Journal of Integrative Agriculture 2015年第10期14卷 1936-1948页

作者： ZHAO Jing-lan wang Hong-wei ZHANG Xiao-cun DU Xu-ye LI An-fei KONG ling-rang State Key Laboratory of Crop Biology College of Agronomy Shandong Agricultural University Taishan polytechnic

Seven important grain traits, including grain length（GL）, grain width（GW）, grain perimeter（GP）, grain area（GA）, grain length/width ratio（GLW）, roundness（GR）, and thousand-grain weight（TGW）, were analyzed using a set of 139 simple sequence repeat（SSR） markers in 130 hexaploid wheat varieties and 193 Aegilops tauschii accessions worldwide. In total, 1 612 alleles in Ae. tauschii and 1 360 alleles in hexaploid wheat（Triticum aestivum L.） were detected throughout the D genome. 197 marker-trait associations in Ae. tauschii were identified with 58 different SSR loci in 3 environments, and the average phenotypic variation value（R2） ranged from 0.68 to 15.12%. In contrast, 208 marker-trait associations were identified in wheat with 66 different SSR markers in 4 environments and the average phenotypic R2 ranged from 0.90 to 19.92%. Further analysis indicated that there are 6 common SSR loci present in both Ae. tauschii and hexaploid wheat, which are significantly associated with the 5 investigated grain traits（i.e., GA, GP, GR, GL, and TGW） and in total, 16 alleles derived from the 6 aforementioned SSR loci were shared by Ae. tauschii and hexaploid wheat. These preliminary data suggest the existence of common alleles may explain the evolutionary process and the selection between Ae. tauschii and hexaploid wheat. Furthermore, the genetic differentiation of grain shape and thousand-grain weight were observed in the evolutionary developmental process from Ae. tauschii to hexaploid wheat.

NO2作为有害污染物，会引发光化学烟雾、酸雨和土地富营养化等。为了减少NO2的排放，各个国家和地区制定了相关的法律和法规。开发高性能的NO2传感器对于监测和控制NO2处理过程至关重要。利用Fe掺杂SrCoO3为敏感电极（SE）,钇稳定氧化锆（YSZ）为电解质，制备阻抗谱型NO2传感器。结果表明，在550℃下，Fe掺杂SrCoxFe1-xO3-SE传感器对不同浓度的NO2气体具有良好的响应能力；掺入Fe元素，传感器的灵敏度显著提高；在高浓度NO2气氛下，相角（Θ）响应值增加明显，在低浓度NO2气氛下，响应值未明显降低。综合考虑响应值和响应速率等因素，SrCo0.85Fe0.15O3-SE传感器敏感性能最佳，最佳工作温度为550℃,最大响应值高达27.1°,是未掺杂Fe之前的1.96倍。此外，在受到CH4、CO2、H2、NH3和NO等气体的干扰下，SrCo0.85Fe0.15O3-SE传感器仍然能够保持良好的选择性。研究可对固体电解质型NO2传感器研究提供参考。

In the present work, a novel method to extract three kinds of spices, namely vanillin, ethyl vanillin and ethyl maltol from food products such as biscuit, chocolate and milk powder was developed. 1-Octyl-3- methylimidazolium chloride （[Omim]Cl） aqueous solution was selected as the extracting medium. A 0.5 g powder of food product was extracted by 5.0 mL of [Omim]Cl aqueous solution （0.3 mol/L, pH 6.0） under ultrasonication at 50 ℃, and then the extract was centrifuged for 10 min at 4000 rpm. The extract was filtered through a syringe filter and injected into ion chromatography system for analysis. The separation of the three spices was carried out on an anion exchange column. The detection wavelength was set at 280 nm. Compared with traditional extraction solvents, [Omim]Cl aqueous solution displayed particular advantages. The applicability of the proposed method to real sample was confirmed. Under the optimal conditions, good reproducibility of extraction performance was obtained, with the relative standard deviation （RSD） values ranging from 1.9% to 6.3%. The recoveries of spiked samples were between ？9.8% and 95.8%. The detection limits （LOD, SIN = 3） of vanillin, ethyl vanillin and ethyl maltol were in the range of 20-45 μg/kg. The use of ionic liquid aqueous solution as extraction solvent was operationally easy and environmental-friendly.
