Abstract:
Taking ‘Xiangye’ strawberry as the test material, the effects of three types of saline-alkali stress on the growth and physiological characteristics of strawberries under different concentrations of neutral salt, mixed saline-alkali and alkaline salt were studied by using pot cultivation, in order to provide reference for the promotion and planting of ‘Xiangye’ strawberry in saline-alkali land in central and northern Henan.The results showed that by increasing leaf biomass, the root biomass of strawberry reduced, root activity and the osmotic regulation substances accumulated inside body was improved, the activity of antioxidant enzymes to withstand low concentration salinity-alkalinity stress was enhanced, but with the stress concentration increased, MDA content in strawberry increased, the victim was aggravating, root activity reduced, some lower osmotic regulation substanced content, antioxidant enzyme activity was restrained.The biomass of each part decreased.Among the three types of salt and alkali, alkaline salt caused the most harm to strawberry, mixed salt and alkali followed, and neutral salt was the least.
