河南铁线莲属植物分类学研究(英文)

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。

Polypores on Spruce in Northeast China

Poroid species of wood-inhabiting fungi growing on spruce (Picea koraiensis Nakai or Picea yezoensis (Sieb. & Zucc.) Carriere) in Northeast China were investigated during 1993-2002, and 71 species were recorded from these trees or their wood. Skeletocutis lilacina A. David & Jean Keller and Skeletocutis papyracea A. David are new to China. Fomitopsis pinicola (Sw.:Fr.) P. Karst., Onnia leporina (Fr.) H. Jahn, Perenniporia subacida (Peck) Donk, Phaeolus sckweinitzii (Fr.:Fr.) Pat., Phellinidium sulphurascens (Pilat) Y.C. Dai and Phellinus yamanoi (Imazeki) Parmasto are the pathogens on the two trees. Among the 71 species 18 species (ca. 25% of all species) are considered as rare species, 34 species (48% of all species) are the occasional species, and 19 species (27% of all species) are the common species.

Nutritive value of introduced bamboo species in the northwestern Himalayas,India

Bamboos are used extensively for a variety of purposes, and many new species have been introduced to the northwestern Himalaya. However, their potential as a fodder species has not been investigated. Six bamboo species, namely Dendrocalamus hamiltonii Gamble, Dendrocalamus asper(Schult. and Schult.f.) Backer ex K.Heyne, Melocanna baccifera(Roxb.) Kurz, Phyllostachys aurea Riviére and C. Riviére, Phyllostachys bambusoides Sieb and Zucc. and Phyllostachys pubescens(Pradelle)Mazel ex J. Houz. were evaluated for their nutritional value, relative palatability and best lopping time. Dry matter(DM), ether extract(EE), and crude fibre varied from(37.0–67.7)%,(4.7–7.6), and(22.1–37.9)%, respectively. Values of crude protein ranged from(12.2–17.1)%,total ash(TA) from(11.8–21.5)%, acid insoluble ash(AIA)from(0.3–0.5)%, nitrogen free extract from(31.1–40.8)%,carbohydrates from(57.0–69.0)%, organic matter(OM) from(78.5–88.2)%, calcium from(1.7–2.3)%, phosphorus from(0.4–0.8)%, potassium from,(0.9–1.6)%, magnesium from(0.5–0.9)%, sodium from(603.7–1072.7) 9 10~(-6) and vitamin A from(21.1–30.5) 9 10~(-2) mg/g, respectively. D.hamiltonii had maximum values for DM, EE, TA and AIA.OM and vitamin A were highest in M. baccifera. CF and carbohydrates were maximized in P. aurea and CP in P.pubescens. All the values obtained for different bamboo species were less than maximum tolerable concentration of common feed resources of the region thereby indicating their suitability for nutrition and palatability. The contents of anti-nutritional factors, namely hydrocyanic acid and tannin ranged from(33.8–61.7) 9 10~(-2) mg/g and(0.7–1.9)%, respectively. P. pubescens was the best species from a palatability point of view and has maximum crude protein content(17.2%), Ca(2.3%) and lowest tannin content(0.7%). The relative palatability of introduced bamboo species followed trend: P. pubescens(97.6%) [ D. hamiltonii(92.5%) [ P. bambusoides(81.2%) [ D. asper(76.9%) [ M. baccifera(75.9%) [ P.aurea(73.4%). The optimum months for lopping these species for green leaves are November and December, as the nutritional value declines sharply thereafter.
