Abstract

The invention relates to a rapid breeding method for the tissue culture of bambusa texlitis. The method comprises the steps of obtaining sterile explants, inducing axillary buds, carrying out propagation on the axillary buds, and carrying out root induction. According to the method, a rapid breeding technology system for the tissue culture of the bambusa texlitis is built, so that the multiplication coefficient is increased, and the large-area popularization and planting can be conveniently realized in the production process.

Description

technical field [0001] The invention relates to a rapid propagation method for tissue culture of green bamboo, and belongs to the technical field of plant cultivation. Background technique [0002] green bamboo, Bambusa textilis McClure , also known as strip bamboo, mountain green bamboo, yellow bamboo, small green bamboo, grass family, distributed in southern China, including Guangdong, Guangxi, Taiwan, Hunan, Fujian, southern Yunnan, equivalent to the area south of 25 degrees north latitude, within its distribution range The annual average temperature is 18-20°C, and the annual rainfall is above 1400mm. It can grow well, and it can grow well in loose, moist, and fertile soil; it can grow on river banks, plains, hills, and all around (especially on both sides of rivers, basins, and plains. Grows best on alluvial soils). Suitable for growing in warm and humid climate environment. It is mainly produced in Guangdong, with the most in Guangning County, and it is also the lar...
