Pistillate flowers with stamens undeveloped or without pollen; disk often absent; ovary terete or obovoid; stigma capitate or discoid, sometimes 2- or 3-lobed, sessile.

雌花具不发达的雄蕊或没有花粉；花盘经常无；子房圆柱状的或倒卵球形；柱头头状或盘状，有时2-或3裂，无梗。

Pistillate flowers in dense spikes, without bractlets; calyx as in male flowers, persistent, recurved; rudimentary stamens very short; ovary with stigma capitate, sessile.

雌花在紧密的穗状花序里的，没有小苞片；花萼与雄花的相似，宿存，下弯；不发育雄蕊非常短；子房具柱头头状，无梗。

Pistillate flowers: calyx as in staminate flowers, persistent; corolla 4- or 5-lobed, base tubular and often inflated; reduced stamens absent; ovary sessile or with short pedicel, 1-loculed; ovules 2, pendulous from apex; stigma thick, peltate, apex concave, sometimes slightly oblique.

雌花： 花萼与雄花的相同，宿存；花冠4或5裂，基部管状和经常膨大；退化的雄蕊无；子房无梗或具短花梗，1室；胚珠2，从先端下垂；柱头粗，盾形的，凹的先端，有时稍的偏斜的。

The interval sowing experiments showed that 291S was a photo-thermo-sensitive male sterile line, which showed part fertile under short-day and low-temperature conditions when autumn sowing, showed high sterile under long-day and high-temperature conditions when spring sowing. The self-multiplication ability and sterility of 291S can be improved through selection effectively. The pistillody of stamens of 291S could be induced under certain photoperiod and temperature condition.

分期播种试验表明，291S是一种光温敏雄性不育系，秋播短日低温条件下表现为部分可育，春播长日高温条件下表现为高度不育，其可繁性和不育性经选择可以得到有效改良。291S在一定的光温条件诱导下会出现雄蕊心皮化现象。

But they were partial sterile, had 1～4 pollen sacs in each anther and had relative bigger petals and stamens at lower temperature situation. The RGCMS plants were complete sterile at the both temperature situations, and there was no pollen sac differentiation and had smaller peta...

表现核质不育的植株，在高温条件下，花瓣小，表现彻底的polCMS不育，无花粉囊的分化；在低温条件下，花瓣变大，也表现彻底雄性不育，具有核、质不育的共同特点，每个花药可分化出 1～ 4个花粉囊，但无可育花粉，其雄性败育时期和特点与S45A和 117A相同。

Morphological and cytological observations showed that the pol CMS plants in DGCMS Yi 3A were complete male sterile, had no pollen sac differentiation and had smaller petals and stamens at higher temperature situation.

花器形态和花药发育的解剖学观察结果表明，DGCMS-宜 3A中表现波里马细胞质雄性不育的植株，其花器形态和花药发育的解剖学特点与 pol CMS相同，即在高温条件下，花瓣较小，表现彻底不育，无花粉囊的分化；在低温条件下，花瓣变大，表现部分雄性不育，可分化出 1～ 4个花粉囊，并产生一定数量可育花粉。

Morphological and anatomical observations showed that the pol CMS plants in RGCMS?117A or RGCMS S45A were complete male sterile ,had no pollen sac differentiation and had smaller petals and stamens at higher temperature situation.

花器形态和花药发育的解剖学观察表明，RGCMS S45A和RGCMS 117A中表现波里马细胞质雄性不育的植株，其花器形态和花药发育的解剖学特点与polCMS相同，即在高温条件下，花瓣较小，表现彻底不育，无花粉囊的分化；在低温条件下，花瓣变大，表现部分雄性不育，可分化出 1～ 4个花粉囊，并产生一定数量可育花粉。

Stamens numerous, outermost whorl staminodial except in Pulsatilla kostyczewii; anthers yellow or purple, oblong, narrowly ellipsoid, filiform, or linear, with one longitudinal vein.

萼片5或6。花瓣无；雄蕊多数，最外退化雄蕊轮生除Pulsatilla kostyczewii外；花药黄或紫色，长圆形，狭椭圆形，丝状，或线形，具一纵向脉。

Stamens inserted in throat; filaments short, bases broad, connate, upper part narrow, free; anthers adnate to stigma head, apex acuminate, exserted; pollen tetrads in loose masses, 2 in each anther cell and fixed on 1 common retinaculum.

雄蕊着生于喉；花丝短，宽，合生的基部，狭窄的上半部分，离生；花药贴生于柱头头状花序，先端渐尖，外露；在松散的群众，每花药室2里的四合花粉和决定1普通retinaculum。

Methods: Five patients with parkinsonism or dystonia were assigned to general anesthesia using an modified endotracheal tube.

本实验依照人体实验之相关规定进行，五位患有帕金森氏症或肌张力异常的病人接受神经立体定位手术。
