烤烟品种幼苗低温反应敏感度与其生化差异性研究
The Difference of Biochemistry and the Sensitivity to Low Temperature in Flue-Cured Tobacco Varieties
摘要
Abstract
Flue-cured tobacco varieties with different chilling tolerance, such as Zhongyan100, NC82, K326, were treated with 2℃, 5 ℃ and 8℃ at 5th-leaf stage. The sensitivity to low temperatures of flue-cured tobacco varieties were investigated according to the biochemical indexes, such as relative electrical conductivity, MDA, Peroxidase activity, Proline content and so on. The results demonstrated that, relative electrical conductivity, Peroxidase activity, MDA content and Proline content all obviously rise under the low temperature stress; In all the three tobacco varieties, the low temperature sensitivities are higher under 2℃ and 5 ℃, and the most under 2℃ treatment of 3 days, the least under 8℃ treatment of 7 days.关键词
