A pteridophyte is a vascular plant (with xylem and phloem) that reproduces using spores. Because pteridophytes produce neither flowers nor seeds, they are also referred to as "cryptogams", meaning that their means of reproduction is hidden. The pteridophytes include the ferns, horsetails, and the lycophytes (clubmosses, spikemosses, and quillworts). These are not a monophyletic group because ferns and horsetails are more closely related to seed plants than to the lycophytes. Therefore, "Pteridophyta" is no longer a widely accepted taxon, although the term pteridophyte remains in common parlance, as do pteridology and pteridologist as a science and its practitioner, to indicate lycophytes and ferns as an informal grouping, such as the International Association of Pteridologists and the Pteridophyte Phylogeny Group.

Tissue culture method of huperizia serrata
InactiveCN101889551AReduce pollutionReduce browning ratePlant tissue cultureHorticulture methodsPteridophyteFungal endophyte
The invention discloses a method for tissue culture method of huperizia serrata. The method comprises the following steps of: selecting an explant; killing surface bacteria; performing inoculation and cultivation; killing endophyte; performing propagation cultivation; and performing rooting cultivation. The huperizia serrata is a precious medicinal pteridophyte which has a tough requirement on a habitat, grows slowly under a natural condition and has a long production period. In a conventional method, propagation coefficient and biomass are low and requirements on medicament production cannot be met. Due to the adoption of the method, the differentiation rate of a huperizia serrata test tube plantlet is up to 90 percent, monthly multiplication multiple is up to 2.1 to 3.5, rooting rate is up to 100 percent, a root system grows quickly, root number is up to 1.6 to 3.4 per plant, a regeneration seedling grows healthily and the root system is developed. The method has the advantages of effectively restraining the pollution and browning of a huperizia serrata explant, promoting the survival and growth of the explant and providing important technical support for the realization of manual mass planting of the huperizia serrata along with simpleness, convenience, practicability, high efficiency and low cost.
