Embodiment 1

[0021] A kind of tissue culture fast breeding seedling method of hybrid tree that the present invention proposes, comprises the following steps:

[0022] S1, explant selection: get the new spruce that the hybrid tree takes out in the same year, cut the branch into 2-3cm bud stem segments as explants, clean them with washing powder aqueous solution, rinse, and then carry out disinfection and sterilization treatment;

[0023] S2. Induction culture: inoculate the explants on the induction medium, and use LED lights to cultivate and induce adventitious buds; the composition of the induction medium is as follows: MS+0.7mg / L BA+0.1mg / L NAA+30.0 g / L sucrose+5.5g / L agar, adjust the pH to 5.8-6.0;

[0024] S3. Subculture: inoculate the induced adventitious buds on the proliferation medium, and use LED light to illuminate for subculture; the composition of the proliferation medium is as follows: WPM+1.0mg / L BA+0.5mg / LKT +30.0g / L sucrose+5.5g / L agar, adjust the pH to 5.8-6.0;

Abstract

The invention discloses a tissue culture rapid propagation seedling method of hybrid paper mulberry, and belongs to the technical field of hybrid paper mulberry plantation. The tissue culture rapid propagation seedling method of hybrid paper mulberry comprises following steps: explant selection, induced culturing, subculturing, rooting culture, and transplanting. According to the tissue culture rapid propagation seedling method, current year stems with buds are selected as explants, the meristematic capacity is excellent, and differentiation propagation is more convenient to realize; LED illumination culture is capable of adjusting culture material growth process, increasing the environmental adaptability, realizing reasonable optimization on composition of induction medium, proliferationmedium, and rooting medium, and illumination conditions of different stages, increasing seedling tissue culture efficiency, and achieving relatively induction rate, reproduction rate, and rooting rate; the adventitious bud induction differentiation rate is 94% or higher; after subculture, average seedling height reaches 3.5cm, rooting rate reaches 100%, and transplanting survival rate reaches 68%or higher. The tissue culture rapid propagation seedling method is adopted for seedling of hybrid paper mulberry, the seedling efficiency is high, the propagation coefficient is large, seedling cost is reduced, and the obtained tissue culture seedlings are strong, and are high in quality.

Description

technical field [0001] The invention relates to the technical field of hybrid tree planting, in particular to a method for asexually propagating seedlings of hybrid tree. Background technique [0002] The hybrid mulberry is a plant of the genus Moraceae. It is an aerospace hybrid mulberry that has been cultivated by comprehensive methods such as space-borne space breeding in my country in the past ten years. It has the characteristics of fast growth, high yield, high quality, and multi-resistance. The leaves of the mulberry tree contain crude protein and flavonoids. It is a high-quality plant protein feed. The comprehensive nutritional content exceeds that of bean plants. It can replace soybean meal and fish meal for the breeding of various animals. [0003] The seedling raising methods of hybrid mulberry tree include seedling cutting seedling raising and tissue culture rapid propagation seedling raising. However, the propagation coefficient of cutting seedlings is low, the...
