不同甘蔗品种对干旱和复水的生态生理响应
Eco-physiological responses of different sugarcane varieties to drought and re-watering
摘要
Abstract
[Objective] The present study was conducted to study the eco-physiological effects of drought and re-watering on 6 sugarcane varieties in order to provide reference for the drought resistant sugarcane breeding and cultivation. [ Method ]Six sugarcane varieties were grown in greenhouse by using artificial water control. The agronomic traits and physiological parameters of different sugarcane varieties were investigated to evaluate the drought tolerance and recovery ability after re-watering. [Result]All the agronomic traits and physiological parameters showed different variation patterns at different drought and rewatering times in various varieties, but they were all recovered after re-watering. The order of drought resistance for the 6 sugarcane varieties from strongest to weakest was arranged as follows: GT28>ROC22>GF98-296>GT21>B8>ROC16, and the order of recovery ability for the 6 sugarcane varieties during re-watering after drought was arranged as follows: GT28>ROC22>B8>GF98-296>GT21>ROC16. [Conclusion]Green leaves per plant, cell membrane permeability and chlorophyll contents, soluble sugar, and MDA could be used as important drought resistance indexes for different sugarcane varieties. GT28, ROC22, and GF98-296 displayed better drought resistance than the new variety B8, which showed general drought resistance with fertility performance after drought ROC 16 showed the weakest drought ability and recovery ability.关键词
