繁殖

The regeneration way of bud clumps was adopted to establish a rapid technique system of propagation in Oncidium in this experiment.

笔者主要采用正交设计安排试验，探索通过以丛生芽途径再生植株的方法进行快速繁殖。

With eggs and children artemia were detedcted using nested-PCR. WSSV positive products could be detected in artemia, and DNA sequence of the product accords with the designed specific amplified one according to sequence analysis. The positive rates of wild brine shrimp and filial generation were 58% and 43%, respectively. However, it seems to be no regularity between parents and filial generations positive results. It may not judge whether WSSV could vertically transmit in artemia or not.

检测结果显示：卤虫中可扩增出特异性的、与引物设计吻合的DNA片段；DNA测序分析表明，扩增片段的DNA序列与白斑综合症病毒序列一致；野生卤虫携带白斑综合症病毒的阳性率为58％，实验条件下野生卤虫的后代的阳性率为43％；同一卤虫家系中，亲代与子代携带病毒的情况不完全一致，不能确定白斑综合症病毒可否通过繁殖在卤虫世代间进行垂直传播。

Therefore, it is theoretically possible to reproduce four offspring by using chromosomes in one oocyte.

因此， 从理论上讲用一个卵母细胞的染色体可能繁殖出4个子代。

Yolk forming stage didnt exist in workers. AR played an important role in oogenesis of termites.

表明雄激素受体在白蚁的卵子发生过程中有重要作用，工蚁和繁殖蚁在卵子发生的早期是相同的。

Follicle Stimulating Hormone and Luteinizing Hormone play a crucial role in the oogenesis and spermatogenesis of vertebrates.

可能调节繁殖蚁、兵蚁、工蚁的产生。这是首次证实FSH和LH在白蚁脑中的存在及分布，为揭示其在昆虫精子和卵子发生过程中的分子机制提供了直接证据。

This was the reason of no mature ovum in worker. But worker has a potential ability to turn into reproductives because of its complete differentiation stage and the growth stage in oogenesis.

由于具有完整的卵母细胞分化期和生长期，在巢群需要的情况下受调节可以进一步发育完成卵黄的形成，因此工蚁具有向繁殖蚁转化的能力。

Thefemale orangutan can first establish the relations with certainorangutans, but this kind of relations also is and reproductionsynchronization.

雌性猩猩会和某些猩猩优先建立关系，而这种关系也是与繁殖同步的。

Plant of the orchid family because commercial value is high and those who cause hill civilian and lover is excessive collect with manage, the one; that makes the main reason that orchid species is in severe danger on the other hand, because factitious development is a mountainous area, if give birth to the fell trees of selva to wait formerly, the destruction that causes zoology environment; is belonged to plus plant of the orchid family, planted distributinging belt is narrow, reach its oneself is progenitive and not easy, to living the environment asks to compare other plant slashing, make it becomes world biology to protect one of centers that organize an attention.

兰科植物由于商业价值高而引起山民和爱好者的过度采集与经营，成为兰花物种濒危的主要原因之一；另一方面，由于人为的开发山区，如原生热带雨林的砍伐等，引起生态环境的破坏；再加上兰科植物属、种的分布带狭窄，及其自身繁殖不易，对生存环境要求比其他植物苛刻，就使它成为世界生物保护组织注重的中心之一。

No steroids would be used on the Olympic pigs, which would be chosen from carefully monitored parents and only fed organically-grown feed, Mr Niu said.

牛胜难表示，奥运猪将选择受到严密监测的种猪母猪繁殖的猪仔，幷且只喂养有机饲料，不会对它们使用类固醇。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

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。
