Abstract

The invention discloses a chrysanthemum one-step tissue culture quick breeding method. The method comprises the following steps of S1, obtaining aseptic tissue culture seedlings, collecting chrysanthemum explants, cutting the chrysanthemum explants into sections with buds and stems, sterilizing, cleaning, inoculating the sections to a culture medium to grow, transferring the sections to a new culture medium to grow after the new buds grow to be 2 to 3cm, and obtaining the aseptic robust maternal seedling with roots; and S2, one-step quick breeding, cutting the aseptic robust maternal seedlingobtained in S1 into sections with buds and stems, inoculating the sections to the culture medium to carry out passage and rooting culture, and enabling the sections with buds and stems to grow into complete plants. The method has the beneficial effects that the chrysanthemum tissue culture seedlings with roots do not need special seedling training, the robust growth is realized, the production cost is low, the genetic property of the obtained tissue culture seedling is uniform, the breeding coefficient is high, the breeding period is short, and the method is an effective path for the chrysanthemum tissue culture quick breeding; the culture medium of the tissue culture and the culture medium of the robust seedlings and roots belong to the same type of culture medium, so the operation difficulty is reduced, the culture efficiency is improved, and the application range is wide.

Description

technical field

[0001] The invention relates to the technical field of chrysanthemum cultivation methods, in particular to a one-step tissue culture and rapid propagation method for chrysanthemums. Background technique

[0002] Chrysanthemum, a perennial herb of Compositae, is one of the top ten famous flowers in China and has a long history of cultivation and breeding. Chrysanthemum is also a commonly used traditional Chinese medicine in China. It has the effects of dispelling wind, clearing away heat, improving eyesight and detoxifying. Mainly treat headache, dizziness, conjunctival congestion, dysphoria in the heart and chest, treatment of sores, swelling and poisoning. Modern pharmacological studies have shown that chrysanthemum has various pharmacological activities such as treating coronary heart disease, lowering blood pressure, preventing hyperlipidemia, antibacterial, antitoxin, anti-inflammatory, and anti-aging.
