| 摘 要： | 以牡丹(Paeonia suffruticosa)品种‘胡红’为试材,测定了不同发育时期花枝以及不同器官(花瓣、雌蕊、雄蕊、花托、花萼、茎、叶柄、叶)的乙烯释放量和ACC含量的变化。花的乙烯释放量变化类型主要取决于花瓣,花朵衰老时花托和雄蕊是乙烯释放的主要部位。雄蕊在初开期有一明显的乙烯释放高峰。花朵开放过程中花瓣的ACC含量缓慢减少,进入衰老期ACC含量又有快速上升的趋势;而茎的ACC含量一直处于下降趋势。叶柄和叶片的ACC含量在花朵的整个开放过程中变化不大。结果提示器官之间乙烯和ACC梯度在花朵开放和衰老前后起着重要的调节作用,而乙烯和ACC在花器不同部位间的运输及分配上有差异。

| Abstract: | Ethylene production rate and ACC content of peony(Paeonia suffruticosa)flower of cultivar'Huhong' were measured in eight different parts of peony flower,petal,pistil,stamen,receptacle,calyx,stem,petiole and leaf.The change pattern of ethylene production rate of intact flowers depended largely on petals.Receptacle and stamen were the main parts of ethylene production at the senescent stage.Peak of ethylene production rate from stamen occurred at the initial bloom stage.ACC content of petals decreased slowly ... |
