A method for establishing a plant regeneration system of a swallow flower cluster bud approach

Abstract

The invention provides a method for establishing a plant regeneration system of the bud-forming approach of Swallows japonica, comprising the following steps: (1) seed disinfection: the mature Swallows swan seeds are sterilized with alcohol and NaClO solution; Germinate in bacterial water, use the basal growth points of seedlings with 2-3 primary leaves after seed germination to remove the roots as explants; (3) cluster bud induction and proliferation culture: inoculate explants in cluster bud induction proliferation culture In the medium, replace the medium every 30d; (4) rooting culture of tissue culture seedlings: when the clustered buds grow to 5-10cm, they are divided and trimmed, and inoculated in the rooting medium; (5) hardening and transplanting: rooting After 3 days of hardening indoors, the plants were transplanted into flower pots equipped with a cultivation medium (garden soil: vermiculite = 3:1) after 20 days of hydroponic cultivation. The method realizes the tissue culture and rapid propagation of the Swallows flower, promotes resource development and utilization, and can effectively protect the Swallows flower germplasm resource.

Description

technical field [0001] The invention relates to the technical field of plant tissue culture, in particular to a method for establishing a plant regeneration system for the budding pathway of Swallow Flower. Background technique [0002] Swallow flower (Iris laevigata), also known as flat-leaf iris and light-leaf iris, is a perennial herb of the genus Iridaceae. It is mostly distributed in Heilongjiang, Jilin, Liaoning and Yunnan in China, as well as in Japan, Korea and Russia. It is suitable for growing in swampy land. , Wetlands on the banks of the river. Swallow flower has been introduced and applied in botanical gardens all over the world, and it is a famous ornamental flower. It has bright flower color, elegant flower posture, tall and straight leaves, high ornamental value, strong group function, long history of cultivation, excellent cold resistance, and can adapt to various habitats. It is an excellent material for decorative environments and has various forms of gar...

Problems solved by technology

[0005] At present, the traditional propagation technology of Swallows flower has the disadvantages of low seed germination rate, slow propagation, and low ramet reproduction coefficient; the known plant regeneration system of Swallows flower is obviously restricted by seasons, and there is no clear report on the rooting rate and rooting coefficient of adventitious buds in the regeneration system. The establishment method of the plant regeneration system of Swallow flower still needs to be perfected
