花粉

Any of numerous chiefly North American weedy plants constituting the genus Ambrosia that produce highly ''.

北美洲任何构成豚草属的植物，有变应原的花粉，治疗花粉热和气喘。

The new materials(N/BBCC and J/BBCC) and their transmigration parent put up the similar phenotypes in development stage,morphological characters,POD enzyme activity,and so on.But differences in male fertility,proline content and relative conductance rate were existed among them,in which the development of androecium in N/BBCC was abnormal,showing serious male sterility,and the proline content and relative conductance rate in N/BBCC and J/BBCC were much lower than their transmigration parent,C/BBCC.

两个新材料及其轮回亲本C/BBCC在生长发育时期、植株外部形态特征、POD酶活性等方面表现基本一致，但在雄性育性、脯氨酸含量及相对电导率上存在着明显差异，其中N/BBCC雄蕊发育不完善、花药瘦小、药内花粉量很少且多为无生活力的畸形花粉，表现严重败育；J/BBCC和N/BBCC的脯胺酸含量及相对电导率明显低于其轮回亲本C/BBCC。

The results were as follows. Pollen pretreated with 0-4 ℃ low temperature could abort the inducing stage that androgenesis needed, but most pretreated pollen (93.6%) still kept vigor when abortion occurred, and the frequency of callus differentiation reached 1.33%. On the contrary, most unpretreated pollen degenerated and died.

结果表明：0~4℃的低温预处理花药1d，花粉可以完成其进行雄核发育所需要的诱导过程，而且绝大部分花粉(93.6%)仍然保持存活，花药分化率达到1.33%；而未经预处理的花药在诱导过程完成时，大多数退化死亡。

With basic liquor,wild thorn pear juice, bee pollen and flavouring as the materials,the processing technology for nutritional juice containing alcohol was explored through orthogonal experiments,and the wall-breaking of bee pollen was studied.

用基础酒、野刺梨果汁、蜂花粉、香精为原料，通过正交实验，探索含酒营养果汁饮料的生产工艺；并对蜂媒花粉的破壁工艺进行了探讨，实验可知花粉用曲霉培养，在pH5.4、温度55℃、10%NaCl降解56h，破壁率达98.5%以上；由基础酒降度实验可知：用1.35mg/100ml海藻酸钠和180mg/100ml可溶性淀粉联合处理20°加浆酒，18h可沉淀完全，除去大部分高级脂肪酸酯。

Results: a total of 9 189 pollens had been collected during summer and autumn in this area.

结果：共收集该地区夏秋季空气中飘散花粉9 189粒，4层楼顶与7层楼顶空气中花粉种类和含量相差不大，17层楼顶空气中花粉种类和含量减少。

The pollen dispersion time has close correlation with the density change of pollens in the space.

其结果在不同的立地条件和不同气候条件下、花粉分散时间与空间花粉密度的变化密切相关。5月16至19日为花粉散出的高峰，时散粉量集中在每日10时至14时。

Pollen has to travel from the stamens, where it is formed, to the pistils, where it is needed.

花粉必须从产生花粉的雄蕊转移到需要花粉的雌蕊上去。

If you suffer from hay fever , wear sunglasses to stop pollen getting in your eyes , avoid going outdoors when the pollen count is high often included in TV and radio weather reports , and dona ?

如您患有花粉症，磨损墨镜停止花粉获得在你的眼睛，避免在户外时，花粉计数高通常包括在电视及电台的天气报告

If you suffer from hay fever, wear sunglasses to stop pollen getting in your eyes, avoid going outdoors when the pollen count is high (often included in TV and radio weather reports), and dont mow the grass or lie on freshly cut grass.

如您患有花粉症，磨损墨镜停止花粉获得在你的眼睛，避免在户外时，花粉计数高（通常包括在电视及电台的天气报告），以及don 吨mow基层或躺下就新鲜削减基层。

Such results indicated that isolation distance could be an effective way to minimize crop-to-crop gene flow in rice.

5在实验条件下，花粉源的大小对基因漂移频率的影响不显著，这可能和供体花粉密度随与花粉源距离的增加而迅速衰减有关。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.
