Tumefaciens mediated transformation using cotyledonary node as explants was optimized; 3 methods including cutting chapiter, ovary injection and chapiter spreading for pollen tube pathway was compared. Cutting chapiter and ovary injection can both achieve insect resistant gene tranformants.

优化了以子叶节为外植体的农杆菌介导转化技术；比较了切割柱头、子房注射和子房涂抹3种花粉管通道法处理授粉后黄瓜子房的转化效果，切割柱头和子房注射均可成功获得黄瓜抗虫转基因植株。

The chartreuse circle three inches in diameter is dotted with 23 seed holders and ringed by immature pollen sacs.

那直径达三英尺的黄绿色的花芯上点缀着二十三粒花籽，并被未成熟的花粉囊包围着。

Cherry Picker, Oregon, 1992Bushels of ripe cherries spring forth from trees pollinated by honeybees.

图为从前面的樱桃树上摘下的大量的成熟的樱桃，这些樱桃树是经由蜜蜂传授花粉的。

Pollen as the target for gene transfer is a potential plant transformation system which can avoid the problens of somaclonal variation and chimaera resulting from in vitro regeneration.

以花粉作为外源DNA的媒介，获得转基因植株是有潜力的遗传转化体系。它可避免离体培养过程中的遗传变异和转基因植株的嵌合现象。

A honeybee forages for pollen among cineraria flowers in Alpes-Maritimes in southeastern France.

一只蜜蜂为牧草花粉中的菊花卉在阿尔卑斯滨海省，在法国东南部的。

A honeybee forages for pollen among cineraria flowers in Alpes-Maritimes in southeastern France. Alpes-Maritimes is home to Grasse, a flower-strewn medieval town known for the past two centuries as the perfume capital of France.

意译：一只蜜蜂为植物传受花粉正在菊花之上，这是位于法国东南的阿尔卑斯山，一种菊花点缀那中世纪的小镇而闻名于过去两个世纪，就像今天的法国的首都巴黎的香水那样出名。

The approaches for decreasing the gene flow include chloroplast transformation, pollen sterility, seed sterility, cleistogamy, apomixis, temporal control, and transgenic mitigation.

目前降低外源基因扩散的方法主要有叶绿体转化、花粉不育、种子不育、闭花受精、无融合生殖、暂时性控制及转基因缓和等。

Experts remind that mother to infant bedding drying, clothes drying under a tree not as much as possible, to recover the shells hit you, and may be coated with pollen, dust, insects and other small debris out shells.

专家提醒，妈妈为婴儿晒被褥、衣服时尽量不要在树下晒，收回时要弹打一下，把可能沾上的花粉、粉尘、小虫子等杂物弹掉。

In Brassica, codominant relationships are more frequent than dominant and recessive ones in both the stigma and the pollen, as one characteristic of SI in Brassica.

在柱头和花粉中，自交不亲和等位基因之间的共显性关系要比显性和隐性关系更加普遍，这是芸薹属自交不亲和性的一大特点。

Both of them, to be codominant markers, can identify false hybrids not only from selfed seeds of male and female but also from foreign pollen and mechnical contamination.

两引物均能在父母本中扩出特异带，为共显性标一记，不仅能够鉴别杂交种中混杂的母本自交的种子和父本的种子，还可鉴别部分由于外来花粉或机械混杂等造成的假杂种。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
