A review of progress in response to fruit trees under water stress

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.
