红砂幼苗对PEG胁迫下外源NO的生理生化响应
Physiological and Biochemical Responses of Red Sand Seedlings to Exogenous NO under PEG Stress
[目的]红砂(Reaumuria soongorica)属于超旱生小灌木,具有耐旱、抗逆性强等特点,适于生长在干旱半干旱地区,因其具有防风固沙的能力,常用于维持荒漠生态系统的稳定性,对植被的恢复具有重要意义。但是由于极端气候频发,红砂的荒漠植物群落面临着退化或大面积死亡的风险,因此提高红砂抗旱能力是一项重要举措。外源一氧化氮(NO)可以促进植物生长发育,在植物的抗逆性调节中应用十分广泛。聚乙二醇(PEG)是一种大分子聚合物,能够夺取水分,从而对植…查看全部>>
[Objective]Red sand(Reaumuria soongorica)belongs to the super arid small shrub,which has the characteristics of drought resistance and strong stress resistance.It is suitable for growing in arid and semi-arid areas.Due to its ability to prevent wind and fix sand,it is commonly used to maintain the stability of desert ecosystems and is of great significance for vegetation restoration.However,due to the frequent occurrence of extreme weather,the desert plant c…查看全部>>
