Plants that are overexposed to light can produce weak stems because of low auxin levels.

这已经不堪重负光可以产生弱的植物茎，因为生长素水平低。

It has different types in different organs, it is transported basipetally in coleoptile and stem while acropetal transport occurs in root.

植物体内生长素的运输是一个需要能量的主动运输过程，它的极性运输是一个非常复杂的问题，在植物体的不同部位其运输方式也不同。

The biological activity tests show that some target compounds have a good activity as plant growth regulator, and N-5-(3-carboxy-1H-1,2,4-triazolyl)-N'-o- chlorophenylfonnyl urea, N-5-(3-carboxy-1H-1,2,4-triazolyl)-N'-o- bromophenylformyl urea, N-5-(3-carboxy-1H-1,2,4-triazolyl)-N'-p- methyl-phenyl formyl urea have excellent activity of auxin.

生测试验证明部分酰基脲类化合物具有良好的植物生长调节活性，其中N-5（3-羧基-1，2，4-三唑基）-N'-o-氯苯甲酰基脲、N-5-（3-羧基-1，2，4-三唑基）-N'-o-溴苯甲酰基脲和N-5-3-羧基-1， 2，4-三唑基）-N'-p(或m-甲基苯甲酰基脲具有优良的生长素活性。

Ribose/galactose/methyl galactoside importing ATP-binding protein 1 was participated in photosynthates transportation from leaf to grain in early and mid-stages.

分析结果表明，核糖／半乳糖／甲基半乳糖苷运输ATP结合蛋白l在灌浆前中期参与物质向籽粒的运输；生长素响应蛋内IAA27通过调节ATPase活性影响叶片物质运输；N-乙酰谷氨酸半醛脱氢酶在灌浆末期参与叶片的多胺代谢，延缓叶片衰老；谷胱甘肽S-转移酶和Cu/Zn-超氧化物歧化酶在籽粒灌浆后期的植物解毒和防御活性氧伤害中起着重要作用。

Four kinds of endogenous phytohormones in latex of Hevea brasiliensis were tested by using PGRIA and Gaseous Chromatogram.

采用酶联免疫检测技术和气相色谱法测定了巴西橡胶树胶乳中生长素、细胞分裂素、脱落酸和乙烯等4种植物生长物质的含量。

The trials were carried out in field experiment and artificial climate incubator. The sugar beet growth buds were treated at 1～3pairs of true leaves with gibberellin , autix , naphthaleneacetic acid and kinetin , and the plant growth regulating substances enhancing bolting of sugar beet in the first year and its doses were selected out. The sugar beet seedling induced by temperature and light were treated by abscisic acid , maleic hydrazide , uniconazole (S-3307) and paclobutrazol (PP333), and the plant growth regulating substances which make bolting reverse and their doses were screen out. The mechanisms of bolting and bolting reversing were discussed by examining the changes of endogenous hormones, activities of correlative enzyme to bolting, soluble protein, components of amino acid in the protein, components of fatty acid. The results were as follow

本研究通过田间试验和人工气候箱培养相结合的方法，在甜菜幼苗1~3对真叶时利用赤霉素、生长素、奈乙酸和激动素等生长调节物质处理茎生长点，筛选促进甜菜当年抽苔的植物生长物质及剂量；同时利用脱落酸、马来酰肼、烯效唑（S-3307）和多效唑（PP333）等处理经温光诱导当年抽苔的甜菜幼苗，筛选对当年抽苔逆转有效的种类和剂量，并通过测定内源激素含量、相关酶活性、可溶性蛋白质含量和氨基酸组分及脂肪酸含量及其组分的变化，探讨甜菜当年抽苔和抽苔逆转的机理，得到如下结论

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。
