Abstract
[Objective] The purpose was to study the mechanism of paclobutrazol mitigating drought stress of blueberry.[Method] Two southern highbush blueberry cultivars(Sharpblue and O′Neal) were used as materials to study the protective effects of 500 mg/L paclobutrazol on blueberry stressed by drought treatment.[Result] The results showed spraying aqueous solution of 500 mg/L paclobutrazol significantly alleviated the damages caused by drought stress.Pre-treatment of paclobutra201 decreased the level of relative conductivity,MDA content,contents of hydrogen peroxide(H2O2) and superoxide radical(O-2·),mitigated the decrease of photosynthetic rate,transpiration rate,relative water content and chlorophyll content under drought stress.[Conclusion] It indicates pre-treatment of paclobutrazol can increase the resistance ability of blueberry to drought.
