Spraying GA3 (40 mg/L) combined with 4-CPA(25mg/L), GA3( 100 mg/L) with CPPU (40mg/L) or GA3 (50 mg/L) with SM (150 mg/L) could improve the parthenocarpy of some flowers of Zaosu or Wujiuxiang pear variety after frost injury.

The results showed that there was a negative relationship between H2O2 content and CAT activity, thus H2O2 content was low when CAT activity was high. There was a close relationship between H2O2 content and differentiation process. H2O2 could be an important signal transduction factor during bud differentiation. IAA oxidase activity was decreased firstly, and then increased, which affected IAA oxidase and degradation pathway and regulate ratio of cytokinin and auxin. With differentiation process continuing, PPO activity was increased, which could cause browning or vitrifaction of seedling, or even malformation.
研究结果表明,鹅掌楸组培再生过程中,过氧化氢酶活性与H2O2含量变化呈负相关,CAT活性较高时,H2O2含量则较低。H2O2含量与鹅掌楸组培苗分化进程密切相关,H2O2可能作为信号因子在芽分化过程中发挥重要作用;IAA氧化酶活性呈现先下降后增加的变化规律,从而影响IAA氧化降解途径,调控细胞分裂素与生长素含量的比值,影响鹅掌楸芽的再生;PPO活性随培养时间的增加而升高,引起组培苗的褐变或玻璃化,甚至生长畸形。
