Efficient methods of vegetative propagation and improved screening techniques are also required.

高效率的无性繁殖法和改良的鉴定技术也属必需。

These are inherent and apparently permanent and can be propagated vegetatively.

这些具有内在的和明显的遗传性，并可以无性繁殖。

All theses studies established a base for transforming Acer negundo gene, had important value for cloning aceraceous and other plants.

为复叶槭的基因转化奠定了基础，对槭树科其他树种的无性繁殖和遗传改良具有重要参考价值。

A multinucleate mass of cytoplasm formed by the aggregation of a number of amoeboid cells, as that characteristic of the vegetative phase of the slime molds.

But if that theory is correct then bdelloid rotifers, freshwater invertebrates that haven't had sex in at least 30 million years, should have been parasited into extinction long ago.

但是如果这个理论是正确的，那么蛭形轮虫（一种淡水无脊椎动物，它已经无性繁殖至少3000万年了）应该在很早以前就被寄生虫消灭了。

But if that theory is correct then bdelloid rotifers, freshwater invertebrates that haven't had sex in at least 30 million years, should have been parasited into extinction long ago.

但是如果这个理论是正确的，那么蛭形轮虫，这种至少已经存活了3千万年的无性繁殖的淡水无脊椎生物，应该早就因为感染寄生虫而灭绝了。

Few creatures—even bacteria—do without sex entirely, but bdelloid rotifers are among that minority.

很少有生物是完全的无性繁殖，连细菌也不是，但蛭形轮虫却属于这个少数群体。

Regeneration and reproduction by establishing tissue culture system of Betula halophila may be a promising way.

植物组织培养技术发展异常迅猛，本研究旨在建立濒危植物盐桦的组织培养再生系统，并对该盐桦组织培养再生系统进行了优化筛选，该研究为盐桦的种质资源保存和无性繁殖开辟了一条行之有效的途径。

From above, fine genetic resources of asexual reproduction had been found from commercial and bivoltine genetic races.

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
