Abstract: The progress of recent research in response to fruit trees under water stress is reviewed. The morphological reactions and microstructure changes in leaves and roots of fruit trees under water stress are described. Some physiological and biochemical indexes of fruit trees, such as stomatal reactions, photosynthesis, variation of water potential, metabolism of carbohydrates, plant mineral nutrition, metabolism of lipoxygenase and polyamine, changes of endogenous phytohormones, and contents of proline and betain, are summarized in this paper.

Key words: fruit trees, water stress, response

摘要： 综述近十多年果树对水分胁迫反应的研究进展。对果树在水分胁迫下叶片、根系的形态和显微结构的变化以及气孔反应、光合作用、水势变化、碳水化合物代谢、矿质营养、活性氧代谢、多胺代谢、内源激素、脯氨酸和甜菜碱等生理生化指标的反应作了全面的阐述。
