Abstract

Abstract: Excised green asparagus（Asparagus officinalis L.） were treated with gibberellic acid（GA3）at 24℃±1℃. The results indicated the levels of lignin, total phenol and active oxygen in asparagus treated with GA3 were significantly lower than those of in the control. Activities of the enzymes related lignin synthesis，including phenylalanine deaminase, polyphenol oxidase, cinnamyl alcohol dehydrogenase and peroxidase were also reduced by GA3 treatment. Degradation of protein，DNA and RNA in the asparagus were significantly inhibited by GA3 treatment. The results suggested that GA3 treatment could improve the postharvest quality of green asparagus.

Key words: Green asparagus, Gibberellic acid, Lignification
