| 1. | 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。 |
