细胞分裂素

Its main features are: algae body as a single cell or even into a variety of groups; cell walls composed of silica and pectin, but also by the structure of the shell and the shell under the combined set of the Cheng, vertical section view was "soap-box"-shaped; in the upper and lower shell surface of the shell are patterns arranged in patterns on both sides of the main mode of symmetry and radial symmetry is divided into two categories, for the classification of the most important basis; be able to campaign Type in the shell has a shell side seam, can not be changed no shell seam types; pigment body sheet or ribbon, 1 or 2, or for multiple small discoid, yellow green or brown, containing chlorophyll a, c, also contains fucoxanthin and silicon A flavin and other photosynthetic pigments; storage material mainly for oil droplets; reproduction mainly for cell division and cell division in diatoms obvious features are: each cell division, resulting from two sub-cells,, only one and the mother cell and so big, the other one is smaller.

其主要特征是：藻体为单细胞或连成各式群体；细胞壁由硅质和果胶质组成，而且在结构上都是由上壳和下壳套合而成，纵断面观呈"肥皂盒"形；在上下壳的壳面上有花纹，花纹排列的方式主要分为两侧对称和辐射对称两大类，为分类上的最重要依据；能运动的种类在壳面都有壳缝，不能动的种类均无壳缝；色素体片状或带状，1个或2个，或为多个小盘状，黄绿色或黄褐色，含叶绿素a、c，还含有墨角藻黄素和硅甲黄素等光合色素；贮藏物质主要为油滴；繁殖方式主要为细胞分裂，硅藻的细胞分裂的明显特点是：每次细胞分裂所产生的2个子细胞中，仅有1个和母细胞等大，另1个则稍小。

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。

When optimal levels of growth substances, particularly auxin and cytokinins, are utilized, many species of gesneriads can be generated from a single leaf.

当生长调节物质，尤其是生长素和细胞分裂素的含量适宜时，某些苦苣苔在3～4个月内可由一片叶子再生1000株以上的小植株。

These results showed that B directly involved in the polar auxin transport process.5. Under control condition, decapitation resulted in the rapid increase of cytokinins concentrations in the shoot and the release of lateral bud of pea pl

对缺硼的豌豆植株去顶也可以导致细胞分裂素水平的增加，但变化的幅度明显小于对照条件下的变化，表明由于缺硼影响了激素的水平从而减弱了顶端优势。

The roots and leaves of the four reed ecotypes were determined for thelevels of abscisic acid and cytokinins using an enzyme linked immunosorbent assay throughout the whole of growing season.

采用酶联免疫吸附法，测定了整个生长季节四种芦苇生态型根和叶组织中脱落酸和细胞分裂素含量的变化。

Applying B to the 2nd node of B deficient pea plants increased the IAA concentration and export from the shoot apex, and resulted in the establishment of apical dominance.

与此相比，对缺硼的豌豆植株第2节处供硼和CPPU后明显促进了侧芽的生长，说明细胞分裂素对侧芽生长的促进作用只有在供硼的条件下才能表现出来。

Mature and immature embryos of maize inbred line 87-1 were used as explants and calli were induced and cultured on improved N6 medium. The method of enzyme-linked immunosorbant assay was employed to detect endogenous contents of abscisic acid, indoleacetic acid, gibberellins (GA3) and cytokinins of immature, mature embryos and their calli during culture process.

以玉米自交系87-1的幼胚和成熟胚为材料，采用酶联免疫法测定了不同培养时间诱导的幼胚及成熟胚愈伤组织内源脱落酸、吲哚乙酸、赤霉素(GA3)和细胞分裂素含量的动态变化。

The methods of enzyme-linked immunosorbant assay were employed to detect endogenous contents of abscisic acid, indoleacetic acid, gibberellins (GA3, GA4) and cytokinins of immature embryos, embryonic and non-embryonic calli during culture process.

酶联免疫法测定不同培养时间后未成熟胚，以及由此诱导的胚性和非胚性愈伤组织，内源脱落酸、吲哚乙酸、赤霉素(GA3、GA4)和细胞分裂素(DHZR、IPA、ZR)含量。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
