Effect of Exogenous Chlorella vulgaris on Physiological Characteristics of Flue-cured Tobacco Seedlings Under Drought Stress
摘要
Abstract
To study the effect of exogenous Chlorella on physiological characteristics of flue-cured tobacco seedlings under drought stress,the tobacco variety'Zhongyan 100'was as the experimental material.The seedling of flue-cured tobacco was sprayed water as control(CK),and treated with drought(D),and was sprayed by 50(T1),100(T2),150 times(T3)of Chlorella vulgaris on the basis of drought treatment.The physiological characteristics of flue-cured tobacco seedlings under different treatments were compared.The results showed that the application of Chlorella vulgaris increased the antioxidant enzyme activity,soluble protein content,photosynthetic characteristics and chlorophyll content of tobacco,and decreased the content of malondialdehyde and proline decreased.T1 treatment had the best effect on promoting growth and development of flue-cured tobacco under drought stress.In conclusion,the application of Chlorella vulgaris could effectively alleviate the impact of drought stress on seedling of flue-cured tobacco.关键词
