| 摘 要： | 对狗枣猕猴桃花芽分化的形态特征进行了观察。结果表明 ,狗枣猕猴桃花芽为混合芽 ,分化时期为当年的 3月中旬至 4月上旬 ,且具有分化时间短、速度快的特点。其形态分化可分为 5个时期 ,即未分化期、花芽分化始期、花被原基分化期、雄蕊原基分化期、雌蕊原基分化期。雌、雄花形态差异出现在雌蕊原基开始化时期。

| Abstract: | The morphological character of Actinidia kolomikta flower bud differentiation was observed in this paper.The results showed that Actinidia kolomikta flower bud belonged to mixed bud,and differentiated in the same year from the middle ten days of March to the first ten day period of April and have the feature of short duration and fast development.Its morphological differentiation could divided into four phases,that is the primary differentiation phase,flower primordium differentiation phase,staminal primordium differentiation phase and pistil primodium differentiation phase.The initial difference of morphological character between pistillate and staminate flowers emerged at the beginning of pistil primordium differentiation.$$$$ |
