Experimental result showed that under the wavelength of 460 nm,there was good linear relation between absorbency and content of SO42-;and stationary time that absorbency value needed became longer along with the increase of sample quantity of phosphoric acid.When absorbency become stationary,there is good linear relation between the phosphoric acid sample quantity and the content ofSO42-.So the content of SO42- can be adjusted by turning the sample quantity to make it in scope of standard curve.
实验结果表明,在波长为460 nm处,硫酸根含量与吸光度成良好的线性关系;随着磷酸取样量的增加,吸光度达到稳定值所需的时间相应增加,稳定后磷酸取样量与硫酸根含量成良好线性关系,因此实验过程中可通过调整磷酸的取样量来调节硫酸根含量,使之在标准曲线的测定范围内。

The results showed that coverage, tiller density, turf quality, leaf chlorophyll and water content declined markedly along with turgidity under the persisting stress of heat and drought. Compared with mid-June, turf quality and leaf water content in mid-August had declined about 12.1%-49.8% and 14.2%-27.6%, respectively. Similarly, the activities of SOD and POD in leaves declined 36.5%-55.0% and 46.9%-65.7%, respectively, while the MDA content increased from 19.8% to 88.7%.

The two volcanic materials are similar but are also different ①the partition mode of rare-earth element is similar to that of the basalt.②the increase content of the rare-earth element content in transitional layer shows that it enrichs in this segment due to the volcano events. Moreover, the comparability of the partition mode shows that the volcano-genic materials and the basalt are of the same source.③low Eu anomaly different from the high Eu anomaly of medium-acidic tuff in Meishan section, that show that their formation is different④there are plentiful basalt detritus.⑤there are enrichment of the Ti element.⑥the lower content of siderophile element of Ni and Co, especially in the transitional layer, show that there were not extraterrestrial events and big scale basic or ultrabasic volcano eruption events in this area. These characteristics show that the sedimentary source of Xuanwei Formation and Kayitou Formation is basalt.
1稀土元素配分模式与玄武岩类似;(2)稀土元素含量在异常层的增加反映了火山事件导致了它在该段地层中的富集,而配分模式的相似性反映了火山物质来源与玄武岩具有同源性;(3)低"Eu"异常区别于煤山剖面的中酸性凝灰岩高"Eu"异常模式,说明界线粘土岩成因也不同于煤山剖面的界线粘土;(4)大量的玄武岩岩屑;(5)Ti元素的富集;(6)亲铁元素Ni和Co含量较低,特别是在界线异常层含量降低,表明本区在界线处可能并不存在地外事件和大规模基性、超基性火山喷发事件,这些特征反映本区宣威组和卡以头组物质来源主要为玄武岩。

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。
