摘要
我国耕地资源紧张和优质饲草料严重短缺,利用盐碱地发展饲草产业既符合国家草牧业发展战略又能改变优质饲草料缺乏的局面.盐胁迫是重要的非生物胁迫之一,严重影响了植物的健康生长发育.了解盐胁迫对紫花苜蓿生长发育、产量及营养物质的影响有利于实现盐碱地资源的开发与利用,减轻日益增加的粮食压力.文中总结了盐胁迫对紫花苜蓿种子萌发、气孔导度及发芽状态等生理变化,探讨了盐胁迫对紫花苜蓿产量、碳水化合物、蛋白质含量的调控作用,并对今后的研究进行了展望.
Abstract
The shortage of arable land resources and high-quality forage materials in China has led to the de-velopment of forage industry on saline-alkali land,which not only conforms to the national strategy for forage hus-bandry,but also can change the situation of lack of high-quality forage.Salt stress is one of the important abiotic stresses that seriously affects the healthy growth and development of plants.Understanding the effects of salt stress on the growth,yield,and nutrient content of alfalfa is beneficial for the development and utilization of sa-line-alkali land resources,and can alleviate the increasing pressure on food production.This paper summarized the physiological changes of alfalfa seed germination,stomatal conductance,and germination status under salt stress,explored the regulatory effects of salt stress on alfalfa yield,carbohydrate,and protein content,and was looking forward to future research.
