Bioecological features, morphological and anatomical characteristics of Crocus korolkovii were studied. Phenology was studied by I.N. Beideman, biology bloom by A.P. Ponomarev, breeding and seed production of plants by T.T. Rakhimova. The study of the biology of flowering determined the optimal humidity, air temperature and soil surface. The anatomic study used fresh tissue samples which were fixed in 70% alcohol. A cross-section of the sheet and the structure of the flower in the introduction of conditions were studied.展开更多

Fish maw is mainly produced from croaker, which is the most highly priced. However, some of the fish maw being sold as croaker maw are in fact not from croaker, but from the Nile perch Lates niloticus. The present work determined and compared the proximate composition, amino acid and fatty acid composition of croaker Protonibea diacanthus maw and perch L. niloticus maw. The results indicated that both maws were high protein sources and low in fat content. The dominant amino acids in both maws were glycine, proline, glutamic acid, alanine and arginine. These amino acids constituted 66.2% and 66.4% of the total amino acids in P. diacanthus and L. niloticus, respectively. The ratio of FAA: TAA(functional amino acids: total amino acids) in both maws were 0.69. This is a good explanation for why fish maws have been widely utilized as a traditional tonic and remedy in Asia. Except valine and histidine, all the essential amino acid contents in P. diacanthus were higher than in L. niloticus. Moreover, croaker P. diacanthus maw contained more AA and DHA than perch L. niloticus maw, showing a higher ratio of n-3 / n-6, which is more desirable.展开更多
目的建立一种高效、精准的DNA条形码技术准确快速鉴定鱼胶物种。方法以细胞色素C氧化酶I(cytochrome C oxidase subunit I,COI)基因为靶标,筛选并优化DNA条形码引物,通过聚合酶链式反应(polymerase chain reaction,PCR)扩增和Sanger测...目的建立一种高效、精准的DNA条形码技术准确快速鉴定鱼胶物种。方法以细胞色素C氧化酶I(cytochrome C oxidase subunit I,COI)基因为靶标,筛选并优化DNA条形码引物,通过聚合酶链式反应(polymerase chain reaction,PCR)扩增和Sanger测序评估其鉴定效果。对市售鱼胶样品进行特异性扩增,结合生命条形码数据系统(barcode of life data systems,BOLD)和美国国家生物技术信息中心(national center for biotechnology information,NCBI)数据库进行物种比对,并采用邻接法(neighbor-joining,NJ)和系统发育树分析验证鉴定结果。结果通过筛选8对COI基因微型DNA条形码引物,最终确定了一组扩增目标片段约190 bp的引物组合,其PCR测序成功率达100%,物种鉴定准确率达98.15%。基于该引物对16份鱼胶样品的鉴定结果显示,仅56.25%的样本与标注物种一致,其中不符样品主要是鳘鱼胶和白花胶,鉴定阈值设为95%。进一步通过NJ分析和系统发育树构建,证实鱼胶样品的系统发育关系与BOLD/NCBI数据库比对结果高度一致,验证了鉴定结果的可靠性。结论本研究成功筛选出适用于鱼胶微型DNA条形码鉴定的引物,为鱼胶产品的真伪鉴别和质量控制提供了高效、可靠的技术手段。展开更多
