山东堇菜属（堇菜科）植物叶表皮微形态的比较研究

利用光学显微镜对山东堇菜属Viola L.20种2变种植物的叶上、下表皮微形态进行了研究。结果表明,该属植物叶表皮细胞为多边形或不规则形,垂周壁为波形、浅波形或平直弓形,气孔器为不等型（偶上表皮兼有平列型）。根据其上表皮是否具有平列型气孔器,可将其分为两个类型,即①上表皮有平列型气孔器,如三色堇;②上表皮无平列型气孔器,如该属绝大多数植物。类型②又根据叶表皮细胞形状和垂周壁式样之不同,进一步划分为4个亚类型。表皮细胞形状和垂周壁式样对该属内种、变种的鉴定具有重要的意义。不赞成将早开堇菜、茜堇菜合并到紫花地丁;不支持将阴地堇菜作为蒙古堇菜的鉴定;不支持将泰山堇菜合并到早开堇菜、将总裂叶堇菜降为裂叶堇菜的变种。     

A Study on the Genus Acidosasa of Bambusoideae

The genus Acidosasa was published by the present authors in 1979. It only had one species at that time, Acidosasa chinensis C. D. Chu et C. S. Chao. Since then species number of the genus steadily increases. The authors have rather comprehensively studied this genus and its related genera for F1. Reip. Pop. Sin. The present paper deals mainly with morphological characteristics of the genus Acidosasa and the differences from its related genera i. e. Arundinaria, Sasa and Indosasa. The genus Acidosasa is closely related to the genus Arundinaria in the type and origin of inflorescences and the vegetative appearance. But it differs from Arundinaria in the structure of florets. In Acidosasa, each floret is provided with six stamens, while in Arundinaria each floret is of only three stamens. The genus Acidosasa is similar to the genera Indosasa and Sasa in the numbers of stamens, but it is distinguished from lndosasa by its semelauctant (determinate) inflorescence, not iterautant (indeterminate) one, from Sasa by its taller stature and branch complement with three branches. We have carefully examined all the type specimens of Acidosasa and its related genera. A conclusion reached is that there are six species in the genus Acidosasa, most of which are native to S. China, with only one species in Viet Nam. Five specific binomials are reduced and one species is transferred into this genus. Two keys to species, respectively based on the flowering and vegetative characters, are given as follow: Key to species of the genus A cidosasa (1)(based on the flowering state) 1. Lemmas glabrous. 2. Spikelets stout, 3-6mm broad, pedicels 1.5-4cm long; lemmas large, 1.5-2.2cm long, with 15-19 nerves, subcoriaceous, not glaucous, shiny. 3.

河北平山发现锈胸蓝姬鹟

正2015年6月22日,在河北省平山县驼梁国家级自然保护区驼峰附近的华北落叶松林内(113°49′33″E,38°44′59″N,海拔2 056 m)观察到1雌1雄2只鹟科鸟类。雌鸟上体橄榄褐色,两翼各具1道棕白色的翼斑;喉部、胸部浅褐色,并略带皮黄;尾上覆羽沾棕色;眼周白色,嘴黑褐色。雄鸟上体暗蓝灰色,喉、上胸、两胁橙红色,腹部颜色逐渐变白,尾近黑色。发现时,雌鸟往返飞行于落叶松枝和地面进行觅食;雄鸟在落叶松上部的树枝上频繁地鸣唱。经查阅文献(约翰·马敬能等2000,曲利明2014,Clement et al.2016),确定该鸟种为锈胸蓝姬鹟(Ficedula hodgsonii)(图1)。

Competitive responses of the rare Viola elatior and the common Viola mirabilis

Viola mirabilis is abundant in Estonia; Viola elatior is rare. We tested whether these species differ in their competitive responses to a common grass. We used a pot experiment in which individuals of each violet species grew with 0, 2, 4, or 8 individuals of Festuca ovina in natural soil. The response patterns of shoot and root mass and leaf numbers of the two species were similar: the biomass and leaf number of both violet species decreased with increasing grass density. The decrease of root mass of the rare V. elatior was significantly greater, and the decrease of leaf number tended to be greater, than that of the common V.␣mirabilis. We conclude that the stronger competitive response of V. elatior compared to V. mirabilis might be one reason behind its lower regional and local abundance.

河北省侧蒴藓类植物区系的主成分分析

根据较系统全面地野外调查、标本鉴定和整理,采用植物区系谱的主成分分析方法,对河北省侧蒴藓类植物区系进行了研究。结果表明;河北省侧蒴藓类植物共计196种(包括种以下单位),隶属于17科,66属。其中,北温带地理分布类型占主导地位,共计98种,占总种数的50．79％;东亚地理分布类型54种,占总种数的27．77％;中国特有分布类型16种,占总种数的8．38％;东亚—北美分布类型9种,占总种数的4．71％;旧世界温带分布类型9种,占总种数的4．71％;热带分布类型(包括泛热带分布类型和热带亚洲分布类型)仅有3种,占总种数的1．57％。运用植物区系谱的主成分分析对河北省与我国相邻地区侧蒴藓类植物关系的研究表明：西藏和横断山为一组,相异系数分别为31．9和43．5,与河北的联系相差最远;河北—东北—秦岭—内蒙古—山东为一组,内蒙古和山东在地理位置上与河北接壤,但相异系数分别达21．0和15．6,而河北与东北、秦岭相异系数分别为6．4和12．0,它们在区系关系上更为接近。分析结果对吴鹏程(1998)关于中国苔藓植物分布路线的观点以有力的支持,即存在喜马拉雅南麓地区—秦岭—东北的苔藓植物迁移路线;同时,说明大的山脉是苔藓植物进行扩散和传播的重要通道。     

Characterization of newly developed microsatellite loci in the stemmed yellow violet,Viola pubescens (Violaceae)

Viola pubescens is a perennial herb with a mixed mating system involving the production of both open, chasmogamous flowers and closed, cleistogamous flowers. Using a nonradioactive protocol, 12 microsatellite primers that amplified loci with perfect and imperfect repeats were developed in the species. As examined in five populations of V. pubescens using multiplex reactions, all loci exhibited polymorphism with an average of 5.4 alleles. Most primers also amplified in 12 additional Viola species and one cultivar, revealing the possibility of wide applicability across the genus. This is the first known report of microsatellite loci developed in Viola and the Violaceae.

蔓茎堇菜总黄酮提取工艺初探

分别采用热水浸提法、甲醇浸提法和乙醇浸提法来提取蔓茎堇菜样品的总黄酮,并以芦丁为标准品,用紫外分光光度法在265nm处测定各提取液的总黄酮含量。结果表明,甲醇浸提法和乙醇浸提法显著优于热水浸提法,而用70％乙醇为提取溶剂时效果最佳。研究结果可为利用蔓茎堇菜工业化生产黄酮类药用成分提供科学依据。

A new species of Viola (Violaceae) from Turkey

A new species of Viola , V. kizildaghensis M. Dinç & S¸. Ẏlḋṙml̇, from Turkey is described and illustrated. It is found on the rocky slopes of K̇żldǎ, K̇żldǎ National Park, in the vilayet of Isparta, south-west Turkey, at an elevation of 1350–1600 m. It belongs to Viola , subsection Viola , and is similar to the Lebanese endemic V. libanotica Boiss., distinguished by its lanceolate, cuneate based leaves, pinkish-purple flowers with white throats, glabrous lateral petals, and peduncles bearing the mature fruit procumbent and pubescent. It is somewhat similar to another species from south-west Turkey, V. sandrasea Melchior, that is endemic to Sandras Dǎ in the vilayet Mǔla; it is distinguished from this by the characters listed above, its pubescent leaves and peduncles, and its linear-lanceolate to lanceolate stipules which have short, gland-tipped fimbriae. © 2002 The Linnean Society of London, Botanical Journal of the Linnean Society , 2002, 138 , 483–487.
