花粉

With the pollen germination and pollen tube growth temperature was 25℃, the best culture time for 60 min.

培养时间为60min时，花粉萌发和生长较好。

Two patterns of Arabidopsis pollen tube oscillatory growth were detected by using this device.

观察发现，体外生长的拟南芥花粉管存在两种振荡生长方式。

Through the method, complete active pollen tube mitochondria is obtained, and the mitochondria separating and purifying efficiency is improved.

采用本方法获得完整的具有活力的花粉管的线粒体，提高了线粒体分离纯化效率。

Pollen tube growth oscillates in rate. The underlying mechanisms that control oscillatory growth have been unknown.

极性生长的花粉管表现出振荡式生长的特性，但其机理还不清楚。

By the means of grinding,sperm cells were released from pollen tube.

采用研磨法从花粉管中分离精细胞。

Therefore, the suitable stage for foreign DNA introduction through the pollen tube pathway should be after flowering.

因此，利用花粉管通道导入外源DNA的适宜时期可能在开花后。

The results show that chemical treatments may be a way of changing germination and tube growth of pollen in Vaccinium ashei.

改善环境条件和化学处理是提高花粉萌发率的有效途径。

As one of the key modulators of the actin organization, profilin has been shown to be essential in the polar growth of the plant cells such as pollen tube and root hair cells.

Profilin作为一种微丝骨架的超分子结构和功能的关键调节因子，己被证明在花粉管和根毛细胞的极性延伸中起重要作用。

The invention relates to a method for separating and purifying mitochondria in a pear pollen tube, and belongs to the biotechnology field.

本发明涉及一种梨花粉管中分离和纯化线粒体的方法，属于生物技术领域。

To improve the efficiency and application, pollen tube growth of different Brassica species is observed and factors of transformation are studied for optimization.

继而通过比较不同白菜型油菜、甘蓝和甘蓝型油菜品种的花粉管生长规律和转化率，得到表达报告基因的除草剂抗性植株，实现了不同类型和基因型油菜的高效转化，扩展了方法的应用范围。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
