甜菜耐盐性形态学、生理生化特性及分子水平研究进展

盐胁迫被认为是主要的非生物胁迫之一,对作物生长发育有着重要影响。甜菜具有一定的耐盐性,明确甜菜耐盐机理并加以利用,进而培育出耐盐性较强的甜菜新品种对高效利用盐渍化土壤具有重要意义。从盐胁迫对甜菜的形态学特征、生理生化特性及分子水平3个方面阐述了甜菜耐盐的研究进展,同时对当前耐盐研究存在的问题和今后可以进行的研究方向进行了探讨。

Research Progress on Morphology,Physiological and Biochemical Characteristics,and Molecular Level of Salt Stress in Sugar Beet

Salt stress is considered as one of the main abiotic stresses, which has important impacts on crop growth and development. Sugar beet has a certain level of salt tolerance and it is of great significance to further examine the salt tolerance mechanism of sugar beet and to make use of it for development of new sugar beet varieties with strong salt tolerance for efficient cultivation in saline soil. In this paper, the research status of sugar beet's salt tolerance was discussed from three aspects: morphological characteristics, physiological and biochemical characteristics, and molecular level. At the same time, the existing problems and future research directions of salt tolerance were discussed.
