Composition of both spermatophyte and pteridophyte flora of a relict Alsophila spinulosa community in Wutongqiao Nature Reserve of Leshan region was discussed. It shows the proportion of Tropic and Cathaysia elements in both spermatophyte flora and pteridophyte flora was almost 2/3 of the total at the genus level, and even more at the family level. There was a distinct ancient endemism phenomenon in spermatophyte flora, owning to being 8 relict and remnant endemism genera in the total of 9. Furthermore, the proportion of Tropic and Cathaysia elements both at family and genus level in the pteridophyte flora were much greater.

GISH analysis showed Triticale have 2 items chromosomes presented yellow and others chromosomes presented chrysoidine, because yellow chromosomes combined the Thinopyrum intermedium DNA, others chromosomes dye by PI. 4. Analysis of resistance gene: CH-9916 is the hybrid progenies of Octoploid tritielytrigia TAI-7045 X common wheat "Jinmai33".

GISH分析结果表明,小偃麦衍生系CH-9916的42条染色体中有2条外源染色体因结合有探针DNA而呈现出较强的黄色杂交信号,而没有结合上探针DNA的普通小麦染色体经过PI染色呈现出桔红色,初步推断小偃麦衍生系CH-9916为一个"小麦一中间偃麦草"的代换系。

The evolutionary relationships were investgated by comparing the results from molecular data alone or molecular data combined morphological characters using different analysis methods: maximum parsimony by PAUP(superscript *) 4.0 and Bayesian inference by MrBayes 3.0B4. Base composition and ti/tv of 28S rDNA D2 regions were analyzed by PAUP(superscript *) 4.0. The results showed that GC content of the 28S rDNA D2 gene sequences of subfamily Euphorinae ranges from 40.00% to 49.25%. Transversion frequency of sequence variable sites among species of Euphorinae was higher than that of transition. The subfamily Euphorinae was proved to be a paraphyletic group with close relationship to subfamilies Neoneurinae and Cenocoelinae; only two tribes, Meterorini and Microctonini, were proved to be monophyletic groups; Centistini, Cosmophorini, Euphorini and Dinocampini were paraphyletic groups; the basal position of tribe Meterorini within Euphorinae was partially supported by our phylogenetic trees, and tribe Microctonini was proved to be a group at the top of the trees.

结果表明:优茧蜂亚科的28S rDNA D2基因序列片段的GC%含量在40.00%~49.25%之间变动,而对于碱基替代情况来讲,优茧蜂亚科各个成员间序列变异位点上颠换大于转换;不同的分析和算法所产生的系统发育树都表明目前根据形态定义出的优茧蜂亚科Euphorinae不是一个单系群,而是一个与蚁茧蜂亚科Neoneurinae和高腹茧蜂亚科Cenocoelinae混杂在一起的并系群;在优茧蜂亚科内部,悬茧蜂族Meterorini和食甲茧蜂族Microctonini(排除猎户茧蜂属Orionis)为单系群,而宽鞘茧蜂族Centistini、大颚茧蜂族Cosmophorini、优茧蜂族Euphorini、瓢虫茧蜂族Dinocampini为并系群;悬茧蜂族Meterorini在优茧蜂亚科Euphorinae内位于基部位置的观点得到部分的支持,同时食甲茧蜂族Microctonini被判定为相对进化的类群。

The results of the analysis to complete 18S rDNA and partial 28S rDNA D 6-7 domain sequences of 30 collembolan species supported the monophyly of Poduromorpha and Symphypleona, Entomobryoidea is not a monophyly, familia Neelidae should be separated from Symphypleona. The situation about the superfamilia of Tomoceroidea and the familia Neelidae need further studies. The results of the further analysis to complete 18S rDNA and nearlly completely 28S sequences of 4 Protura, 6Collembola, 5 Diplura, 5 Insecta, 10 Crustacean, using 1 Myriapoda and 1 Chelicerata as outgroups indicated that Protura, Collembola and Diplura are monophy, respectively, Protura and Diplura have the nearest realationship, they make sister groups with Collembola and all of them assemble with Insecta to make a monophy cluster of Hexapod; The results support the monophy of Pancrusracea, Crustacean is not a monophy cluster and the realationships between them with Hexapod need further reseachers.

对我国的14科27属30种跳虫的18S rDNA全序列和28S rDNA部分序列(D6-D7)的基因信息数据进行分析,结果支持原目、愈腹目的单系性,长角目不形成单系群,支持短角科从愈腹目中分出,但鳞总科和短角目的分类地位有待于深入分析探讨;进一步比对4种原尾虫、6种跳虫、5种双尾虫、5种昆虫和10种甲壳动物的18S rDNA全序列和28S rDNA全序列,以1种多足动物和1种螯肢动物为外群,进行系统关系分析,结果显示:原尾纲、弹尾纲、双尾纲分别为单系群,原尾纲和双尾纲优先聚为一支,然后和弹尾纲构成姐妹群,以上三类又和昆虫聚为一支,支持六足动物的单系性,支持泛甲壳动物,但甲壳动物并未形成单系,其各类群和六足动物之间的亲缘关系尚须进一步确定。3。

It was seen that the main microflora causing the spoilage of fresh mutton meat consisted of 3 gram-positive bacilli with spore (about 30% of the micro flora), 1 gram-positive coccus (about 2% of the whole microflora), 3 gram-negative spirilla (about 63% of the whole microflora), and 1 gram-negative bacillus (about 5% of the whole microflora). Potassium sorbate, EDTA and nisin were used as preservatives to inhibit the growth of the main strains representative for the spoilage of fresh lamb meat.

对屠宰后羊肉的微生物区系进行了调查,成功地分离出引起冷却羊肉腐败的主要革兰氏阳性菌和阴性菌8种,其中含芽孢的革兰氏阳性杆菌有3种,占整个微生物区系的30%;革兰氏阳性球菌1种,占整个区系的2%;革兰氏阴性螺旋杆菌3种,占整个区系的63%;革兰氏阴性杆菌1种,占整个区系的5%。

The second group are the mixtures of Jurassic coal-formed oils and Cretaceous-derived oils. The carbon isotope, n-alkanes and isoprenoids compositions of these oils are similar to core extracts from Jurassic coal measures. However, sterane and terpane compositions of these oils show affinity to Cretaceous source rocks. It is deduced that coal-formed oils dissolved the biomarker-rich Cretaceous bitumen of relatively low thermal maturity, and overprinting occurs during oil migration.

第二类原油具有侏罗系煤系烃源岩与白垩系湖相泥质烃源岩混源的特点,这类原油的碳同位素组成、正构烷烃分布特征和姥植比等均表现出煤成油的特征,但甾、萜烷烃类化合物组成与白垩系烃源岩接近,推测是由于侏罗系煤成油在向上运移成藏过程中,受到成熟度相对较低、生物标志物相对丰富的白垩系烃源岩的浸析作用所致。
