Two species, Lunathy rium coreanum and Dryopteris crassirhizoma, were selected. The ef fects of vase-holding and fresh preservation of the cut leaves under different conditions was studied. By measuring the contents of soluble protein and chlorophyll of leaves, the best methods of fresh preservation was determined with the use of fresh preservation and wet storage. L. rium coreanum (christ) Ching may last 14 days. The best liquid used to arrange flowers in a vase is 5 g/L sucrose.With the use of fresh preservation liquid and wet storage. D. crassirhizoma may last 34 days.展开更多

Pteridophyte flora of the Himalayan region is considered to be the basic requirements for the knowledge of pteridology. This paper aims to provide the overview of fern and fern allies present in the Nubri valley and its adjoining areas of Manaslu Conservation Area (MCA), Central Nepal. A total of 105 species belonging to 45 genera were recorded, with Dryopteris as the largest genera including twelve species followed by Athyrium, Pteris and Polystichum. With regard to habitats, most of the species were terrestrials followed by lithophytes and epiphytes.展开更多
There are almost 400 species(containing 8 varieties)of pteridophytes on Hainan Island,belonging to 43 families and 114 genera,one third of which are officinal.To understand the distribution of pteridophytes resources ...There are almost 400 species(containing 8 varieties)of pteridophytes on Hainan Island,belonging to 43 families and 114 genera,one third of which are officinal.To understand the distribution of pteridophytes resources of Hainan Island,we conducted this survey mainly by photographing the habitat,plant morphology,sorus and specific traits of some pteridophytes.The results showed that nearly 32 families and 94 species were recorded.These pteridophyte herb resources play important roles in medical treatment of native Li nationality people.展开更多
