It is a mechanism that helps prevent self-pollination and is most common among wind-pollinated and unspecialized insect-pollinated flowers, as in figwort.
是一种避免自花授粉的机制，在风媒花和非专性虫媒花中最为普遍，比方说玄参。
Protogyny in M. grandiflora lies in a mechanism that determines the anther dehiscence stage, thus reducing self-pollination and interference between pollen and stigmas.
广玉兰的雌性先熟是通过主动控制花药开裂时间，降低雌雄功能干扰，有效减少自花授粉。
We used gas chromatography to study the quantity of IAA and ABA in pear young fruits of different varieties from self-pollination to first physiological fruit-falling period.
采用气相色谱法对不同品种自花授粉后到第一次生理落果期梨雌蕊组织或幼果中的IAA、ABA含量变化进行了研究。
Few pollen grains of open flower self-pollination attached and germinated in the stigma of self-incompatible individuals, and intensive callose reaction occurred on the surface of stigma.
自交亲和系萝卜单株花期、蕾期以及自交不亲和系单株蕾期授粉后花粉多数能够正常萌发并穿越柱头进入子房。
Because the research was done on plants, some skeptical of the findings thought it came from cross-pollination even though the plants self-pollinate.
由于研究对象是植物，有人怀疑这是交叉传粉的结果(即便这些植物是自花传粉)。

Self-pollen tube growth could be promoted by treating stigma with CTX, but the pollen tube growth was inhibited by treating stigma with PTX before cross pollination.
CTX处理柱头后自花授粉对自花花粉管的生长具有促进作用；而PTX处理柱头后异花授粉，表现出对异花花粉管生长的抑制作用。

柱头上的平均花粉量为8— 2 1个，但多数为来自自花的花粉，散粉期花粉活力较高。
In addition, the analysis showed that the forced self-setting rate is lower than the free pollination.
另外，经分析可知，强迫自交的结实率比自由授粉的结实率要低。
