细胞分裂素

No callus could be induced from leaf or petiole explants of varieties F30 and Ⅱ cultured on MS medium if supplemented alone with 6-bezyladenine （6-BA） or thidiazuron, or kinetin. However, the calli were induced on MS medium containing 2.0 mg L-1 6-BA and 0.5 mg L-1 NAA （α-naphthaleneacetic acid）, and the calli derived from petioles of variety Ⅱ could produce redifferentiated shoots, but of variety F30 could not. The later could only produce shoots directly from the base of the petioles.

将品种F30和Ⅱ的叶片和带叶叶柄接种到含不同浓度单一细胞分裂素（6-BA、TDZ、KT）的MS培养基上培养，均未能诱导出愈伤组织，而在含2.0mgL-1 6-BA＋0.5mgL-1 NAA的培养基上可以诱导出愈伤组织，且由品种Ⅱ叶柄诱导产生的愈伤组织可再分化出芽，品种F30诱导的愈伤组织却不能分化，但在其叶柄基部可直接出芽。

Boron is one of the essential nutrients for plants and B deficiency induces a series of physiological changes, including the release of lateral bud. In the present study, the mechanism about the B deficiency-induced apical dominance was studied in pea plants Pisum sativum L.

cv。 Lisa为主要试验材料，研究缺硼减弱顶端优势和诱导侧芽生长的机理、生长素和细胞分裂素在顶端优势中的重要作用以及两者之间的相互作用。

Endogenous hormones, including gibberellin (GA4), indole acetic acid, isopentenyl adenine and abscisic acid, were analyzed during bolting in spring radish (Raphanus sativus L.).

采用酶联免疫吸附法测定了春萝卜抽薹过程中顶端生长点处嫩叶的赤霉素(GA4)、生长素、细胞分裂素和脱落酸等含量的变化情况。

We propose that dexfenfluramine can also inhibit hypoxia-induced pulmonary vascular remodeling via SERT activity and inhibition of hypoxia-induced p38 mitogen-activated protein kinase.

因此我们认为右旋酚氟拉明也能通过改变SERT的活性抑制缺氧诱导的肺血管重构和抑制缺氧诱导的p38细胞分裂素活化蛋白激酶

Thiadiazole ; acyl urea; acyl thiourea; synthesis; plant growth regulating activity; auxin activity; cytokinin activity

1； 3； 4-噻二唑；酰基脲；酰基硫脲；合成；植物生长调节活性；生长素活性；细胞分裂素活性

Growing regulation of ten kinds of plant under different communities is that the plant grows fast in the nutrition stage and reaches the maximum in the heading stage, thereafter the growing velocity slackens gradually.

在恢复演替过程中，生长素和赤霉素一直保持相对稳定；细胞分裂素经历了由单峰型曲线→双峰型曲线→单峰型曲线的转变过程；而脱落酸经历&突变&后趋于稳定。

So acertain concentration of auxins is important to the induction of embryonic callus, and cytokinins are cooperative in the process of somatic embryo genesis and embryoid growth.

因此，一定浓度的生长素是诱导紫叶酢浆草胚性愈伤组织的关键因素，细胞分裂素在体细胞胚的发生和发育过程中起增效作用。

So a certain concentration of auxins was important to the induction of embryonic callus. Cytokinins were cooperative in the process of somatic embryo genesis and embryoid growth.

因此，一定浓度的生长素是诱导紫叶酢浆草胚性愈伤组织的关键因素，细胞分裂素在体细胞胚的发生和发育过程中起增效作用。

Cytokinins move through the plant less readily than auxins or gibberellins and appear to move in opposition to auxins—from root upward to shoot, not shoot downward to root.

细胞分裂素不像生长激素或者赤霉素那样容易移动，看起来他们和生长激素移动的方向相反——从根部到芽，而不是由芽到根部。

Comparing with BA,0 1 mg·L -1 TDZ was more effective in inducing germination and development of buds,regenerating prolific caespitose buds via organogenesis,promoting rhizogenesis and improving acclimation efficiency.

Mok等[2 ] 首次发现TDZ有很强的细胞分裂素活性，浓度很低的TDZ能促进利马豆愈伤组织生长。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
