The diagnostic methods of extracelluar oxidase mat were used to select lignin-degrading enzymes producers among nineteen Ganoderma lucidum fungal strains. The results showed that the producing laccase activity of G.sp.var. Tianzhi was the highest,followed by that of G.lucidum 10 and G.lucidum 8.The producing lignin peroxidase activity of G.sp.var Tianzhi was the highes, and the producing Manganese peroxidase activity of G.sp.var yuanzhi 6 and G.lucidum G8 were the highest, followed by that of the G.sp.var. Tianzhi and G.lucidum 10. It was found that G.sp.var Tianzhi, G.sp.var. Yuanzhi 6, G.lucidum 8 and G.lucidum 10 showed the highest lignin-degrading enzymes activity. 相似文献

河南铁线莲属植物分类学研究(英文) 总被引：1，自引：0，他引：1
铁线莲属(Clematis L.)是一个在分类上较困难的类群,种类多,形态变化大。全球铁线莲属植物有350余种,中国有150余种。2006年7~8月我们对河南四大山区的铁线莲属植物种类进行了调查、采集和鉴定,标本存放于河南农业大学标本馆(HEAC),此外我们还认真观察了中国科学院植物研究所标本馆(PE)等国内各大标本馆的铁线莲属植物标本。结果表明河南铁线莲属植物24种和11变种,按照王文采等的铁线莲属新分类系统分别隶属于4亚属、7组、11亚组、15系,其中首次报道了半钟铁线莲(C.sibiricavar.ochotensis)和长冬草(C.hexapetalavar.tchefouensis)为河南铁线莲属植物新记录,首次报道了Clematis honanensisS.Y.WangC.L.Chang’作为Clematis pseudootophoraM.Y.Fang in W.T.Wang的新异名。增补《河南植物志》(1981)中未记录的有5种5变种:女萎(C.apiifoliaDC.)、毛萼铁线莲(C.hancockianaMaxim.)、大花威灵仙(C.courtoisiiHand.-Mazz.)、芹叶铁线莲(C.aethusifoliaTurcz.)、巴山铁线莲(Clematis pashanensis(M.C.Chang)W.T.Wang)、扬子铁线莲(C.puberulaHook.f.et Thoms.var.ganpiniana(Levl.et Vant.)W.T.Wang)、狭裂太行铁线莲(C.kirilowiiMaxim.var.chanetii(Levl.)Hand.-Mazz.)、大花绣球藤(C.montanaBuch.-Ham.ex DC.var.grandifloraHook.)、毛叶威灵仙(C.chinensisOsbeck.var.vestita(Rhed.Wils.)W.T.Wang)、狭卷萼铁线莲(Clematis tubulosaTurcz.var.ichangensis(Rehd.Wils.)W.T.Wang)。订正了《河南植物志》(1981)中6个分类群的学名:将C.uncinataChamp.var.biternataW.T.Wang作为C.uncinataChamp.的异名,C.brevicaudataDC.var.filipesRhed.作为C.puberulaHook.f.et Thoms var.tenuisepala(Maxim.)W.T.Wang的异名,C.brevicaudataDC.var.tenuisepalaMaxim.作为C.puberulaHook.f.et Thoms.var.tenuisepala(Maxim.)W.T.Wang的异名,C.argentilucida(Levl.et Vant.)W.T.Wang作为C.grandidentata(Rehd.et Wils.)W.T.Wang的异名,C.obtusidentata(Rhed.et Wils.)H.Eichler作为C.apiifoliaDC.var.argentilucida(Levl.et Vant.)W.T.Wang的异名;将Clematis ternifloraDC.var.latisepalaM.C.Chang作为Clematis pashanensisvar.latisepala(M.C.Chang)W.T.Wang.的异名。 相似文献

We investigated the influence of season on the rooting behaviour of eight important bamboo species viz., Bambusa balcooa, B.bambos, B. nutans, B. tulda, B. vulgaris, Dendrocalamus giganteus, D.hamiltonii and D. strictus. We collected 2 3 node culm cuttings in three growing seasons viz. spring (March), summer (June) and rainy (August)from superior candidate plus clumps (CPCs) centralized in the germ-plasm garden. Cuttings were placed horizontally in sand and were provided with intermittent misting at regular intervals. Bamboo species exhibited differential rhizogenesis behavior in different seasons. The study reveals significant variation in sprouting and rooting behaviour indifferent bamboo species. B. bambos had maximum rooting (78.89%),followed by B. vulgaris (74.44%). In general, the potential of different bamboo species for rooting was found to be in the order: B. bambos > B.vulgaris > B. balcooa > D. hamiltonii > B. tulda > D. strictus > D.giganteus >B. nutans. The maximum rooting was recorded in spring(56.67%), which was closely followed by summer (54.58%). In winter season, minimum rooting (36.67%) was observed. The interaction effect of species × season was also significant on sprouting and rooting parameters. In B. balcooa, B. nutans, B. vulgaris, D. hamiltonii and D.strictus, cuttings collected in summer season showed maximum sprouting and rooting, whereas, B. bambos, B. tulda and D. giganteus had maximum rooting in spring. The maximum number of roots developed per cutting was observed in B. tulda (43.8) during spring season. 相似文献

基于文献考证、标本查阅和野外调查,对景烈杜鹃Rhododendron tsoi(杜鹃花科)及其近缘类群主要形态性状的分类学意义进行分析,进而作分类学修订.结果表明:叶片的大小、形状、叶片先端的形态和叶背的毛被特征可以区分景烈杜鹃及其近缘类群,可作为划分种下等级的依据,而雄蕊长度及其与花柱的长度比较在种内变异很大,不能作为种及种下等级划分的依据.从而将景烈杜鹃及其近缘类群划分为1个种及4个变种,提出4个新组合变种名,即:背绒杜鹃R.tsoi vsr.hypoblematosum(Tam)X.F.Jin & B.Y.Ding、细石榴花R.tsoi var.nudistylum (Tam)X.F.Jin & B.Y.Ding、惠阳杜鹃R.tsoi var.huiyangense(Fang & M.Y.He)X.F.Jin & B.Y.Ding和千针叶杜鹃R.tsoi var.polyraphidoideum(Tam)X.F.Jin & B.Y.Ding.将棒柱杜鹃R.crassimedium和粗柱杜鹃R.crassistylm作为R.tsoi var.hypoblematosum的异名,将垂钩杜鹃R.unciferum和鼎湖杜鹃R.tingwuense归并入R.tsoi var.nudisttylum.描绘各个分类群的地理分布. 相似文献

Seeds of Acacia species and subspecies were characterized using an image analyzer and discriminatedfor the purpose of identification of species, using their seeds, The species considered in the study were Acacia nilotics subsp, indica, A. nilotica subsp, cupressiformis, A. nilotica subsp, tomentosa, A. tortilis subsp, raddiana, A. tortilis subsp. spirocarpa, A. raddiana, A. senegal, A. auriculiformis, A. farnesiana, A. leucophloea, A. mearnsfi, A. melanoxylon, A. planifrons and A. mangium. Eight samples each consisting of 25 seeds per species were studied using the image analyzer for physical characteristics of seeds, such as 2D surface area, length, width, perimeter, roundness, aspect ratic and fullness ratio. Discriminant analysis showed that acacias can be discriminated at species and subspecies levels, with 96% accuracy. Exceptions were A. nflotica subsp, tomentosa （75.0%）, A. tortilis subsp, spirocarpa （75.0%） and A. raddiana （87.5%） which had relatively low discrimination accuracy. However, discriminant analysis within selected species showed complete recognition of these species except for A. tortilis subsp, spirocarpa, that had still a large overlap with A. leucophloea. The study also revealed that both seed size and shape characteristics were responsible for species discrimination. It can be concluded that rapid analysis of seed size and shape characteristics using image analysis techniques can be used as primary and secondary keys for identification of acacias. 相似文献
