摘要:

过氧化氢(hydrogen peroxide, H2O2)作为一种重要的活性氧(reactive oxygen species, ROS)信号分子,通过调控氧化还原反应参与细胞应答各种胁迫信号,在植物抗逆过程中扮演着重要角色。适量的外源H2O2能够缓解非生物胁迫对植物的伤害,甚至可加快其生长和发育进程,例如促进种子萌发和幼苗生长等。此外,H2O2具有无色无毒、强光下易分解等环境友好特性。因此,深入探索其在非生物胁迫下对植物生长与生理代谢的影响尤为重要,对于未来广泛应用H2O2作为植物生长调节剂从而提高作物产量和抗逆性等具有重要的实际意义。基于此,本文归纳与总结了在非生物胁迫条件下外源H2O2调节植物生长与生理的研究进展,从种子萌发、幼苗生长、开花、结果的生长过程以及光合作用、抗氧化防御系统的生理响应两大方面进行综述,旨在明晰植物的响应机制,以期为未来H2O2在农业生产中的广泛应用提供一定的科学依据。

Abstract:

Hydrogen peroxide(H2O2)as an important signal molecule of reactive oxygen species(ROS), plays an important role in the process of plant stress resistance by regulating REDOX reaction and participating in cell response to various stress signals. It not only participates in and regulates the cell response to various stress signals, but also plays an important role in the process of REDOX reaction and stress resistance. Appropriate amount of exogenous H2O2 can alleviate the damage of abiotic stress to plants, and even accelerate their growth and development process, such as promoting seed germination and seedling growth. In addition, H2O2 is colorless, non-toxic, easy to decompose under strong light and other environmentally friendly characteristics. Therefore, it is particularly important to deeply explore the mechanism of exogenous H2O2's influence on plant growth and physiological metabolism under abiotic stress, which has important practical significance for widely applying H2O2 as an effective plant growth regulator to promote plant growth and improve crop yield and stress resistance in the future. Based on this, this paper induced and summarized the research progress in exogenous H2O2 regulating plant growth and physiology under abiotic stress, and reviewed the growth process of seed germination, seedling growth, flowering and fruit bearing, as well as the physiological response of photosynthesis and antioxidant defense system, aiming to clarify the response mechanism of plants and to provide a certain scientific basis for the wide application of H2O2 in agricultural production in the future.
