柱头

BJ-1A has a uniformed population with stable agronomic characters, a complete male sterility with 100% of male sterile plants, a high natural stigma exsertion rate (3%~38%) and out-crossing rate (45%~65%), and a high combining ability.

BJ-1A群体整齐，农艺性状稳定，不育株率和不育度100%，异交性状好，花时集中，柱头自然外露率33%~38%，异交结实率45%~65%。

Compared with no spurting GA3, spurting GA3 could promote the stigma length significantly, but reduce the stigma exsertion rate、the angle of grain husk、the outcrossing rate and seed production significantly or extremely significantly.

与未喷施赤霉素相比，喷施赤霉素后，雌蕊长度显著增加，柱头外露率、颖壳张开角度、异交结实率和制种产量均极显著降低。

Compared with 810S,the total photosynthetic pigment content of Biao 810S was aabout 50%lower;which was the main cause of the yellow green leaf.2、The spikelet numbers,stigma exsertion rate and flowering time of Biao 810S were same as that of 810S.There were no significant difference of the agronomic traits between the the cross combination which came from the maintainers D100 and R96-1 and the combination from 810S.3、The photosynthetic rate of Biao810S was higher than 810S under strong light and lower under weak light.

叶绿素含量下降是标810S叶片呈淡黄绿叶色的根本原因。2、标810S的颖花数、柱头外露率和开花时间与对照基本相当，与恢复系D100和R96-1配制的杂交组合农艺性状与用810S配制的相应推广组合无明显差异，表明标810S可替代810S应用于两系杂交水稻，其淡黄绿叶色性状可应用于杂交制种田的不育系群体除杂，同时可根据幼苗期淡黄绿叶色性状植株的比例用于鉴定杂交组合中不育系的混杂率。3、弱光条件下标810S的光合速率低于810S，强光条件下标810S光合速率比对照高，且标810S在光强2400μmol·m~(-2)·s~(-1)以下没有光饱和点和"午休"现象。

Ovary 3-loculed; ovules 2 per locule. Style filiform; stigma small.

子房3室；每室2胚株花柱丝状柱头小。

Fruit a berrylike indehiscent drupe with pyrenes 2 × as many as styles, globose, in dried material characteristically longitudinally angled, squarish or rectangular in longitudinal cross-section, with flattish apex and base, contracted or not at equator, disk persistent at base, style or stigma remnants persistent at apex.

果浆果状的不裂的核果的，具果核数为花柱的2倍，球状，在干标本上明显具纵向的角，纵向截面近似方形的或长方形的，具平的先端和基部，收缩或在赤道轴上不收缩，花盘宿存在基部，花柱或柱头残余在先端宿存。

Pingbianensis flowers were ants (Aphaenogaster smythiesii Forel,Formicidea), springtail (Hypogastrura sp., Hypogastruridae, Collembola) and one species of beetles (Anomala corpulenta Motsch, Rutelidae). These pollinators generally have restricted movement capacities and hence promote geitonogamy or mating between individuals in close proximity within populations. The results of out crossing index pollination experiments in our study suggest that T. pingbianensis has an animal-pollinated, mixed selfing and outcrossing breeding systems.

通过对屏边开口箭的开花物候、传粉生物学、交配系统的研究以及对近交衰退的检测，结果显示：屏边开口箭单花花期约15天左右，柱头、花粉活力持续时间较长；传粉昆虫多为蚂蚁、跳虫，偶有小甲虫拜访，缺乏长距离传粉昆虫；杂交指数以及套袋试验的结果表明屏边开口箭为高度自交亲和的混交模式植物，且在幼苗早期并没有表现出明显的近交衰退现象。

Ovary superior, 2-carpellate, coherent, 1-loculed, rarely 3-5-loculed; ovules 2, rarely 1 per locule, pendulous from apex, anatropous with abaxial raphe and micropyle facing upward; funicle usually thickened above micropyle; style rarely developed, simple; stigmas 2(or 3-5), or coherent to capitate or peltate.

子房上位，具2心皮，合生，1室，很少3-5室；子房每室2（很少1）胚珠，从顶端下垂，倒生，背面有种脊，珠孔向上；珠柄通常在珠孔上部加厚；花柱很少发育，单一；柱头2(或3-5)，或者合生成头状或者盾形。
