广西姬小蜂科分类学研究(膜翅目:小蜂总科)

根据1998－2000年作者在广西南部山区的采集,结合中国科学院动物研究所昆虫标本馆馆藏标本的研究,报道了该科4亚科27属81种在广西的分布,其中,4属60种是中国新纪录,本文对前人和作者最近对中国姬小蜂科的分类研究简单作了综述,并对广西的姬小蜂科物种进行了初步的组分分析,根据现有材料得出结论是：1）广西的姬小蜂科区系成分以东洋区和古北成分为主;2）多个区纱成分分布相互重叠,交错。     

广西苦苣苔科植物区系和生态特点研究

滇黔桂及其邻近地区是我国苦苣苔科植物的分布和特有中心 ,广西正处于这个中心的位置上 ,种类十分丰富 ,共计有 38属、 16 6种 (含种下等级 ,下同 ) ,属和种的分布区类型不太复杂 ,特有现象极为突出 ,其中仅产广西的特有属有 5个 ,特有种达 81个。广西苦苣苔科植物区系与相邻的贵州、云南两省属的相似性系数较高 ,分别为 75 76 %和 71 4 2 % ,但与相邻省份苦苣苔科植物种的相似性系数却较低 ,从 35 4 8%至 6 4 9%不等。苦苣苔科植物在广西全境分布较广泛 ,但各地种类分布很不均衡。广西苦苣苔科植物的天然分布对基质有较严格的专一性 ,种群植株数量一般较少 ,同一种类不同的居群间形态变异较大。

中国姜黄属植物的订正

将白顶姜黄（CurcumaalbicomaS．Q．Tong）归入川郁金（C．sichuanenslsX．X．Chen),将另一种“川郁金”（C．chuanyujinC．K．HsiehetH．Zhang）归入广西莪术（C．kwangsiensisS．G．LeeetC．F．Liang）。认为过去把莪术鉴定为C．zedoaria（Christ．）Rose．C．caesiaRoxb．或C．aeruginosaRoxb,其实都是C．phaeocaulisVal．的误定;C．elataRoxb．是C．wenyujinY．H．ChenetC．Ling的误定;认为广西莪术的两个变种,即紫脉莪术（C．kwangsiensisvar．affinisY．H．Chen）和毛莪术（C．kwangsiensisvar．puberulaY．H．Chen）不能成立．对台湾是否产C．viridifloraRoxb．表示怀疑。附有中国产姜黄属植物12种的检索表及其分布．

大戟科野桐属4种6个居群的核型研究

采用常规压片法对大戟科野桐属4种(含变种)6个居群进行了体细胞染色体数目和核型研究。研究结果显示其染色体数目为2n=22或2n=44,核型均为1A。核型公式分别为:绒毛野桐2n=4x=44m;白背叶2n=20m 2sm或2n=2x=22m或2n=20m(2sat) 2sm;广西白背叶2n=2x=22m;毛桐2n=2x=22m。其中白背叶[Mallotus apelta(Lour.)Muell.-Arg.]、广西白背叶[M.apelta(Lour.)Muell.-Arg.var.kwangsiensisMetic.]和毛桐[M.barbatus(Wall.)Muell.-Arg.]的染色体数目和核型均为首次报道。根据野桐属细胞分类学资料推测,多倍化和异基数变异是野桐属属内物种形成的重要方式。     

Germination,growth and survival of <Emphasis Type="Italic">Berberis thunbergii</Emphasis> DC. (Berberidaceae) and <Emphasis Type="Italic">Berberis thunbergii</Emphasis> var. <Emphasis Type="Italic">atropurpurea</Emphasis> in five natural environments

Germination, growth and survival of green Berberis thunbergii and its purple ornamental form, Berberis thunbergii var. atropurpurea, were compared in five natural environments (full sun meadow, edge of woods, moist woods, dry woods, pine woods) to determine whether these two forms have a similar ability to naturalize. Berberis thunbergii and Berberis thunbergii var. atropurpurea had similar germination rates of about 25% at the end of 3 years. Most of the seed germination occurred in year one (89%), with a small amount of additional germination in year two (10%), and even less in year three (1%). Greatest germination occurred in the moist woods and full sun meadow sites and the least occurred at the pine woods site. Germination was reduced in the pine woods environment by the thick leaf litter layer present there. Barberry seedling survival during the first year was only 22% and survival dropped to 11.3% by the end of 2 years. Purple barberry seedlings had a lower 2 year survival rate than green barberry. There was no difference in seedling growth between purple and green barberry seedlings, but surviving seedling growth rates at the five environments were comparable. Seedlings achieved maximum growth in the edge of woods environment, but also grew well in the full sun meadow environment. At harvest, the full sun meadow had the greatest number of seedlings present, while no seedlings survived in the pine woods site.     

Detecting the influence of ornamental Berberis thunbergii var. atropurpurea in invasive populations of Berberis thunbergii (Berberidaceae) using AFLP1

Japanese barberry (Berberis thunbergii DC.) is a widespread invasive plant that remains an important landscape shrub represented by ornamental, purple-leaved forms of the botanical variety atropurpurea. These forms differ greatly in appearance from feral plants, bringing into question whether they contribute to invasive populations or whether the invasions represent self-sustaining populations derived from the initial introduction of the species in the late 19th century. In this study we used amplified fragment length polymorphism (AFLP) markers to determine whether genetic contributions from B. t. var. atropurpurea are found within naturalized Japanese barberry populations in southern New England. Bayesian clustering of AFLP genotypes and principal coordinate analysis distinguished B. t. var. atropurpurea genotypes from 85 plants representing five invasive populations. While a single feral plant resembled B. t. var. atropurpurea phenotypically and fell within the same genetic cluster, all other naturalized plants sampled were genetically distinct from the purple-leaved genotypes. Seven plants from two different sites possessed morphology consistent with Berberis vulgaris (common barberry) or B. ×ottawensis (B. thunbergii × B. vulgaris). Genetic analysis placed these plants in two clusters separate from B. thunbergii. Although the Bayesian analysis indicated some introgression of B. t. var. atropurpurea and B. vulgaris, these genotypes have had limited influence on extant feral populations of B. thunbergii.

HPLC Analysis of Theanine and Gallic Acid inthe Species of Camellia sect. Thea

Bymeans of HPLC technique, the theanine and gallic acid in the leaves of six species and three varieties of Camellia sect. Thea were analyzed. The results showed that both of them were generally occured in these plants and the contents in C. taliensis and C. kwangsiensis are mostly close to those of C. sinensis var. assamica. Since the leaves of C. taliensis have also been historically used for preparing tea by folk peoples of Yunnan province, it could be suggest that C. taliensis might one of the original plants of tea     

春季—冻融交替时期9种落叶及半常绿小灌木抗寒性综合评价

在春季—冻融交替时期,以北京地区迎春、金叶女贞、小花溲疏等9种落叶及半常绿小灌木一年生枝条为试材,通过人工模拟降温,测定其在4~-20℃低温胁迫下的6个生理响应指标,并对各指标进行相关性分析。结果表明,相对电导率、半致死温度、游离-脯氨酸含量和相对含水量这4个生理指标可作为9种小灌木抗寒性的评价指标。利用主成分分析、隶属函数法进行抗寒性综合评价,发现9种小灌木的抗寒性强弱顺序为:小花溲疏紫叶小檗太平花红王子锦带迎春连翘金叶女贞棣棠金山绣线菊。通过聚类分析可将9种小灌木分为3类,小花溲疏和紫叶小檗归为一类,其抗寒性相对较好;太平花、红王子锦带、迎春和连翘聚成一组,抗寒性一般;金叶女贞、棣棠和金山绣线菊聚在一起,抗寒性相对较差。
