细胞分裂

Cytokinins are produced in roots, where they stimulate cell division.

天然的细胞分裂素是腺嘌呤的衍生物。

Existence of cytokinins in regeneration medium had no effect on increasing the regeneration frequency.

分化培养基中添加细胞分裂素不能提高再生频率。

Crispa. The influences of cytokinins on callus growth were related to explants.

细胞分裂素对朱砂根的愈伤组织生长的影响与外植体有关。

Resulting from our experiments show that cytokinins,especiallyzeatin,is very important to sustain root system activity and leafphysiology.

试验表明根源细胞分裂素是维持根系及地上部生理活性的重要机制，其主要成分是玉米素。

Also unlike auxin, cytokinins promote the growth of lateral buds, not shoot tips.

同样不同于生长激素，细胞分裂素促进侧芽的生长，而不是顶芽的生长。

Cytokinins are important plant hormones and can delay plant senescence .

细胞分裂素是一类重要的植物激素，它可在一定程度上延缓植物的衰老。

Like most plant hormones, cytokinins also have other effects, including the prevention of leaf aging, or senescence .

如同大多数植物激素，细胞分裂素很有其他功效，包括阻止叶片老化或衰老。

The effects of some media and concentration of 2,4-D on callus-induction with 6 kinds of Turfgrass seeds and 2 kinds of Turfgrass calli,and 3 sorts of cytokinins on callus differentiation were studied.

以6种草坪草种子和2种草坪草愈伤组织为材料，研究了基本培养基种类和2，4-D浓度对愈伤组织诱导以及不同的细胞分裂素对分化的影响。

If the trees were simply cut down, cytokinins would accumulate in the roots and signal the tree to sprout new shoots.

如果树木被简单地削减，细胞分裂素会积聚在基层和信号的树木发芽的新枝。

It has been suggested that cytokinins and small GTP_binding proteins might be the switch of JA and SA signal ing pathways.

茉莉酸信号转导途径和水杨酸信号转导途径存在着交叉，小GTP结合蛋白和细胞分裂素可能起着信号开关的作用。

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。
