果树低磷胁迫研究进展

Research Advance on Low Phosphorus Stress of Fruit Trees

如何提高植物磷利用效率和筛选耐低磷标题品种已成为研究热点。本文综述了对果树低磷胁迫下的磷吸收、转运和分配,果树低磷胁迫下的光合作用变化,以及果树对低磷胁迫的响应机制包括形态响应机制、生理响应机制、分子响应机制等方面的研究进展,并展望了今后果树低磷胁迫的研究方向。

Improving phosphorus use efficiency of plant and screening low phasphorus tolerant varieties had become a hot spot of research.This article reviewed the absorption,transport and distribution of phosphorus,the photosynthesis in low phosphorus stress of fruit trees,summarized the morphological response, physiological response, and molecular response in low phosphorus stress of fruit trees, discussed the future research prospects in low phosphorus stress of fruit trees.
