| Abstract: | Objective]The research aimed to study the drought resistance of sugarcanes in 28 regional trials of Guangxi.Method]The natural drought symptoms and the recovery situation after rewatering were compared,and the difference drought resistance of 28 sugarcane varieties with high yield and sugar content at the early growth stage in the area trails of Guangxi were compared and analyzed by 8 different physiological indicators and cluster analysis method.Method]The results showed that among 28 sugarcane varieties using the areas trials of Guangxi,there were 6 varieties with highly resistant,8 varieties with moderately resistant,13 varieties with non-resistant.7 different physiological results by cluster analysis were basic accordance with the results the natural drought symptoms and the recovery situation after rewatering.Conclusion] The study can provide reference for extend and application of good sugarcane varieties. |
