Abstract

The invention provides a method for tissue culture and fast propagation of Chongyang wood, which uses Chongyang wood with axillary bud stem segments or Chongyang wood leaves as explants for tissue culture propagation. When the explants are Chongyang wood with axillary bud stem segments, the cultivation method is: sterilize the bud stem segments, then place the bud stem segments in the induction medium to directly obtain clump seedlings, and then cut the clump seedlings into individual seedlings and inoculate them one by one. Rooting culture is carried out on the rooting medium, and finally the seedlings after rooting and culture are refined and transplanted in sequence, so as to realize the rapid propagation of Chongyang tree. When the sterile leaves of Chongyang wood are used as explants, the culture method is as follows: sterilize Chongyang wood seeds, and cultivate the sterile leaves, then use the sterile leaves as the explants, and sequentially induce callus. , Callus differentiation, rooting culture process, the establishment of Chongyang wood tissue culture rapid propagation system. The invention has the advantages of simple operation, low cultivation cost, high reproduction efficiency, little influence by natural environment, and good market and industrial application prospect.

Description

technical field

[0001] The invention relates to the technical field of plant cultivation, in particular to a method for tissue culture and rapid propagation of Chongyang wood. Background technique

[0002] Bischofia polycarpa (scientific name: Bischofia polycarpa) is a deciduous tree of the genus Bischofia in the family Euphorbiaceae. It is a native tree species in my country and a famous garden ornamental tree species in China. Chongyang wood has the advantages of shade tolerance, loose soil requirements, water and humidity resistance, well-developed root system, and strong wind resistance. It is often distributed in the Qinling Mountains, south of the Huaihe River Basin, the middle and lower reaches of the Yangtze River, and some water network areas. Chongyang wood has a medium growth rate, luxuriant leaves, magnificent tree appearance, and red leaves in autumn. It is usually cultivated as a street tree and ornamental tree in gardens, and it is widely used in landscaping. ...
