In this paper, the biological characteristics of florescence, spikelet and inflorescences structure, morphogenesis formation of inflorescence, megasporogenesis and the development of female gametophytes were studied systematically by using anatomy structure, scanning electron microscopic and paraffin section methods. The results were as followed:(1) Phyllostachys praecox was the bamboo flowering fragmentarily; the cultivation changed the characteristic of flowering; the plantlets of flowering were complex and splitted into three kinds: the plantlet flowering before continued flowering; the plantlet flowering before stopped flowering and the plantlet changed into flowering. The inflorescence of Ph. praecox was indefinite inflorescence or called false inflorescence, and actually it was flower stress structure. Its basal unit was pseudospikelet with two kinds: apical spikelet and lateral spikelet. The floret had one lemma, one pelea, three stamens, one pistil and three lodicules.

本研究综合运用形态解剖学、扫描电镜、石蜡切片等技术手段，对雷竹花期生物学特性、小穗与花序构造、花序形态建成过程、大孢子发生与雌配子体发育等进行了较为系统的研究，结果表明：(1)雷竹为零星开花竹种，耕作条件对其开花特性具有重要影响；开花植株类型复杂多样，可以分为以前开过花现在继续开花、以前开过花现在停止开花以及以前未开过花现在转为开花等3种类型；雷竹花序为无限制花序或称&假花序&，实为花枝结构，基本单位为&假小穗&；假小穗有顶生和侧生之分；小花具内外稃各1枚，雄蕊3，雌蕊L，另具3枚大小不等之鳞被。
