授粉

Different contribution of the genes to starch biosynthesisLeaves and developing endosperms of Q319, C7-2, q404, ZN-A and S8 were used to study the expression patterns of 44 genes participating in starch synthesis. We found that ZmGBSSⅠ、ZmSSⅢ、ZmSBEⅡb、ZmBT2-2、ZmSh2-2、ZmSh2-3、ZmBT1 were expressed exclusively in the metaphase and anaphase of developing endosperm, and the expression patterns of ZmSUS1、ZmSus1L、ZmSUS3、ZmSSⅠ、ZmSSⅡa、ZmSBEⅠ、ZmISO1、ZmPul were consistent with the process of starch synthesis in the endosperm, while ZmUGP3 and ZmSUT2 were highly-expressed in all samples, suggesting that these genes perhaps devoted to starch synthesis in endosperm.

淀粉生物合成基因的不同贡献以Q319、C7-2、q404、ZN-A和S8自交系的幼叶、成熟叶、成熟子房、授粉后1d、5d、10d的种子和15d、20d、25d的胚乳为材料，研究了参与淀粉合成的44个基因的表达模式，研究发现ZmGBSSⅠ、ZmSSⅢ、ZmSBEⅡb、ZmBT2-2、ZmSh2-2、ZmSh2-3、ZmBT1在胚乳发育中后期特异性表达，ZmSUS1、ZmSus1L、ZmSUS3、ZmSSⅠ、ZmSSⅡa、ZmSBEⅠ、ZmISO1、ZmPul的表达在淀粉合成期显著上调，ZmUGP3和ZmSUT2在所有组织中高水平表达，说明这些基因可能主要负责胚乳淀粉的生物合成。

It begins to flower and fruit after being planted 2-3 years.Under nature pollination condition,the flowering rate of most tea plant varieties usually is very high.The flower bud differentiation of tea plant usually starts in June,lasts to December or even later.It takes about six months from bud differentiation to fruit.

茶树从花芽形成到种子成熟，共经过约一年半左右的时间，从6月到12月的6个月时间中，一方面是当年的茶花进行孕蕾、开花和授粉，另一方面是上一年受精的茶花发育形成种子并成熟的过程，两年的花果同时发育生长，都是大量消耗养分的生理和生长活动过程。

So we consider that increasing the fruit set rate in the early time were very important.

因此，生产中需要尽量保证前期花朵的成功授粉与结果。A.P。

The trees need protection from constant ocean or Santa Ana winds which may damage them and interfere with pollination and fruit set.

树木保护需要不断从海洋或圣塔安那风，可能会伤害他们的干扰授粉和坐果。

Characters of genetic diversity are followed Three allozyme loci AAT-3, PGD-1 and PGD-2 are monomorphic. The IDH-1 was silence in S.glauca but it was active in S. itlica and S. virids. Genetic diversity of green foxtail was more than that of most of other annual primary self-pollinated plant. The yellow foxtail was complex.

我国北方青狗尾草遗传多样性特征是：AAT-3、PGD在所有供试种源中均表现单态，金狗尾草与青狗尾草和谷子相比，IDH—1表现沉默，青狗尾草同其它一年生以自花授粉为主的植物相比表现更高的遗传变异性，金狗尾草表现为倍性复合体。

The possibilities of gene flow from wild Brassica juncea to transgenic glufosinate-and glyphosate-resistant gene oilseed rapes were studied by hand-pollination. The results demonstrated that the indexes of sexual compatibility of glufosinate-tolerant oilseed×wild B.

采用人工授粉的方法，分别以转基因抗草丁膦和抗草甘膦油菜为母本，野芥菜为父本，研究野芥菜的基因流动到转基因油菜中的可能性。

Add to this worries about long-term falls in the populations of other pollinators, such as butterflies and bats, and the result is a growing impression of a threat to nature's ability to supply enough nectar-loving animals to service mankind's crops.

蝴蝶和蝙蝠等其它授粉媒介数量长期下降的说法加剧了人们的担心。

其它授粉物种数量的不断减少加剧了这种担忧，比如蝴蝶和蝙蝠。

These advances are known as the sinsemilla techniques of production; sinsemilla, Spanish for without seed , are the dried, seedless female flowers of 大麻 plants which have been grown in the absence of males to ensure no pollination takes place.

这些新技术的产品就如同sinsemilla技术般知名；sinsemilla为西班牙的无种籽种植法，是让干燥无核的大麻花雌株生长在缺乏雄花来授粉的环境中。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
