五岭龙胆的形态组织学研究
Morphological and Histological Study of Gentiana davidii Franch
摘要
Abstract
Objective To establish an identification method for Gentiana davidii Franch.Methods Original plants and herbal properties were identified with pharmacognostical method,and its diagnostic characteristics were described.Different tissue parts and whole plant powder of G.davidii Franch.were studied by conventional optical microscopy,scanning electron microscopy combined with various microscopy methods.Results The morphological,trait and microstructure characteristics of G.davidii Franch.were obvious.The microscopic characteristics of the tissues were metazoan cortex visible in the transverse section of the roots,and the casparian strip was obvious in the transverse section of the stems.The epidermis of the leaves showed a cephalic bulge,and the cell wall of the epidermis cells showed a shallow wavy curve.There were stomata and non-glandular hairs in the lower epidermis of the leaves,and the cell walls of the epidermis cells were deeply wavy.The upper epidermis of the petal has a regular arrangement of cerebral striatum spherical protrusions,and the lower epidermis has a regular arrangement of ridge flat elongated protrusions.The pollen grains were oblong with three germination furrows and different sizes of surface decorative mesh.The seed was pear-shaped,the surface was honeycomb,I and II could be seen.Conclusion The microstructure of the features tissue of G.davidii Franch.can provide a basis for its authenticity identification,quality evaluation and formulation of quality standards,and at the same time offer e a new taxonomic basis for the taxonomy of gentian plants.关键词
