Abstract
The invention provides a rapid propagation method of double-petal Jasminum sambac, which is used for large-scale production and propagation to meet the market needs. The tissue culture of double-petal Jasminum sambac comprises the following steps: A, disinfecting explants; B, obtaining sterile seedlings; C, growing and cultivating axillary buds; D, inducing cluster buds; E, rooting and cultivating; and F, exercising and transplanting seedlings. As the double-petal Jasminum sambac is propagated by the plant tissue culture method, the propagation is not influenced by external conditions and can be performed in all seasons while the occupied land of the seedlings is saved and the production cost is reduced; and moreover, all good characters of the parent can be maintained, and the hereditary character is stable. By using the method, a great number of good test tube seedlings can be formed in short time for large-scale and factory production, thereby providing abundant raw materials for the industries such as ornamental horticulture, spices, pharmacy and the like.
Description
Technical field
The present invention relates to bivalve jasmine method for quickly breeding, belong to artificial propagation and the cultivation method technical field of plant.
Background technology
Jasmine (Jasminum sambac L.) is perennial evergreen undershrub of Oleaceae (Oleaceae) gelsemium or the undershrub that slightly becomes the liana shape; Property happiness warm and moist; Originate in an India and an Arabic band; After introducing China,, adapted to China's south most of areas weather through long cultivation domestication.As a kind of important fragrant plant, Jasmine is the important source material of refining essential oil and basement system jasmine tea.At home, since the root of Jasmine or complete stool have treatment diarrhoea, alleviate medical value such as abdominal pain, anti-inflammatory and cultivated application as a kind of central bay herbal medicine.Also have the researcher to find that the jasmine tea fragrance of low concentration can effectively be releived because the pain that vegetative nerve is movable and mood is brought.Except medical value.Jasmine still is a kind of famous ornamental plants, is not only Philippine's national flower, also is chosen as Jiangsu Province in 2007 simultaneously and spends.Therefore, jasmine receives much concern owing to its important use is worth.
Because the ripening rate of jasmine is very low, in production application, all breeds through cuttage and seedling culture.But long-term cottage propagation is to cause weakening and viruliferous major reason of plant vigor, and has a strong impact on resistivity and fragrance of a flower quality and the quality of jasmine to adverse circumstance, and has restricted the breeding process of jasmine.
