  • 2 the salt - resistant characteristic which is adapt to depressed level of photosynthesis , such as the formation of double palisade tissue , and soon
    适应光合水平降低的抗盐结构特征。如茎皮层同化组织的形成；叶片双侧栅栏组织或外周栅栏组织的形成等。
  • There are 2 - 3 layers of long - column - shaped palisade tissue under the upper epidermis , and there are a great number of mechanical tissues which made up of vascular bundle sheath
    上表皮下方有2 - 3层长柱形的栅栏组织，在主脉大侧脉外方具有由大量机械组织组成的束帽或束鞘。
  • The main results are shown as follows : 1 under nacl stress , the succulent degree of leaves was enhanced , which was showed by measurement of well - developed palisade tissues , water - storing parenchyma and thick epidermis layer made of big parenchyma cells
    另外随着nacl浓度增加，单位叶面积上的表皮细胞个数减少，表皮细胞长度、宽度、高度变大，即表皮细胞变肥厚，对叶的肉质化也有很大作用。
  • Drought resistances of leaves of 13 rasberry and blackberry were measured based on 7 xeromorphic indexes , including thickness of leaves , ratio of palisade tissue thickness to cutis tissue , thickness extent of palisade cell density , thickness of cuticular , thickness of two sides of cutis
    摘要选取7项叶片旱生结构指标（叶片厚度，栅栏组织厚度叶肉组织厚度，细胞密集度，角质层厚度，上、下表皮厚度） ，观察测定了13个树莓和黑莓品种的叶片的相关指标。
  • Thickness of upper and lower epidermis of leaves , width of xylem and phloem of annual and biennial branches , ratio of late wood to early wood , periderm thickness of biennial branches , and length of xylem ray present decreasing trends with latitude ascending ; while ratio of palisade tissue to spongy tissue , epidermis thickness of annual branches , and cortex thickness of biennial branches show unobvious variations with latitude increasing
    叶的上下表皮厚度、 1和2年生枝木质部及韧皮部宽度、晚材早材比值、 2年生枝的周皮厚度、木射线长等均随纬度升高而呈下降趋势；而叶的栅栏组织和海绵组织比值、 1年生枝表皮厚度、 2年生皮层厚度等解剖结构随纬度变化没有明显规律。
  • Based on the reseaching of lycoris leaf micro - morphology characters by sem scanning , light microscope viewing and using paraffin method in the article , we try to provide the proofs of experiment and the efffective characer indexes to discuss the system and evolution of the lycoris . we find these microscope characers through reseach are as follows : the arrangement type , density and the length of stoma ; the shape and length of the epidermal cells ; the ridge of epidermis ; the transverse shape of leaf ; the number of the vascular bundle ; the style of vessel arrangement of vascular bundle in the middle vein ; the layers of palisade tissue ; the ratio of the thicken of palisade tissue to that of spongy tissue ; the angle number of the middle leaf ; the type of ventilating cavity etc . these characters are different from those of species in lycoris , meanwhile these characters are similar to those of some species in lycoris . so these characters can be used as the character indexes for differentiating species and reseaching systematic evolution of lycoris ; we can divide lycoris into two subgenus by these characteristic indexes : the species of one subgenus are l . aurea ( l " her . ) herb , , chinensis traub , l . caldweuii traub , l . anhuiensis y . hsu et q . j . fan , l . longituba y . hsu et q . j . fan ; the species of another subgenu s are l . houdyshelii traub , l . albiflora koidz . ,
    研究结果表明：叶表皮的气孔排列方式、长度、长宽比，脊的明显与否，叶表皮上的颗粒纹饰的多少、大小，叶表皮细胞长度、长宽比、垂周壁形状，上部叶栅栏组织细胞层数、叶的维管束数、叶中脉导管组成数目，气腔类型，叶的脊部远轴面的角数，叶缘的形状等这些特征在种间存在差异，同时，在有些种之间又有相似性；因此，这些特征既可以作为区分种的证据，又是研究石蒜属植物系统演化的性状指标，根据这些性状指标，可以将石蒜属植物大致分为两个亚属：一是忽地笑、中国石蒜、短蕊石蒜、安徽石蒜、长筒石蒜，二是江苏石蒜、乳白石蒜、石蒜、玫瑰石蒜、稻草石蒜；在两个亚属中其中有些种如忽地笑、长筒石蒜、中国石蒜的亲缘关系则更近些。
  • The paper made an ecological anatomy , a cultivation experiment on the lime - soil habtat and an analysis on the diurnal variation of photosynthetic an transpiration rate from three aspects of morphology , transplantation , physiology . the conclusion is that : ( 1 ) from the viewpoint of morphological anatomy , it has typical xerophyte structure such as strong root system , small leaf area , dense floss under the leaf surface , high stomatal density , the small opening degree , developed vessels and palisade tissues etc
    从形态学、栽培学和生理学三方面对迷迭香进行生态解剖、石灰土上的栽培实验以及光合蒸腾速率日进程的分析，得出以下结论： ( 1 )在形态解剖上：迷迭香具有发达的根系，较小的叶面积，叶片下表面密被绒毛，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典型的旱生结构。
