Abstract

Abstract: To learn how the fiber-synthesis re,dated by plant growth resistors,excised pea seedlings (Pisum sativum L．) were treated with gibberellic acid(GA)，ethylene or abscisic acid(ABA)．rI1le fiber level in the seedlings uauy increased after harvest and it was further enhanced by ethylene or ABA，and reduced by
GA，whereas，activities of related emymes(phenylalanine deaminase, polyphenol oxidase，cinnamyl alcohol dehydmgenase and pemxidase) in the seedlings were enhanced by treatment with ethylene or ABA，However cinnamyl alcohol dehydmgenase activity was significantly reduced by GA．

Key words: Pea, Fiber systhesis, Gibberellic acid, Ethylene, Abscisic acid
