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。

Stamens included; anthers ca. 1 mm. Style ca. 2 mm; stigma compressed globose.

雄蕊内藏花药长约1毫米花柱长约2毫米；柱头扁球状。

Ovary globose. Style equal to or slightly longer than stamens, equally or subequally 2-cleft at apex.

子房球状同样，等于或稍长于雄蕊的花柱或2半裂在先端。

Stamens as many as and opposite to perianth lobes, usually on the base of lobes; filaments filiform, short; anthers gynobasic or dorsifixed near base, 2-celled, parallel or divaricate, dehiscence usually longitudinal.

雄蕊与花被裂片对生并同数，通常位于裂片的基部；花丝丝状，短；花药着生子房基部或者靠近基部背着，2室，平行和极叉开，通常纵向开裂。

Morphology of sexual reproduction abortion in'High Noon', a distant hybridization cultivar of tree peonies(P.delavayi var. lutea×P. suffruticasa), was systematically investigated with light microscopy and cross. The results indicated that:(1)The stamens matured earlier than the gynoecia and pollens dispersed at the early stage of anthesis but the rate of normal 2-celled pollens were merely 2.41%.

采用光镜和杂交等方法对牡丹远缘杂交一代品种'正午'有性生殖败育进行系统形态学观察发现：(1)雄蕊较雌蕊先成熟，初花期即散粉，正常2-细胞花粉仅占2·41%，且花粉在多种培养液中、在自身和其它两种柱头上均不萌发；柱头在谢花期大量分泌粘液，进入最佳授粉状态；(2)同一胚珠中多个大孢子母细胞减数分裂高度不同步，胚囊发育与受精延迟，部分胚乳游离核在细胞化时期分裂异常；(3)自花及品种内异花授粉不结实，天然授粉结实率为0·053‰~0·130‰。

Male flowers: perianth tube basally solid; stamens 20, connectives completely united to form a stalked cup; anthers inserted on outside at base of cup, surrounding column base; gynostemium rudimentary.

雄花： 基部的花被筒实心；雄蕊20，药隔完全形成一个柄杯的；花药着生于在杯状的基部外边的，围绕柱状的基部；合蕊柱不发育。

Stamens 6-12, in 1 or 2 series; filaments adnate to ovary or style column with anthers free, or filaments and anthers fully adnate to style column to form gynostemium; anthers 2-loculed, dehiscence longitudinal.

或在1方面，雄蕊6-12系列；花丝贴生到子房上或者贴生到圆柱状花柱上，且花药离生，或花丝和花药与花柱合生形成合蕊柱。

Stamens 5 to very numerous, in 1-3 series, fused with the rudimentary pistil into a gynostemium or in bisexual flowers connate into a cylinder; free filaments absent; anthers 2-loculed, dehiscent longitudinally or by apical pores.

雄蕊5 到多，1-3 列，退化雌蕊愈合成合蕊柱或两性花合生成圆柱体无离生的花丝；花药2室，纵裂或者凭借顶孔开裂。

Stamens inserted below appendages; anthers ca. as long as to longer than filaments, base hastate.

在附属物下面着生的雄蕊；花药长约倍于到长比花丝，基部。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
