Dendrobium officinale seed preservation device and method

Abstract

The invention belongs to the technical field of seed preservation and relates to a Dendrobium officinale seed preservation device and method. The device comprises a storage box and seed collection bottles; the seed collection bottles mounted in the storage box are used for storing Dendrobium officinale seeds. The Dendrobium officinale seeds are collected in the seed collection bottles. After mouths of the seed collection bottles are covered with bottle caps, and the outer surface, connected with the bottle cap, of each mouth is provided with a breathable seal film; the seed collection bottles are mounted in holes of bottle racks. The method includes: sterilizing tools, sterilizing capsules, collecting seeds and preserving at low temperature. The Dendrobium officinale seed preservation device and method has the advantages that the device is reasonable in structural design, the method is scientific and reliable, preservation time is long, survival rate is high, the requirements of Dendrobium officinale for perennial tissue culture can be met, and the device and method is applicable to collection and storage of like seeds.

Description

technical field [0001] The invention belongs to the technical field of seed preservation, in particular to a preservation device and a preservation method for dendrobium officinale seeds. Background technique [0002] Dendrobium officinale Kimura et Migo is a perennial herb of the genus Dendrobium orchidaceae. It is one of the five species of Dendrobium plants included in the Pharmacopoeia of the People's Republic of China. It is known as the life-saving celestial grass because of its functions such as human immunity, and it ranks first among the nine great celestial grasses in China. [0003] The main active ingredients of Dendrobium officinale are Dendrobium polysaccharides and dendrobine. The water-soluble polysaccharide contained in Dendrobium officinale is a kind of immune enhancer, which has strong anti-tumor biological activity, can promote lymphocytes to produce lymphokines, enhance the body's humoral and cellular immune functions, and enhance the body's autoimmunit...

Problems solved by technology

[0009] Planting Dendrobium candidum seeds for reproduction of Dendrobium candidum has a low survival rate, and now most of them use tissue culture methods for the propagation of Dendrobium candidum, but the preservation of Dendrobium candidum seeds is the key to realizing mass tissue culture propagation of Dendrobium candidum

[0010] At present, the preservation of Dendrobium candidum seeds generally adopts low-temperature preservation. The capsules of Dendrobium candidum are picked, and the full and uncracked capsules are put into a bag filled with silica gel, and then the bag is stored in a refrigerator. In this way, the seeds of Dendrobium candidum The storage time can not be very long, about 3-5 months, because the capsule shell of Dendrobium candidum is easy to break and produce cracks, and the seeds of Dendrobium candidum are very small, so it is easy to fall from the crack. The conventional method of preservation cannot meet the requirements of Dendrobium candidum. Perennial tissue culture requirements
