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。

The germinative number of horsebeans and peas were raised by 44% with activated water by tourmaline. 200μl 1 X 10~6/ml mouse's H_(22) cell, 200μ 4X 10~6/ml splenic cell, 200μl 1 × 10~6/ml epidermal cell were all inhibited after the action of tourmaline. It is analyzed that the factors which effected the multiplication of the cells included direct action which are tourmaline's electric field, far-infrared, negative ions and solvent ions, and indirect effect which are small water clusters and pH value.
电气石活化水使蚕豆和绿豌豆种子发芽速度均提高44%。0.5g电气石分别对200μl 1×10~6/ml的小白鼠H_(22)肝癌细胞,对200μl 4×10~6/ml小白鼠脾细胞,对200μl 1×10~6/ml的小白鼠表皮细胞的增殖起抑制作用,分析认为,电气石影响细胞增殖的因素包括电场、红外线、负离子和溶出离子对细胞的直接作用和通过改变水分子结构、培养基pH值的间接作用。

The dispersal unit is thus composed of sessile spikelet, rachis internode, and pedicel (the pedicelled spikelet falls separately), all of which contribute to the protection of the seed and are frequently ornamented or modified.In the more primitive members both spikelets of a pair are alike and fertile and are arranged in a terminal panicle. In most genera, however, the pedicelled spikelet has lost its fertility and differs in shape and texture from the sessile one.
驱散单位如此由无梗小穗,轴节间和花梗(pedicelled小穗分别下降)组成,其全部有助于种子的保护,在大多数属方面,不过,pedicelled小穗已经失去它的能育并且在外形上不同和来自无梗一的质地。

Oil pollutants not only impact wheat emergence, plant height, panicle length but also the germination rates of corn, soybean and cotton seed which is the impacted mostly. Through field comparative analysis between apple trees near wells and those without pollution, index of leaf senescence of fruit trees, apple leaf chlorophyll content and nutrient composition are impacted slightly by the development of oil.Specific measures for the environmental impact of oil development should be issued systematically from the perspective of the government and the public.
石油类污染物对小麦的出苗率、株高、穗长影响较大;石油类污染物对玉米、大豆和棉花种子的发芽率均有影响,其中影响最大的是棉花种子;通过野外调查选择油井附近的苹果树和对照点没有污染的苹果树进行对比分析,发现石油开发对果树的叶片衰老指数、叶片叶绿素含量和苹果的营养成分等影响较小。

The most significant variance lay in the 1000-seed-weight,followed by flag leaf length and inflorescence shape and then by distance between flag leaf and inflorescence with least in inflorescence length,plant form,leaf width and seed length.Meanwhile,morphological characteristics of D.glomerata have significant relationships: those with upright and constrictive inflorescences hav...
其中,种子千粒重变异最大;旗叶长度、花序形状次之;穗叶距、花药宽度、旗叶宽度等性状变异中等;而花序长度、株型、叶宽、种子长度变异最小。2鸭茅植物形态学特征间存在明显相关性,花序直立、紧缩的鸭茅,叶片窄长,茎秆粗壮,旗叶较长,雄性生殖器官发育良好,结种性能强;而花序下垂、开展的鸭茅则与之相反。3聚类分析表明,不同野生鸭茅种源可划分为3类,其中花序下垂种源聚于一类;而花序直立的种源分居另两类。4从形态学特征及相关农艺性状分析,花序直立的鸭茅更具开发利用潜力。

Four typical grassland communities, Stipa klemenzii, Stipa grandis, Leymus chinensis and Leymus chinensis + forbs, had been chosen along precipitation gradients from 200, 290, 350 to 450 mm respectively in Inner Mongolia Steppe. The objectives of this study were to determine the effects of grazing on plant community composition, aboveground and belowground biomass, species and functional group diversities and the relationship between diversity and productivity, the effects of grazing on soil seed bank species composition, seed density and diversity along the transect.
