棉花GA 20-氧化酶基因的克隆和功能分析
5.Comparing the difference in the modes of action between brassinolide and auxin, gibberellin, it has been proposed that the signal transduction pathway of BR is different from those of other plant hormones.
通过比较油菜素内酯与生长素、赤?素促进生长作用方式的异同，提出油菜素内酯促进生长的信号传导路径不同于其它植物激素。
6.Endogenous indole-3-acetic acid(IAA),gibberellin 1 and 4(GA_(1+4))and abscisic acid(ABA)have been studied during the fertile transformation of photoperiod sensitive genic male-sterile rice(PGMR)Nongken 58S.
运用免疫检测技术测定了光敏核不育水稻(PGMR)农垦58S 育性转换过程中内源吲哚乙酸(IAA)、赤霉素(GA_(1+4))与脱落酸(ABA)含量的变化.
7.The changes of contents of indole 3 acetic acid (IAA), gibberellin (GA 3), zeatin nucleotide (ZR), isopentenyl adenine (iPA) and abscisic acid (ABA) in young spikes of wheat were investigated, and the relation of endogenous hormone contents in young spikes to floret development was analysed.
在不同群体条件下 ,测定小麦幼穗发育过程中生长素 (IAA)、赤霉素 (GA3)、玉米素核苷 (ZR)、异戊烯基腺苷(i PA)和脱落酸 (ABA)含量的变化动态 ,分析小麦幼穗内源激素含量与小花发育的关系。
8.After the Si-Mo heteropoly acid was forined in 0.2mol/L H_2SO_4 medium,it could be reduced to Si-Mo bule by gibberellin in a very wide pH range. The maximum absorption is at 810nm. The molar absorptivity is 3.51×10.4L·mol??-1?·cm??-1?.
在0．2mol／LH2SO4介质中生成硅钼杂多酸之后，赤霉素能在相当宽的酸度范围内将其还原成十分稳定的硅钼蓝，其最大吸收波长为810nm，表观摩尔吸光系数为3．51×104L·mol－1·cm－1。
9.The contents of indoleacetic acid(IAA),gibberellin 1+3(GA 1+3),isopentenyladenosine group(iPAs),zeatin riboside group(ZRs) and dehyro zeatin riboside group(DHZRs) decreased under the stress of acid rain, while abscisic acid (ABA) content increased, and the ratio of inhibitive substance ABA to incentive substance IAA,GA 1+3 went up. The cellulase activity also enhanced after acid rain stress. These caused the high dropping of young fruits.
酸雨胁迫后 ,龙眼幼果IAA、GA1+ 3 、ZRs、DHZRs、iPAs含量下降 ,ABA含量升高 ,生长抑制物ABA和生长促进物(IAA、GA1+ 3 )的比值提高 ,酸雨胁迫还使纤维素酶活性上升 ,促进幼果脱落 .
