Abstract


Changbai honeysuckle (Lonicera ruprechtiana Rege1), the genus Lonicera Branch (Caprifoliaceae) honeysuckle (Lonicera Linn) deciduous shrub. Mainly located in the eastern part of China's three northeastern provinces, also distributed in the northern part of North Korea, the Soviet Union, eastern Siberia and the Far East. Changbai honeysuckle pharmacological effects has already done a preliminary study, and its variants pollen morphology observed. Anatomical Studies of the Changbai honeysuckle nutrition and reproductive organs by scanning electron microscope and paraffin sections were compared with the anatomical features Lonicera. Analysis and discussion of its taxonomic status of the relationship between the structure and the environment, and the introduction and domestication. The study results show that: 1. Distribution of cluster-like crystals in the the Changbai honeysuckle primary root cortex. Endodermis no Casparian strips. Star in the column, the beginning of primary xylem and phloem shape of isolated island, was radial radially arranged in the primary xylem, central to the formation of weak marrow. The primary root prototype, adventitious roots 3 prototype. 2. Changbai the honeysuckle newborn stem epidermal trichomes and glands exist. Endodermis no starch grains. True in the column, the primary xylem start pith central formation of the medullary canal. Cortex, tough parenchyma cells and myeloid rich druse. Changbai Lonicera year stems timber skin, strong features that reflect its growth potential. . Changbai honeysuckle root, stem secondary structure components similar are diffuse porous material. Pitted vessel with single pores, the pores, the pores group and radial diameter column complex arranged pores chain. Catheter with a single perforated plate, axial wood parenchyma, mostly near the tube, organization for the wing like Pong tube parenchyma and loop thin-walled; few ranks away from the tube, scattered polymerization parenchyma. Wood ray case profiled I allotype II multi-column wood rays column width of 2-3 cells, radial section upright cells nodular thickening evident. The secondary phloem unaccompanied cell differentiation. The periderm originated in the cortical parenchyma cells. The nog formation distribution layer into strips, and a long time does not fall off of dead tissue, so many deep cleft longitudinal groove bark. Phloem parenchyma cells and the shedding of the periderm contain druse. The average diameter of the root of the catheter than the stem conduit large stems catheter unit area than the roots, and long wood fibers more than roots. Stems catheter wall thread thickening than those roots, the rich tylosis. Root secondary phloem differentiation of bast fibers. 4. Changbai honeysuckle leaf bifacial leaf. Thick stratum corneum, the upper and lower epidermis covered with single-cell trichomes and multicellular glands, scanning electron microscope results showed that the tumor-like protrusions on the table fur. Epidermis than the upper epidermis density distribution of trichomes large and long, the veins near trichomes than blades Ministry. Stomatal are paracytic type the primary segment near the veins of the lower epidermis and upper epidermis and veins absence. Stomatal index of 0.214. The number of stomata per square millimeter is about 532. Palisade parenchyma and Hai Bo parenchyma ratio of 1.9:1. Mesophyll and veins, petiole parenchyma cells have large number of DRUSE distribution. The the petiole trace clover, trefoil gap.
