F. pumila had the strongest capacity to adhere to walls, and it formed a quite good covering landscape by means of a large quantity of adventitious roots. Furthermore, it was tolerant to shade, and the effects of shading on its growth and landscape covering were very small. P. heterophylla had the rapidest growth and covering speed, and it adhered to walls by adhesive discs, but was defoliated in winter or after a long period of shading. The other three vines climbed walls using adventitious roots, and their adhering capacities were all relatively poor. However, E. fortunei still formed a relatively good covering due to its rapid growth and emerald leaf colour. After shading for four months, leaves of F, pumila, C. grandiflora, and P. serpens became thin, and accordingly their leaf weight per unit area significantly decreased. Shading also reduced chlorophyll contents of C. grandiflora and E. fortunei but enhanced those of F. pumila and P. serpens, It did not influence leaf thickness, leaf weight or chlorophyll content of P. heterophylla. Whether shaded or not, the relationship between Pn and PAR for each species could be expressed as y=alnx+b, and furthermore there was a significant (P.01) correlation between them. Pn and LCP values for all five lianas also significant (P.01) correlated. Shading reduced LCP values of P. heterophylla, C. grandiflora and E. fortunei but increased LSP of F. pumila.

结果表明，1薛荔对墙体附着力最强，它依靠大量的不定根吸固在墙体上，形成很好的覆盖效果，而且薜荔耐荫，遮光对其生长与覆盖的影响很小；爬墙虎的生长与覆盖速度最快，它主要依靠吸盘吸固墙壁，但在冬季或长时间遮光后出现明显落叶现象，影响其覆盖景观；其他3种都依靠不定根沿墙面攀援，附着力相对较差，但扶芳藤由于生长较快，叶色终年保持翠绿，也能形成相对较好的覆盖效果；2遮光4个月后，薛荔、凌霄和蔓九节的叶片变薄，相应地这3种植物单位面积的叶片重量都显著减轻；遮光还使凌霄和扶芳藤的叶绿素含量减少，使薛荔和蔓九节的增加，但对爬墙虎的叶片厚度、叶重和叶绿素含量都不产生明显影响；3无论遮光与否，5种植物的Pn与PAR之间的关系都可用y=alnx+b表示，并且都达极显著相关，Pn与光补偿点之间亦呈极显著相关；遮光还使爬墙虎、凌霄和扶芳藤的LCP下降，并使薛荔的光饱和点升高。

Yellow-throated marten\'s relationship is between Stone marten and Fisher marten.Fisher marten is the first species who was divided from Martes.The second one were Yellow-throated marten and Stone marten.Based on the analysis of the fossil note,Martes came from Central Europe,Fisher marten,Yellow-throated marten and Stone marten belonged to a branch which evolved to temperate zone.Boreal forest martens was another branch which evolved to cold environment.It is suggested that Yellow-throated marten and Fisher martenwere ascertained genus separately.4、By contrasting and analyzing 11 complete mitochondrial control region gene sequences of Mustelidae,the extended termination associated sequence domain、the central domain and the conserved sequence block domain were identified.A extended termination associated sequence(ETAS1) and eight conserved sequence(CSB-F、E、D、C、B、1、2、3) was indicated,and sequence mode was presented.Different kind of short repeat sequences were found between CSB1 and CSB2.With wolf as the outgroup,the phylogenetic evolution relationship of Mustelidae was analyzed using the neighbor-joining method.

而基于鼬亚科动物线粒体DNA12种重链编码蛋白基因序列及石貂和渔貂线粒体ND2和cyt b全序列，以狼、狗獾和水獭为外类群，应用NJ、MP和ML法构分别构建貂属和貂熊的系统进化树，结果表明：紫貂与日本貂亲缘关系较美洲貂近，石貂与真貂亚属亲缘关系较近，黄喉貂介于石貂和渔貂之间；渔貂是最早从貂属分化出的种类，其次是黄喉貂和石貂；结合化石记录分析，貂属起源于中欧地区，渔貂、黄喉貂和石貂属于一个向温带进化的分支，而真貂亚属为另外一个向寒冷环境进化的分支，建议将黄喉貂和渔貂分别定为单独的属。4、比对并分析11种鼬科动物线粒体DNA控制区序列，识别出延长终止序列区、中央区和保守序列区3个区域，指出了一个终止相关序列ETAS1及8个保守序列(CSB-F、E、D、C、B、1、2和3)，并给出了序列通式，在CSB1和CSB2之间发现具有不同形式的短串联重复序列。
