Abstract:
Taking ten pepper cultivars such as ‘Shuaixianhong’ and ‘Zhejiao Zaoshucusheng Xinyidai’ as test materials,different concentrations (0%,2.5%,5.0%,7.5%,10.0%) of PEG solutions were used to simulate drought stress.The effects of PEG drought stress on the drought resistance of 10 pepper cultivars at germination stage were investigated,in order to provide reference for the pepper production.The results showed that low concentration of PEG 6000 improved seed germination of ‘Shuaixianhong’ and ‘Fengkang No.2’；low concentration of PEG 6000 improved the radicle and plumule elongation in all cultivars.Under drought stress,the drought resistance index and germination stress index of some cultivars decreased with the increasing of PEG concentration,while there was no significant change in cultivars such as ‘Fengkang No.2’ and ‘Zhejiao Zaoshucusheng Xinyidai’,which were obtained by using the membership function analysis.The order of drought-resistance of the ten kinds of Capsicum frutescens tested cultivars was ‘Fengkang No.2’>‘Wangtianhong No.3’>‘Chaobandun’>‘Zhejiao Zaoshucusheng Xinyidai’>‘Tiansheng Xinyidai’>‘Shuaixianhong’>‘Shengnihong’>‘Luoyan No.9’>‘Hongsheng Xinyidai’=‘Luoyan 2017-2’.According to its comprehensive evaluation value was divided into three categories,‘Fengkang No.2’‘Wangtianhong No.3’‘Chaobandun’‘Zhejiao Zaoshucusheng Xinyidai’ were drought-resistant varieties,‘Tiansheng Xinyidai’‘Shuaixianhong’ and ‘Shengnihong’ were medium drought-resistant varieties,‘Luoyan No.9’ ‘Hongshengsheng Xinyidai’ and ‘Luoyan 2017-2’ were weak drought resistant varieties.
