Embodiment Construction

[0020] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0021] The application principle of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] like figure 1 As shown, the method for aseptic germination and rapid propagation of Panax chinensis seeds provided in the embodiment of the present invention comprises the following steps:

[0023] S101: Collect the fruits of Ginger japonica, peel off the seeds, remove the shriveled grains, put them in a paper bag, and store them in a refrigerator at 4°C for later use; put the seeds into the gauze and tie the mouth tightly, the gauze should not be too tight and there sho...

Abstract

The invention discloses an alpinia zerumbet seed aseptic germination and fast propagation method. The alpinia zerumbet seed aseptic germination and fast propagation method comprises the following steps: performing aseptic seeding induced germination by use of the seed, and then adopting a fast seedling propagation method for bud expanding propagation and rooting afterwards; taking the alpinia zerumbet seed as a propagation explant, and adopting the culture medium suitable for different growth stages of the alpinia zerumbet so as to enable the seed to germinate, propagate and root, thereby realizing the scale production of the alpinia zerumbet seedling. The acquired seed germination rate is 93.8% by use of the aseptic germination, the 30-day propagation magnification of the cluster buds obtained through propagation cultivation achieves 4.89 times, the seedling rooting rate of the rooting cultivation is 100%, and the transplanting survival rate achieves 100%.

Description

technical field [0001] The invention belongs to the field of plant tissue culture, in particular to a method for aseptic germination and rapid propagation of Ginger japonica seeds. Background technique [0002] Alpinia zerumbet (Persoon) B.L.Burtt&R.M.Smith is a perennial herb of the genus Alpinia, the plant is up to 3 meters high, with drooping inflorescences, white flowers, yellow lips with beautiful purple stripes, large flowers And gorgeous, flowering from April to June, is an excellent garden wood. There is no research report on tissue culture and rapid propagation. Ginger japonica seeds have a low germination rate and a small ramet propagation coefficient, making it difficult to quickly propagate seedlings. Most of the ginger plants are propagated by sucking buds or rhizomes, and it is difficult to multiply seedlings in a short time. [0003] To sum up, the germination rate of G. japonica seeds in soil is low, and the ramet propagation coefficient is small, so it is...
