摘要
以临安雷竹为试材，对鞭侧芽发育为笋的过程中其外部形态和内部结构变化进行了研究，结果表明，雷竹鞭侧芽发育为笋可以划分为休眠期、萌动期、发育前期、发育中期、发育后期及出笋期。划分的外部形态指标为幼择的形态、颜色和芽的大小。内部结构划分的指标为节及节隔膜的分化与否，最大节隔膜之间的距离大小，细胞核的大小及有无，以及液泡的有无及大小。
With the Phyllostachys praecox in Linan, Zhejiang, We havestudied the morphology and the structure changes of the rhizomelateral bud developing into shoot,the results show that the development course can be divided into six stages: dormancy stage,germination stage,development stageⅠ,development stage Ⅱ,development stage Ⅲ and shoot stage.The morphological indexesare the morphology,the colour of the young sheath and the sizeof bud. The internal structure indexes are:the differentiation ofthe node and the node membrane,the distance between the largestnode membrances; the existence and size of the nucleusthe existence and size the vacuole.
