四川重楼属(延龄草科)一新变种——峨眉重楼

报道了四川峨眉山地区延龄草科Trilliaceae重楼属Paris一新变种——峨眉重楼Paris polyphylla Smith var. emeiensis H.X.Yin,H.Zhang ＆ D.Xue。该变种与宽瓣重楼P.polyphylla var.yunnanensis （Franch.）Hand.-Mazz.相似,区别在于叶柄较短,长2–5mm,叶片较窄,披针形,宽1.5–2.5cm,花梗短,长6–10（–13）mm,花瓣丝状,长2–3cm,药隔突出部分较短,长0.2–0.5mm。高效液相色谱法对新变种及多叶重楼P.polyphylla Smith各变种的甾体皂苷类成分的对比分析显示,宽瓣重楼以薯蓣皂苷为主,长药隔重楼P.polyphylla var.pseudothibetica H.Li以偏诺皂苷为主,而峨眉重楼、多叶重楼P.polyphylla var.polyphylla、华重楼P.polyphylla var.chinensis（Franch.）Hara、狭叶重楼P.polyphylla var.stenophylla Franch.、宽叶重楼P.polyphylla var.latifolia F.T.Wang ＆ C.Yu Chang、白花重楼P.polyphylla var.alba H.Li ＆ R.J.Mitchell所含皂苷均为微量,由此揭示了峨眉重楼同近缘种之间的关系。

延龄草科四属花粉形态的研究

对延龄草科重楼属Paris L.延龄草属Trillium L.Medeola L.属和Scoliopus Torr.属以及百合科百合属Ｌilium L.和萱草属Ｈemerocallis L.花粉进行了光镜和电镜的观察和比较。结果表明,在延龄草科中,重楼属,Medeola属和Scoliopus属花粉具有较多的相似性：具单一远极沟,极面观椭圆形,外壁为网状纹饰或皱波－网状纹饰。而延龄草属花粉与它们的差异则较大,为圆形,无萌发孔,外壁非网状纹饰,而是颗粒状,疣状,芽孢状,星状和微刺状等纹饰。百合属中的Lilium michauxii和萱草属中的金针菜Hemerocallis citrina花粉均为单一远极沟,外壁表面为网状纹饰。但其网脊特别粗,具不规则突起并形成棱角（H.citina)或由许多排列成念珠状的、形状不一的分子组成（Lilium michauxii),结构特别复杂。就其萌发孔类型和纹饰特征看,它们与延龄草科中的重楼属,Medeola属和Scoliopus属花粉具有较多的性。花粉外壁的层次结构在延龄草科各属之间（延龄草属除外）,甚至在延龄草科与百合科之间均没有多大的差异。

四种重楼属植物光合作用特征

Species of Paris (Trilliaceae) have often been used as medicinal plants. Because of excessive exploitation,in this regard the wild resource of Paris is almost exhausted. Some species of Paris were transplanted for use in photosynthesis research and for conservation purposes. In the present study, light and CO2 photosynthetic response curves were investigated in four Paris taxa: P.polyphylla var. yunnanensis and var. alba, P.mairei, and P.marmorata. Our results showed that P.marmorata had the highest maximum photosynthetic rate (Pmax; 8.6μmol·m-2·s-1), light saturation point (LSP; 827μmol·m-2·s-1), maximum electron transport rate (Jmax; 39.9mol·m-2·s-1), a relatively high maximum carboxylation rate (Vcmax; 28.9μmol·m-2·s-1) and carbon dioxide saturation point (Cisat; 726μmol·mol-1), but a lower light compensation point (LCP; 6.23μmol·m-2·s-1) and the lowest carbon dioxide compensation point (Г*; 20.7μmol·mol-1). This suggests that P.marmorata is well adapted to light and CO2; however it has a low ability to acclimate to environmental stress as indicated by low water use efficiency (WUE) in high light conditions. P.polyphylla var. yunnanensis had the highest light compensation point (LCP; 10.1μmol·m-2·s-1), carbon dioxide compensation point (Г*; 35.3μmol·mol-1), carbon dioxide saturation point (Cisat; 727μmol·mol-1), relatively high maximum photosynthetic rate (Pmax; 7.5μmol·m-2·s-1) and light saturation point (LSP; 728μmol·m-2·s-1), maximum light saturated electron transfer rate (Jmax; 37.7μmol·m-2·s-1), suggesting that it is suitable for conditions of higher light and CO2 concentration. This taxon can adapt to adverse conditions, as suggested by high WUE under increased CO2 concentration. In contrast, P.polyphylla var. alba exhibited a relatively lower apparent quantum yield (AQY; 0.037μmol·mol-1) and poorer growth performance than the other taxa. We suggest from our results that different light and water conditions are suitable for the growth of the different taxa. Photosynthesis assimilation efficiency and production can be increased by raising humidity for P.polyphylla var. yunnanensis and P.marmorata. To protect plants of P.polyphylla var. alba from strong sunshine, they should be shaded from March to mid June.
