摘要/Abstract

摘要：

水分是影响水稻生长发育的关键因素，探索水分高效利用机制对水稻生产至关重要。在植物生长发育过程中，根系会向周围环境分泌各类化合物，即根系分泌物。这些物质通过引发根际效应调控植物的生长与发育，是植物生长过程中不可或缺的部分。本文系统综述了根系分泌物的类型、生成途径及其在干旱胁迫下的生理响应机制，通过深入分析水稻根系分泌物在水分调控中的作用机理，指出当前研究中存在的问题，并对未来的研究方向提出建议。

Abstract:

Water is a key factor influencing the growth and development of rice. Exploring mechanisms for efficient water utilization is vital for rice production. During the process of plant growth and development, the root system secretes various compounds into the surrounding environment, known as root exudates. These substances regulate plant growth and development by triggering rhizosphere effects and constitute an indispensable part of plant growth process. This paper systematically reviews the types, biosynthetic pathways of root exudates, and their physiological response mechanisms under drought stress. By providing an in-depth analysis of the function mechanisms of rice root exudates in water regulation, this review identifies existing problems in current research and proposes suggestions for future research directions.

Key words: Rice, Drought stress, Root exudates, Rhizosphere environment
