Abstract

The invention relates to a method for rapidly propagating sugarcane tissue culture seedlings with spermine. The method comprises the following steps: using sugarcane immature leaf slices as explants, vaccinating the explants to an improved MS solid medium of MS+Spm.1.5 mg . L<-1>-3.0mg . L<-1>, regulating the pH to be 5.8-6.0, and performing continuous culture for 10 d-25 d to induce and obtain sugarcane callus tissue agglomerates; retransferring the agglomerates to the same fresh culture medium for subsequent culturing for 15 d, and then separating and cutting obtained callus tissues into small blocks to be revaccinated to the same fresh culture medium; performing subsequent culture for 20d -30d, transferring regeneration seedlings to the same fresh culture medium to be cultured for 20d so as to obtain test-tube seedlings of which the stem length is 5-6cm and the root seedlings are complete. According to the invention, only one culture medium is used from the starting of explant culture to the generation of the complete regenerated plantlets, so that the production process for the sugarcane tissue culture seedlings is obviously simplified, besides, the toxic action of 2,4-D induction callus tissues is removed, and the cost of the used spermine is low, so that the method is more favorable for popularization.

Description

technical field

[0001] The invention belongs to the technical field of tissue culture of plant biotechnology, in particular to a method for rapidly propagating sugarcane tissue culture seedlings with spermine. technical background

[0002] "Tissue culture seedlings", also known as "test-tube seedlings", "sterile seedlings" and "clone (Clone) seedlings", are based on the totipotency theory of cells, using explants, in sterile and suitable medium and light temperature Under the condition of rapid breeding, the complete regenerated plants with complete roots and seedlings can be obtained. In the same period of time, the propagation speed of tissue culture seedlings can be dozens or even hundreds of times higher than the natural reproduction speed of plants, and it is disease-free and non-toxic (Virus), and the group is neat, which is most suitable for large-scale industrialization of improved crop varieties. to plant. Tissue culture seedling production technology is one of th...
