边坡先锋植物多花木兰的抗旱性
Drought Resistance of Slope Pioneer Plant Magnolia multiflora
摘要
Abstract
Objective] The aim was to reveal response of M.multiflora to soil drought stress.[Method] Using pot water controlling method to simulate drought conditions,photosynthesis,physiological index of M.multiflora were determined.[Result] Results showed that there was no sig-nificant influence on Pn of M.multiflora under mild drought stress.There was a significant decrease in moderate and severe drought stress,and the drought stress led to Gs,Tr,Ci significantly decreased,the Pn,Gs,Tr,Ci decreased 61.04%,86.27%,87.77% and 42.63% compared with the control group.With the aggravation of drought stress,the MDA in M.multiflora leaves was not significantly increased in mild drought, the Pro and soluble sugar of M.ultiflora content increased with the drought stress,the content of Pro and soluble sugar were 8.06 times and 3.16 times than the control groups under severe drought.[Conclusion] M.multiflora has a strong draught tolerance,and is suitable for growing in the conditions of mild drought habitats,and M.multiflora can be considered as the key plant in terms of vegetation restoration in hydropower engi-neering slope.关键词
