摘要:

通过对皮层组织、凯氏带、维管柱等根系主要解剖组织结构在逆境条件下发生的一系列适应性变化进行综合论述,揭示植物根系通过调节甚至改变自身结构特征以应对各种逆境,提出今后应从逆境条件变化的角度开展植物根系解剖结构的形态可塑性研究,同时结合形态、解剖及生理代谢指标,建立抗逆性品种筛选指标体系。

Abstract: This paper reviews the adaptive changes of main anatomical structures of root system including cortical tissue, casparian strip and vascular cylinder under stress conditions, and reveals the responses of the roots to different stress conditions by selfadjustment and even alternation of structure. It is suggested that future research should be conducted to investigate the plasticity of root anatomical structure under different stress conditions. In addition, index systems of screening stressresistant varieties should be established by combining morphological, anatomical and physiological metabolic parameters of plants.
