Abstract:
Taking ‘Rela No.1’ pepper seedlings as materials,different concentrations of paclobutrazol were adopted for analyzing the effect on the quality and physiological characteristics of ‘Rela No.1’ pepper seedlings.The results showed that 100~350 mg/L 15% paclobutrazol could effectively reduce plant height,increase stem diameter,reduce the leaf area,improve the root to shoot ratio,and significantly increase the activities of SOD and POD that were conducive to developing strong seedlings.200 mg/L 15% paclobutrazol was the most suitable concentration for developing strong seedlings.This study could provide scientific basis for regulating the growth of pepper seedlings and culturing strong seedlings through using paclobutrazol.
