摘要/Abstract

摘要： 植物器官脱落是植物体的器官部分从母体脱离的现象, 是植物在生长发育和响应环境变化过程中进化出的一种适应性策略, 确保植物正常生长和适应环境。该过程涉及离层区形成、特定信号激活以及细胞分离, 同时还受自身生理进程及光照、温度和湿度等外部环境因素的显著调节。在农业生产实践中, 植物器官脱落直接影响作物的产量, 研究植物器官脱落的调控机理对进一步提高作物产量具有重要意义。近年来, 关于器官脱落机理的研究取得了显著进展, 研究结果表明, 植物各器官在脱落机制上具有保守性, 但不同物种间也表现显著差异。该文深入探讨了植物器官脱落的生理生化机制, 分析了不同环境因素的影响作用, 以及激素和酶在其中的具体作用, 旨在为作物遗传育种和农业生产提供坚实的理论支持和实践指导。

Abstract: The organs abscission is a phenomenon in which parts of organs are separated from the body. It is an adaptive strategy evolved by plants in the process of growth and response to environmental changes, which ensures the normal growth and adaptation of plants to the environment. This process involves the formation of abscission zones, activation of specific signals, cell separation, and is significantly regulated by its own physiological processes and external environmental factors such as light, temperature, and humidity. In agricultural production, the abscission of plant organs directly affects crop yield. Studying the regulatory mechanism of plant organ abscission is crucial for improving crop yield. In recent years, significant progress has been made in the study of organ abscission mechanisms. The results show that the mechanism of organ abscission in plants is conservative, but there are also significant variation among different species.This review will delve into the physiological and biochemical mechanisms of plant organ abscission, analyze the specific effects of different environmental factors, and the specific roles played by hormones and enzymes in this process. The aim is to provide solid theoretical support and practical guidance for crop genetic breeding and agricultural production.

Key words: organ abscission, abscission zone, molecular mechanism, enzyme, phytohormone
