人工授粉

Maize inbreds are xenial. For the hybridization along with continuous gene exchange among different plants creating a new hereditary variation pool and thereafter on the effect of natural selection and artificial selection, it creates a new germ plasm which is different from the original germ plasm at quite a large extent.

玉米是异花授粉的，在不同植株之间，由于杂交以及相伴随的连续的基因互换会创造出新的遗传变异库，其后在自然选择和人工选择的作用下，产生在相当程度上不同于原始亲本种质的新种质。

The main results were as follows. Although the anthers dehisced totally at night, their pollens had already been matured when the petals were over half-opened at 8:00 am. Therefore, hand-pollination either in the morning or afternoon with this kind of pollens could increase fruit set.

结果表明，花药在傍晚自然裂开的花，其花粉在当天上午8时，花瓣呈超过半张开状态时，就已发育成熟，上午或下午人工提取这些花粉来进行授粉能提高坐果率。

The tomato adult plant has the vigor, the growth good pollen, can promote the pollen through the vibration or the undulation inflorescence to disperse from the anther sac, and falls to the column head on, thus achieves the manual supplementary pollination the goal.

番茄植株具有活力、发育良好的花粉，通过振动或摇动花序能促进花粉从花粉囊里散出，并落到柱头上，从而达到人工辅助授粉的目的。

Kernel filling, endosperm cell number and substance metabolism between apical kerenl and middle-basal kernel were analyzed and compared.

采用人工同步授粉法，分析比较玉米果穗上部和中下部籽粒灌浆、胚乳细胞数目及物质代谢方面的差异。

You didn't look closely. Actually, many of the flowers were synthetic and self-pollinating. They may be very beautiful, but they are poisonous.

妳是没有近看，其实很多花都是人工合成的，是自花授粉，漂亮是漂亮，但都有毒。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
