摘要/Abstract

摘要： 对平阴玫瑰(Rosa rugosa) 多酚含量及多酚氧化酶( Polyphenol oxidase, PPO) 活性与组培苗
生根的关系进行了研究, 对多酚含量、PPO活性与生根指数进行了相关性分析。结果表明: 平阴玫瑰不同
品种间的多酚含量、PPO活性及生根指数存在极显著差异。多酚含量与生根指数显著负相关, PPO活性与
生根指数极显著负相关。对不同pH条件下‘紫枝玫瑰’组培苗的PPO活性和生根指数的研究表明, ‘紫
枝玫瑰’组培苗的PPO活性及生根指数与pH均有密切联系, pH为6.5时PPO活性最高, 而生根指数最
低, pH 5.5最适宜生根。

Abstract: Polyphenol content, polyphenol oxidase ( PPO) activity and in vitro rooting ability of 5 Pingy
in rose (Rosa rugosa Thunb. ) cultivarswere investigated to seek for the physiologicalmechanism of rooting.
The results showed that polyphenol content, polyphenol oxidase activity and rooting index of different cultivars
were different significantly. According to analysis of correlation, polyphenol content, polyphenol oxidase activ
ity was correlated negatively to rooting index at P < 0.05 and P < 0.01, respectively. Polyphenol oxidase ac
tivity and rooting index of R1 rugosa Purp le B ranch at different pH conditions were also studied. The results
showed that both polyphenol oxidase activity and rooting index had significant correlation with pH, and the op
timal pH of PPO was 6.5, while the op timal pH of in vitro rooting was 5.5.

Key words: Rosa rugosa, Pingyin rose, Polyphenol, Polyphenol oxidase, Rooting
