Ovary ovoid or globose; stigmas 2 or 3 (-5), usually recurved, papillate throughout.───子房卵球形或球状；柱头2或3(- 5)，通常下弯，整个具乳突。
the meantime, other social stigmas may also be playing a part in the increasing cases.───此同时，其他的社会污点也可能在这些增加的病例当中扮演一部分角色。
Pollination is the mechanical transfer of pollen from the anthers to the stigmas.───授粉是机械地把花药里的花粉传送到柱头上去。
sometimes she asks me to hear her telling stories about "girls who bring stigmas to family"───有时她又会让我坐着听她讲有关“带给家庭耻辱的女孩”的故事。
After a flower has been open for a time the anthers and stigmas may come together allowing selfing if there has been no cross-pollination.───花开放一段时间后，如果不能异花受粉，它的花药和柱头就可以接触进行自交。
There was corresponding relation between the developmental process of female gametophyte and the color status of stigmas.───雌配子体发育进程与雌花柱头颜色状态存在一定的联系。
stigmas slightly flat at top, narrowly margined on lateral sides, shortly beaked in front, beak erect, with a smaller stigma hole at tip.───柱头稍平在顶端，在在前面的侧的边，具短喙，具喙的直立，具小的柱头孔在顶部上的狭边缘。

The great impact of the differences of the receptible period of stigmas and pollen viability between the two species on effective pollination and seed setting rate is discussed.
Ovary ovoid or globose ; stigmas 2 or 3(-5), usually recurved, papillate throughout.
Monterey's transpiration of pistils and stigmas are lowest.
Dichogamy The condition in which the anthers and stigmas mature at different times thus helping prevent self-pollination. Compare homogamy. See protandry; protogyny.
In most heteromorphic plants the stigmas of the different morphs have different surface textures and the pollen may be of different size or sculpturing or both.
The sterile plant with multiple stigmas had a high outcrossing percentage of seed setting because its multiple and long stigmas enlarged the area of pollination.
Placentas parietal; stigmas numerous, sometimes 2-fid or flabellate .
Protogyny in M. grandiflora lies in a mechanism that determines the anther dehiscence stage, thus reducing self-pollination and interference between pollen and stigmas.
