This paper made a systematic research on Lonicerafulvotomentosa Hsu et S.C. Cheng, which grows well inkarst areas, from its biological characteristics, such asmorphology, growth and physiology. The main conclusions asfollows:(1)From the viewpoint of morphological anatomy, it hastypical xerophyte structures such as well-developed epidermisand tissues that transport water effectively, small leaf area,dense floss under the leaf surface, high stoma density, thesmall opening degree, thick cuticle, well-developed xylem andpalisade tissues, etc. The pollen of L. fulvotomentosa isseems to be spherical, and has 3 grooves, much bulge on theepidermis evenly. The shape of pollen is an important featureon taxonomy. The ripe fruit has from 1 to 18 seeds, some fruitbranch has 135 berry, its diameter is up to 0.8 centimeter.(2)From the viewpoint of growth, L.

本文从形态解剖、生长发育的节律、光合生理特性以及种子萌发生理等生物学特性方面对喀斯特适生经济植物黄褐毛忍冬进行了较为系统的研究，得出以下结论：(1)在形态解剖上，黄褐毛忍冬根茎中含有发育良好的周皮和输导组织，导管密度大，横截面宽，周皮的形成具有节制蒸腾、通气作用和保护组织免受外界环境影响的作用，宽的导管对水分的输导效率高；叶片密被绒毛，面积较小，气孔密度大、开度小，厚的角质层和发育良好的木质部和栅栏组织等是典型的旱生结构；黄褐毛忍冬花粉近球形，具3 孔沟，表面具均匀分布的小刺，刺间具网状纹理。

Preliminary Identification of A Single Dominant Gene Conferring Resistance to Leafminer in Lycopersicon hirsutum Dunal;2. Biological characteristics of adult Opius caricivorae Fischer, a parasitoid of Liriomyza sativae Blandchard ;3. Opius caricivorae Fischer (Hymenoptera: Braconidae) is an important endoparasitoid of the vegetable leafminer, Liriomyza sativae Blandchard (Diptera: Agromyzidae) in China.

本文以检疫性害虫—美洲斑潜蝇 Liriomyza sativae Blandchard及其优势种天敌—黄腹潜蝇茧蜂opius caricivorae Fischer这一寄生体系为研究对象，对黄腹潜蝇茧蜂的毒液器官形态和超微结构、类病毒颗粒存在与否及其分布、毒液的蛋白组分及其对寄主的生理影响等进行了初步的研究，取得以下结果：(1)位于雌蜂腹部近背面的黄腹潜蝇茧蜂的毒液器官属于类型Ⅰ，由一个土黄色、锥状的毒囊、7个透明的椭圆形的毒腺和一个导管构成的，其中毒囊由发达的纵肌环绕。

Four different catechin content cultivars were selected from our tea germplasm appraisal database to assay the gene expression level of the seven genes, flavonol synthase, dihydroflavonol-4-reductase, leucoanthocyanidin reductase, anthocyanidin synthase, etc, which were involved in the flavonoids biosynthesis. The result showed that, the DFR and LAR transcripts were expressed increased with the increasing of tea catechin contents. Nevertheless, the others did not show this tendency clearly.

利用半定量PCR技术检测总儿茶素含量不同的4个茶树品种中与类黄酮合成相关的黄酮醇合成酶、二氢黄酮醇－4-还原酶、无色花色素还原酶、花色素合成酶等7个基因的表达情况，结果表明DFR和LAR基因的表达量与茶树中总儿茶素含量呈一定的相关性，而其他基因则与其相关性不大。

Armillaria luteo-virens is a ectomycorrhizal fungus symbiotic with some species of Kobresia in Tibet Plateau, China. A strain was recently isolated from fruitbody tissue of the fungus. To determine whether the strain is the pure culture of the fungus, the internal transcribed spacer region and the first intergenic spacer region (IGS-1) of the nuclear ribosomal DNA of fruiting body and the isolated strain were sequenced and compared. Further, the 5.8S/ITS and IGS-1 sequences of the species were BLAST matched with GenBank database on homology and a phylogenetic tree was constructed based on 5.8S/ITS sequence and two phylogenetic trees were constructed separately based on two IGS-1 sequences.

首次从采自青藏高原、与高原牧草嵩草属Kobresia草本植物形成外生菌根的黄绿蜜环菌Armillaria luteo-virens子实体中分离获得一组织分离菌株，运用rDNA-ITS和rDNA-IGS-1测序技术对该组织分离菌株是否为黄绿蜜环菌的纯培养菌种进行分子鉴定，并基于黄绿蜜环菌的5.8S/ITS和IGS-1序列进行核酸序列数据库GenBank同源性检索比对、构建系统发育树。

Results In the eleven kinds of Polygonum capitatum, those produced in Panxian, Kunming and Motuo contained the total flavone more, and the cultivated Polygonum capitatum in Shibing contained the total flavone more.

方法紫外分光光度法测定了头花蓼中总黄酮的含量。结果11批头花蓼中，贵州盘县、云南昆明、西藏墨脱等地野生头花蓼中总黄酮的含量较高，贵州施秉栽培头花蓼中总黄酮的含量较高。

The results of HPLC tests indicated that Bt toxin in Bt transgenic cotton had not obviously affected the contents of flavonoids (mainly rutin and isoquercitrin and a few quercetin ),contradictively ,the result of combined dosage test in vitro showed that that rutin had significantly enhanced the suppression of Bt-ICP on the cotton bollworm larvae., in addition to the

采用高效液相色谱法测定转Bt基因棉花主要抗虫黄酮类化合物的的变化，结果表明外源Bt杀虫蛋白表达不会对棉花自身原有的主要抗虫黄酮类物质（包括芸香苷、异槲皮苷和含量较少的槲皮素）产生不利的影响，因此可以将Bt杀虫蛋白基因转入抗虫黄酮类物质中国农业科学院博士学位论文含量高的棉花品系。
