Problems solved by technology

However, using the current common techniques for tissue culture of head cabbage and cultivating tissue culture seedlings on the existing head cabbage tissue culture medium for a long time will easily cause the tissue culture seedlings to gradually decline and lose their morphogenetic ability, showing weak plants, poor growth, and poor proliferation. rate drop
Even some tissue culture seedlings appear vitrification, and the petioles and leaves of the tender stems appear translucent and water-soaked, which makes the growth of test tube seedlings slow, and because the tender stems are not easy to induce rooting, the reproduction coefficient is greatly reduced. There is no wax on the surface of the stems and leaves of the seedlings, the level of polar compounds in the body is high, the water holding capacity of the cells is poor, and the transpiration of the plants is strong, so normal transplanting cannot be performed
For a long time, it is not conducive to the subculture, long-term preservation, rooting and transplanting of cabbage tissue culture seedlings

Abstract

The invention belongs to tissue culture, in particular to a common head cabbage tissue culture method. The method comprises the process steps of aseptic seedling culture, induction culture, multiplication culture, rooting culture, regeneration seedling transplanting and the like. The method provided by the invention solves the problems that in the prior art, the subculture, the long-time storage and the rooting transplanting and utilization of common head cabbage tissue culture seedlings cannot be favorably realized, and the like. When being adopted, the method has the advantages that callus tissue can grow on cotyledons on a common head cabbage induction culture medium, hypocotyls can be directly differentiated into adventitious buds, the tissue culture seedling multiplication times is 3.8 to 4.6, the growth condition of the tissue culture seedlings is strong, vitrification seedlings are few, the multiplication rate is high, and the rooting rate of the tissue culture seedlings can reach 100 percent, and the like.

Description

technical field [0001] The invention belongs to tissue culture, in particular to a method for tissue culture of head cabbage. Background technique [0002] Heading cabbage seeds are expensive and have a long seedling age. In order to improve land utilization, the method of raising seedlings first and then transplanting is often used in practice. Since the seedlings of head cabbage are taproots and have few fibrous roots, it is not conducive to the absorption of nutrients and water by the roots. After transplanting and planting, the growth is slow, they are not resistant to waterlogging and root diseases, and the yield is not high. In recent years, with the rapid development of agricultural mechanization, precision seeding, plug seedling cultivation, and transplanting machine colonization have been introduced into cabbage cultivation. How to eliminate the above-mentioned cultivation defects and increase the yield of cabbage has become an urgent technology to be solved. probl...
