【摘要】 甜菜碱是目前研究最多,也是最有效的相溶性物质之一,可以提高植物对低温、高温、盐、干旱、重金属等非生物胁迫的耐性。本文结合多年来甜菜碱提高植物在非生物胁迫下的抗逆性、与其对植物光系统的保护作用及甜菜碱促进植物生长发育的作用机制等研究进展进行综述。甜菜碱在提高植物的抗逆性及促进植物生长发育研究方面具有广阔的应用前景。更多还原

【Abstract】 Glycinebetaine(GB) is one of the organic compatible solutes that can accumulate rapidly in many plants under salinity stress, drought, low temperature, high temperature and enhanced the tolerance to adverse conditions. This review focuses on improvement of GB on stress resistance for plants, protecting the photosystem and promoting the development and growth of plants. GB has broad application prospects for improving plants resistance and promoting the development of plants.更多还原
