授粉

Production is best with cross-pollination between types A and B. The flowers attract bees and hoverflies and pollination usually good except during cool weather.

生产是最好的交叉授粉类型之间的a ， b的鲜花吸引蜜蜂和hoverflies授粉通常不错，除在凉爽的天气。

Emasculation will probably be needed, and the pollen so obtained being used either in the pollen-mix or for dilution purpose

或许需要去雄，如此获得的花粉可用于混合授粉或稀释授粉。

Emasculation will probably be needed, and the pollen so obtained being used either in the pollen -mix or for dilution purpose

或许需要去雄，如此获得的花粉可用于混合授粉或稀释授粉。雄蕊长在花的中央，能产生花粉。

或许需要去雄，如此获得的花粉可用于混合授粉或稀释授粉。

In the late of April of the second year, male inflorescences unbound and pollinated. When female inflorescences accepted the pollen grains, ovary development was increased in early May. With the development of either of the two ovule, funiculus, integument and nucellus were differentiated. Embryo sac mother cell came into being and the meiosis begins. Then fuctional megaspore developed into matured embryo sac that contain eight nucleuses. In the end of May, double fertilization generated.

次年，4月下旬，雄花序解螺旋散粉，雌花序开花授粉；5月上旬，雌花序授粉后，迅速增长，子房膨大，两个胚珠分化出珠柄、珠被和珠心，珠心中产生孢原细胞；5月中下旬，大孢子母细胞形成并减数分裂，功能性大孢子形成成熟的八核胚囊；5月底，发生双受精。

Although the megagametophyte formed and even the double fertilization had been finished 70 days after pollination at normal temperature, the megasporogenesis had not yet been finished at low temperature.

低温(12-18℃)处理的蝴蝶兰，授粉50d开始分化胚珠原基、60 d胚囊处于大孢子母细胞时期，比常温(20-25℃)下的推迟10-15 d；授粉70 d，常温下的蝴蝶兰植株已完成雌配子体发育和双受精，而低温处理的蝴蝶兰仍未完成大孢子的发生过程。

The results showed that better ability of producation in the parthenocarpy line D-11 was observed without pollination. Its fruit weight, vertical and horizontal size were close to the fruit with pollination, and the fruit growth was faster than S8 line's.

结果表明：D-11品系在不授粉的情况下，仍具有较好的结实性能，其单果重和果实纵横径均接近于授粉后生长的果实，且比S8品系果实增重快、果重大。

Following characteristics of pollen germination and pollen tube growth were observed with fluorescence microscope.

用荧光显微镜对自交不亲和强度不同的梨品种丰水和菊水自花授粉及以丰水为母本的异花授粉后的花粉萌发及花粉管生长特性进行观察。

Of fruit are obtained on April 28 and May 26 4 week and 8 weeks after pollination,respectively

坐果数（1）和坐果数（2）分别表示授粉后4周（4月28日）和授粉后8周（5月26日）的调查结果。

In 2006 America's National Academy of Sciences released a report on the status of pollinators in North America that concluded "for most North American pollinator species, long-term population data are lacking and knowledge of their basic ecology is incomplete."

但事情的真相依然扑簌迷离。2006年美国科学院发布了一份关于北美授粉状况的调察报告，其结论是："对大多数北美地区的授粉动物而言，既缺乏长期收集的动物数量数据，也缺乏对其基本生态学的研究。"

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
