Abstract

The invention discloses a dendrobium fimbriatum seed tissue culture and rapid propagation method. Dendrobium fimbriatum seeds are sown in inducing culture media and induced to sprout, then dendrobium fimbriatum budlets are sequentially transplanted into successive transfer culture media and rooting culture media to continue to be cultured, and dendrobium fimbriatum rooting tissue culture seedlings are obtained and can be transplanted to a greenhouse for seedling hardening. The tissue culture method is simple and convenient, steps are easy, operation is convenient, dendrobium fimbriatum rooting tissue culture seedling plants are robust and have high growing capacity, and the method is suitable for factory production.

Description

technical field [0001] The invention relates to a method for rapid propagation of plants, in particular to a method for rapid propagation of dendrobium fringe seed tissue culture. Background technique [0002] Dendrobium is the fresh or dried stem of Dendrobium nobile Lindl., Dendrobium candidum Wall.ex Lindl. or Dendrobium fimbriatum Hook.var.oculatum Hook. and its similar species. In my country's traditional medicine, Dendrobium is a commonly used precious medicinal material, which was first recorded in "Shen Nong's Herbal Classic" and listed as top grade. [0003] Dendrobium fimbriatum Hook.var.oculatum Hook. is a plant of Dendrobium fimbriatum Hook.var.oculatum Hook., with thick stems, erect or drooping, hard texture, cylindrical or sometimes slightly spindle-shaped above the base, two rows of leaves, leathery, long Round or oblong-lanceolate, racemes 5-15 cm long, 6-12 flowers sparsely, golden-yellow, thin, spreading, slightly fragrant, flowering period 4-6 months, pro...
