Effect of GA3 Treatment on Postharvest Lignification of Bamboo Shoot

Abstract

Abstract: Effects of different concentration gibberellic acid(GA3) on postharvest lignification and quality of bamboo shoot under 4 ℃,85%～95% RH were studied in this paper.The results showed that GA3 treatment significantly inhibited the increase of lignin and fiber contents in bamboo shoot during storage,decreased the contents of H2O2 or O2 and the activities of phenylalanine ammonia Lyase(PAL) or polyphenol oxidase(PPO).It was also found that GA3 treatment retarded the increase of malondialdehyde content and kept better qualities of bamboo shoot.100mg/L GA3 was better than 50mg/L GA3.

Key words: bamboo shoot, GA3, lignification
