Effect of Magnesium Deficiency on Physiological Characteristics of Strawberry

Seedlings of the‘Hongyan’cultivar of strawberry were used as materials,the effects of magnesium deficiency on physiological characteristics were studied by hydroponically test.The results showed that magnesium deficiency reduced the height of seedling,the length of root,the area of leaf and weight of strawberry;the relative conductance and the contents of MDA were increased,the content of chlorophyll,the activity of SOD and POD were decreased.The contents of reducing sugar was increased while the sucrose was decreased,but the total soluble sugar was increased.Magnesium deficiency stress could therefore declined the quantum of life-form of strawberry,and declined the activity of enzyme,induced the damage of cell membrane,as well as lowered the capacity of ROS scavenging system.
