植物生长素

Auxin is one of the most important plant hormones in that it regulates almost all aspects of plant growth and development.

生长素是最重要的植物激素之一，参与了植物生长发育的各个方面。

Auxin plays an essential role in signal transduction pathways of plant hormones.

生长素是一类重要的植物激素，它与植物生长发育的许多过程相关。

With emphasis on effects of auxin and brassinosteroid on development of plant cell and tissues; related

主要进行植物激素作用机理和植物功能基因组学研究。研究方向集中于生长素和油菜素内

Similar to S-adenosylmethionine decarboxylase(B26),S-adenosylmethionine methyl-transferase(B70), allene oxide synthase(B38),ethylene receptor(B96),cytochrome P450(B58) and methionine synthase (B77) were found in ovaries of Pingyi Tiancha at 1d before the blossom day,which related to plant hormone and could participate in metabolic pathways of ethylene,polyamine,jasmonate acid and gibberellin,et al.,as well as had close relationship with maturity and senescence of plants.

在平邑甜茶开花前1d的子房中发现的S-腺苷甲硫氨酸脱羧酶(B26)、S-腺苷甲硫氨酸甲基转移酶(B70)、丙二烯氧化合酶(B38)、乙烯受体(B96)、细胞色素P450酶(B58)、甲硫氨酸合酶(B77)等相似基因片段与植物体内的生长素有关，将会参与乙烯、多胺、茉莉酸、赤霉素等的代谢途径，与植物的成熟和衰老具有密切的关系。

Our observations with transgenic plants showed that the PF40 gene affected the growth of lateral shoots developing in the basipetal pattern early after floral transition.

测量结果表明PF40基因过量表达的转基因谷子生长素的含量降低为对照的0.6～0.8倍，而细胞分裂素的含量较对照约升高0.2～0.35倍，生长素与细胞分裂素的比值在转基因植物中改变明显，降低到对照的一半。

In this paper, we studied seasonal variation of endogenous IAA、 GA_3、ZR and ABA content of Leymus chinensis、 Agropyron michno、 Stipa grandis、 Cleistogenes sguarrosa、 Koeleria cristata、 Carex korshinskyi、 Allium bidentatum、 Artemisia frigida, Kochia prostrate and Potentilla acaulis in different restoring succession stages, which were determined by ELISA in the growing season in 2005. At the same time we recorded the phenological development and growing regulation of each kind of plant.

本文于2005年生长季，对处于不同恢复演替阶段的羊草、米氏冰草、大针茅、糙隐子草、草、黄囊苔草、双齿葱、冷蒿、木地肤和星毛委陵菜十种植物，运用酶联免疫吸附法，测定内源生长素、赤霉素(GA_3)、细胞分裂素和脱落酸含量的季节动态，同时记录每种植物的物候期和生长规律情况。

The proper concentration of SNA for canning pine-apple in 100ppm. High concentration of SNA also decrease the storage life of fruit and cause rot. Therefore, it is not recommended for fresh pine-apple for export, except in case of spring fruit, 50 ppm of SNA will improve the peel color and with no adverse effect on storage of fruit.

SNA在凤梨果实发育中期处理时，采果后果实之贮藏力减低且易腐烂，尤以处理之浓度愈高者愈甚，故为提高鲜凤梨之品质及贮藏力，应禁止用植物生长素处理为原则，但50ppm低浓度处理有增加果皮色之效果，且对品质及贮藏力之影响亦小，为提高凤梨春果之外观，勉强可使用。

The photophysical property of the complex is investigated by means of IR spectra, Raman spectrum and laser excited, high-resolved luminescence spectra which indicates one kind of Eu site with local symmetry of C 2v in the complex.

合成了植物生长素对氯苯氧乙酸和 1，10 邻菲罗林与铕的三元配合物Eu 3·Phen 。对所合成化合物进行了元素分析和热谱分析。通过测定配合物的红外光谱、拉曼光谱和激光激发高分辨荧光光谱研究了配合物的光物理性质。荧光光谱表明配合物中Eu离子只具有一种化学环境，Eu格位的局部对称性是C2v

The results showed that mild alkali stress (pH 6.0~6.5) promoted plant growth, while severe high pH inhibited both seed germination, photosynthesis and root elongation.

结果表明：pH值过高会抑制种子萌发；随着pH值的逐渐增加，根的相对生长量和幼苗叶绿素含量均呈现先增加后减少的趋势；同时，根尖生长素含量随着pH值升高呈现先增加后减少的趋势，表明生长素含量变化可能在植物对碱胁迫的响应中，尤其是在根伸长过程中起着重要作用。

D (2,4-dichlorophenoxyacetic acid) A synthetic AUXIN used as a potent selective weedkiller.

2，4－二氯苯氧乙酸：是一种合成的植物生长素。

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。
