The Plant Print Macroscopic And Apparent Structural Study Of Pteridophyte In Changbai Mountain Of China

In the several decades of research and study, Professor Lu Jingmei led a team to complete the study of plant print. It is the first time to use the dark division scanning technique successfully. it gives us a new way to study the plant print. It solves the problem of the extremely decomposed stomach contents can not be mounted. The plant print three-dimensional(3D) optical microscopy scan-imaging technology provides exactly and conveniently investigation clues for criminal detection. It has obtained the unprecedented development.In the present study, the leaf epidermises of Pteridophyta plants in 1700-2100m of Changbai Mountain were observed with optical microscopy using the Plant Print technology. There are about 50 genera, 600 species , mainly in the tropics. There are about 27 genera, 150 species in China and they distribute all over the country. We observed and studied about 6 species of ferns from Changbai Mountain, They are, respectively, Lycopodium annotinum L.; Selaginella tamariscina (Beauv.)Spr.; Equisetum arvense L.; P.aquilinum(L.)Kuhn; Osmunda cinnamomea L.var.asiatica Fernald; Athyrium multidentatum (Doeee)Ching. The results indicated that the plant print of Lycopodium annotinum L.cell wall is type C; The plant print of Selaginella tamariscina (Beauv.)Spr. cell wall is type G; The plant print of Equisetum arvense L. cell wall is type E; The plant print of Osmunda cinnamomea L.var.asiatica Fernald.cell wall is type F; The plant print of P.aquilinum(L.)Kuhn .Cell wall is type F; The plant print of Athyrium multidentatu(Doeee)Ching. cell wall is type F . The results indicated that, Pteridophyte in Changbai Mountain could be effectively identified according to the types of Plant Print and appendages of the leaf epidermises.The results show that the plant print has practical and high value, which could be use as the standard comparisons. It is directly used for examination appraisal. The technology can be used more widely in the area of criminal detection. The study of Plant Print apparent Structural opens new realms of criminal detection. The technology is the first at home and abroad to fill the gaps in the field.
