摘要:

为研究外源小球藻对干旱胁迫下烤烟幼苗生理特性的影响,以烤烟品种‘中烟100’为试验材料,以喷施清水为对照(CK),分别设置干旱处理(D)及在干旱处理的基础上将小球藻稀释50(T1)、100(T2)、150倍(T3)后施用于烤烟幼苗,对不同处理下烤烟幼苗的生理特性进行比较。结果表明,施用小球藻后,烤烟幼苗的抗氧化酶活性、光合特性及可溶性蛋白和叶绿素含量均得到提升,丙二醛和脯氨酸含量下降,其中T1处理对于缓解干旱胁迫对烤烟的生长发育的效果最佳。综上,施用小球藻能有效缓解干旱胁迫对烤烟幼苗的影响。

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 Chlorellavulgaris 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.

Key words: Chlorella vulgaris, nitrogen fixation, drought, flue-cured tobacco
