| 摘 要： | 根系是土壤-植物进行物质和能量交换的中间体,是作物吸收水分和养分的重要器官,同时也是一些内源激素的合成器官,对植物适应营养胁迫有非常重要的作用。根系生物学已成为一个新兴的研究领域,越来越引起人们的重视。本文利用现有文献,结合本研究室的部分相关工作,简要综述了低磷胁迫时作物根系的形态学反应。主要包括根系分化与发育增强、菌根增多、根构型改变、光合产物分配的变化等。

| Abstract: | Root is the medium of soil and plant for substance and energy exchange,and it is also the main organ of plants to absorb water and nutrients and synthesize hormone.So,it is important for plant to adapt nutrient stress.Root-biology is a new and promising research field,to which researchers home and aboard attach more and more importance.This article making full use of publications related to plant suffering from low-P stress and combining with some results in our laboratory,reviews some Morphological variety of plants tolerant to lowP tress briefly,including the root development promotion,fungus increase,root architecture changes,and carbohydrate partitioning etc. |
