种子

The coat protein gene of Cucumber green mottle mosaic virus was amplified by RT-PCR from total RNA of China import-based cucurbits seed and cloned into pMD18-T vector.

以直接从中国进口源性葫芦种子中提取的总RNA为模板，经RT-PCR扩增获得种子上携带的黄瓜绿斑驳花叶病毒(Cucumber green mottle mosaic virus， CGMMV)的外壳蛋白基因(LHP， Liaoning cucurbits seedprotein)，将其克隆到pMD18-T载体上进行序列测定。

I was sadly put to it for a Scythe or a Sicle to cut it down, and-all I could do was to make one as well as I could out of one of the Broad Swords or Cutlasses, which I sav'd among the Arms out of the Ship.

现在正是十一、十二月之间，即将收获大麦和稻子。我耕种和施肥的面积不大，因为，上面说过，我所有的种子每样只不过半斗，而又因第一次在旱季播种，把播下去的种子完全毁了。

In recent years, many studies have suggested that the selective pressure be-tween dispersers and plants is rather weak.

然而，食果动物和植物一对一的协同进化的例证并不多见；适合种子萌发和生长的环境在时空上难以确定；食果动物和植物的进化速度不一致；植物与种子传播者的选择压力存在着高度的不对称和不平衡，加上环境因素的重要影响，这种选择压力受到极大的限制而有可能变得不显著。

Drupes with one seed include plums and charries while many-seeded drupes include holly and elder fruits.

只含有一枚种子的核果有李和樱桃，而具多种子的有冬青和接骨木。

Flower buds not swollen at tip; drupes with 1 pyrene, normally 4-locular, 4-seeded or 3- or 2-seeded.

不使在顶部膨胀的花芽； 1果核的核果具，通常4室，或4种子以败育-2种子的或。

The method is based on a genetic model containing both the direct effects and maternal effects of an endosperm QTL and on an experimental design termed two-stage hierarchical design, in which the trait information is obtained from F3 endosperms and molecular marker information is obtained from F2 plants and F3 embryos.

文章提出了包括胚乳效应和母体效应的胚乳性状QTL定位的统计方法，该方法的实验设计是分子标记基因型信息来自F2母体植株和F3种子胚，胚乳性状表型值来自F3单粒种子胚乳，称之为两步等级设计。

Other eucalypts can grow new shoots after fire, but ash depends upon its seed supply to be cracked open by that fire and upon light from the sun in order to nurture the younger saplings.

它需要大火爆开它的种子壳，并让种子暴露在阳光下，使其发芽，长出幼苗。因此，这种桉树需要大火使森林变得通透，这样才有利于树木的再生。

The Global Seed Vault, opened this year on the far-northern Norwegian island of Spitsbergen, is a backup for the backups.

位于挪威远北岛屿斯匹斯伯尔根岛的全球种子库于2008年正式启用，形象地说，这个种子库将是将备份文件再次备份，以做到万无一失。

During the autumn of 2006, we investigated seed selection and digest time of Chinese ferret-badger, and discuss the selection effect of this animal.

于2006年秋季在后河保护区调查了鼬獾消化时间及其对枳椇种子的选择，并初步探究了鼬獾对枳椇的种子传播作用。

Four typical grassland communities, Stipa klemenzii, Stipa grandis, Leymus chinensis and Leymus chinensis + forbs, had been chosen along precipitation gradients from 200, 290, 350 to 450 mm respectively in Inner Mongolia Steppe. The objectives of this study were to determine the effects of grazing on plant community composition, aboveground and belowground biomass, species and functional group diversities and the relationship between diversity and productivity, the effects of grazing on soil seed bank species composition, seed density and diversity along the transect.

选取内蒙古草原三种主要草原类型(草甸草原、典型草原和荒漠草原)代表性群落羊草杂类草群落、羊草群落和大针茅群落、小针茅群落，应用样线法沿水分梯度研究放牧对内蒙古草原不同植物群落功能群组成、多样性、生产力以及多样性与生产力关系的影响和放牧对土壤种子库组成、大小以及多样性的影响，在此基础上，研究土壤种子库与地上植被间的关系。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
