无性繁殖

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。

Its the best model tree specie in forest engineering genetic breeding, So it has many advantages, such as smaller genome, easier to propagate and operate than many other tree species through traditional and molecular methods.

由于其基因组小，有性和无性繁殖容易，在传统和分子操作上要比大多数树种简单，所以它是林木基因工程育种的理想模式树种。

Such rootstocks or cultivars were reproduced true to type by vegetative propagation .
