干旱胁迫下5个烤烟品种的生理指标变化及抗旱性比较
Physiological Changes and Drought Resistance Comparison of 5 Flue-cured Tobacco Cultivars under Drought Stress
摘要
Abstract
[Objective] To study the drought resistance of 5 flue-cured tobacco cultivars.[Method] Five flue-cured tobacco cultivars were selected and cultured by using floating seedling-raising technology.And they were treated with drought stress at 5-leaf period of seedling.And some physiological indices related with drought resistance were determined.[Result] Under the same conditions of drought stress,the sensitivity and tolerance of some flue-cured tobacco cultivars to drought had significant difference.The drought resistance of Anyan 2 and Zhongyan 14 was similar,belonging to flue-cured tobacco cultivars with stronger drought resistance.The drought resistance of Yunyan 97 and Zhongyan 100 followed by,and the drought resistance of K326 was the most worst.[Conclusion] The results can provide reference for selecting main varieties of flue-cured tobacco in arid areas.关键词
