The primary result reveals that the normal expression of Clone C103 is profoundly regulated by endogenous auxin in maize root tip, and the expression of Clone C103 maybe has some relationship with statolith in the periphery of central cap.

由此表明玉米根尖内源生长素影响根冠特定基因Clone C103的正常表达；Clone C103在根冠的表达位置推测该基因正常表达可能与中心根冠外周的平衡石有关。

It is important to further study the effects of low dose LaCl〓 on GH and thyroxine secretion and its mechanism.

进一步研究探讨小剂量氯化镧对甲状腺素和生长素调控轴路的生物学效应，阐明其作用机制，具有重要的理论和实践意义。

The results showed that there was a negative relationship between H2O2 content and CAT activity, thus H2O2 content was low when CAT activity was high. There was a close relationship between H2O2 content and differentiation process. H2O2 could be an important signal transduction factor during bud differentiation. IAA oxidase activity was decreased firstly, and then increased, which affected IAA oxidase and degradation pathway and regulate ratio of cytokinin and auxin. With differentiation process continuing, PPO activity was increased, which could cause browning or vitrifaction of seedling, or even malformation.

研究结果表明，鹅掌楸组培再生过程中，过氧化氢酶活性与H2O2含量变化呈负相关，CAT活性较高时，H2O2含量则较低。H2O2含量与鹅掌楸组培苗分化进程密切相关，H2O2可能作为信号因子在芽分化过程中发挥重要作用；IAA氧化酶活性呈现先下降后增加的变化规律，从而影响IAA氧化降解途径，调控细胞分裂素与生长素含量的比值，影响鹅掌楸芽的再生；PPO活性随培养时间的增加而升高，引起组培苗的褐变或玻璃化，甚至生长畸形。

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。

The results showed that MESC was used to treat micro-endosperm super-high-oil corn seed which could increase the content ratio of GA3 to ABA, the content of IAA and total soluble sugar content, and promote the metabolism of protein, oil and aminophenol during germination.

结果表明：微胚乳玉米种衣剂包衣可提高种子萌动时赤霉素(GA3)与脱落酸含量的比例，提高种子生长素和可溶性总糖的含量，促进蛋白质的形成和油脂的降解，加速氨基酸的利用。

NAA can replace apices to keep apical dominance but without to compete nutrient with tobacco leaves.

利用生长素进行烤烟钾素库源关系的生理调控，既保持了烟株的顶端优势，又不让其与烟叶竞争养分。

The name of different genotype of Arabidopsis seedlings is showed on the left of the figure.

图片下方数字表示使用生长素的浓度，左侧标注了拟南芥不同的基因型。

Generally it was in favor of fresh weight increased rate of callus of Ardisia spp to use 2, 4-D instead of using IAA or NAA, while the influence of auxin on dry weight increased rate of callus of Ardisia spp was connected with explants and auxin concentration used.

总体上生长素类使用2，4-D比使用IAA或NAA更有利于紫金牛属植物愈伤组织的鲜重增长，干物质积累则还因种和外植体以及激素浓度而异。

Brevicaulis was lower than that of A japonica, A. mamillata and A. crispa, when they were inoculated in the same rooting medium. The effect of NAA on shoot rooting of Ardisia was limited. The influence of NAA (0.5 mg/L) on sterile shoot rooting of A japonica, A. crispa and A. brevicaulis was poor when in comparison with IAA (0.5 mg/L) and IBA (0.3 mg/L or 0.5 mg/L), but it had no significant difference between NAA and other auxins on shoot rooting of A.

相同的根诱导培养基中，血党生根情况比虎舌红、紫金牛和百两金差；而生长素当中NAA对于诱导紫金牛属植物生根的效果不是很好，0.5 mg／L的NAA对诱导紫金牛、百两金和血党无菌苗生根的效应不如0.5 mg／L的IAA，0.3 mg／L和0.5 mg／L的IBA，对诱导虎舌红生根的效应则差别不大。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
