR) can not only help wheat improve its nutrient utilization efficiency and promote its growth, but also help wheat to resist drought stress through its own action or various metabolites. In this paper, the mechanism of PGPR promoting growth was summarized, and the research progress of PGPR in improving wheat drought resistance was summarized from two aspects of physiological and molecular mechanism, which laid a theoretical foundation for the application research of using PGPR to improve wheat growth promotion and drought resistance. |
