无性

Results The morphology and asexual reproduction of Cloudina are broadly similar to modern serpulid annelids and its flourishing is somewhat coeval and corresponding to a positive excursion of δ13C.

结果 Cloudina可能是多毛类龙介虫，二者在管体形态特征、无性繁殖方式等方面存在可比性；Cloudina的出现都对应着碳同位素的明显正漂移，具有基本等时的特点。

To achieve these goals, genetically-elite families, clones and hybrids produced by tree improvement and biotechnology programs will be planted and managed with intensive silvicultural systems.

为了完成这些目标，优良遗传基因、无性繁殖和杂交改进树木品种，以及生物工程项目，将会集中用于植树造林体系的种植和管理中。

Characteristics of colony, growth rate, t he shape and size of conidia were conducted. The morphological features of the isolates were similarly to Sphacelia sp..

这些培养特征及形态特征和麦角菌属真菌的无性世代麦角蜜孢霉属Sphacelia真菌类似。

Spinulosa was limited by the more than 2.0 meters water depth.

当水深超过2 m时，无性分株数明显减少，约为492株/m2。

Spinulosa decreased significantly when the water depth was more than 2 meters, as well as the sexual reproduction strategy of V.

随着水位的变化，有性繁殖体的投资比率发生变化，从水深1.4 m的2.77% 0.96%到水深2 m的0.13% 0.22%；而无性分株繁殖方式水深2 m以下没有显著差异。

In order to investigate the effects of different shading levels (Shading levels were: control 0, 50%, 80%, 90%) on the trade-off relations between sexual reproduction and clonal multiplication of Vallisneria spinulosa, a natural greenhouse experiment was carried out by winter tuber of Vallisneria spinulosa being collected from Poyang Lake in the Jiangxi Province.

以采自江西鄱阳湖的刺苦草冬芽为实验材料，在自然温室中经历了全不遮阳、部分遮阳等4种处理，研究不同遮阳处理产生的光线差异对刺苦草的有性繁殖和无性繁殖方式的资源配制的影响。

With increasing altitude,pollen numberdecreased and length of stylar ramification increased gradually.Increased stylarramification of plants of Saussurea with increasing altitude has importantadaptive significance of evolutionary ecology.It ensured sexsual reproductivesuccess,provided a foundation of hereditary variation and increased specificdiversity.In addition,asexsual reproduction of most species of Saussurea assuredindividual quantity.

根据我们调查，生活在青藏高原东缘的多数风毛菊属植物都具有无性繁殖方式，它保证了风毛菊属植物物种的个体数量，而花柱分枝的变长保证了风毛菊属植物的有性繁殖成功，为风毛菊属植物在该地区的进化提供了遗传变异的基础，增加了风毛菊属植物的物种多样性，使得风毛菊属植物的多数物种都成为该地区的常见种，也可能是青藏高原地区是风毛菊属植物的现代分布中心的原因之一。19。

Only known species of Cycliophora; lives symbiotically attached to a lobster's lip by an adhesive disk and feeding by means of a hairy mouth ring; its complex life cycle includes asexual and sexual phases.

通过带有粘性的圆盘附着共生在龙虾的唇边，通过带毛的嘴环进食；其复杂的生命周期包括无性繁殖和有性繁殖阶段。

Do you realize the consequences of an unconsummated royal marriage?

你有没有意识无性的皇室婚姻会有什么后果？

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
