Infecting method for authenticating pathogenicity of sugarcane leaf fungal disease strains

Номер: CN104313111A
Принадлежит:

The invention relates to the technical field of sugarcane disease inspection, and provides an infecting method for authenticating the pathogenicity of sugarcane leaf fungal disease strains. The method comprises the steps of preparation of strains, collection and pretreatment of leaves, preparation of infected leaves, infection, culture and pathogenicity evaluation of strains. The method is characterized in that the preparation step of the infected leaves comprises the substeps: shearing the leaves into long segments of 4-8cm, wrapping two ends of the leaves with tissues, putting the leaves into a sterilized culture dish, and dripping sterilized clean water onto the tissues at the two ends of the leaves; and the infection step comprises the substeps: pricking two sides of the midribs of the leaves in the culture dish by using a pricking device, clipping hyphae to the pricked positions of the leaves by using sterilized tweezers to serve as a test culture dish. The method has the following ...

Method for rapidly detecting Leifsonia xyli subsp. Xyli based on nested PCR (polymerase chain reaction)

Номер: CN0102230018A
Принадлежит:

The invention discloses a method for rapidly detecting Leifsonia xyli subsp. Xyli based on nested PCR (polymerase chain reaction). Whether Leifsonia xyli subsp. Xyli exits is rapidly and accurately determined by extracting DNA of a sample, designing primers and performing the nested PCR. The detection sensitivity of the method provided by the invention reaches 100 fg genomic DNA of the Leifsonia strain and is increased by 100 to 1000 times as compared with the conventional PCR by using the same primers. The method provided by the invention is suitable for the quarantine inspection of sugarcane introduced varieties, the production of virus-free (bacterium-free) seedlings, the general survey of sugarcane ratoon stunting disease in sugarcane planting areas and so on.

Method for rapidly identifying resistance of transgenic Bt sugarcane to borer

Номер: CN0101113977B
Принадлежит:

The invention relates to a rapid identification method of transgenic Bt sugarcane resistance to Stem Borers by artificial inoculating. The method includes planting sugarcane in buckets in greenhouse, choosing insect source, artificial inoculating and evaluation of resistance. The experimental insect source of the same batch transgenic Bt sugarcane strain is the newly hatched larvae of the same striped sugarcane borer, or equally divides the newly hatched larvae of 2-3 female moth born to each sugarcane to be analyzed. The result can be investigated after 5 days of artificial inoculating to the sugarcanes planted in buckets in greenhouse and the pest resistance of the sugarcane strain is evaluated comprehensively according to the larval survival rate and sugarcane damage level. The most notable characteristics of the invention are: 1. the consistency and unity of inoculating time are guaranteed to the utmost extent to ensure the accuracy of identification; 2. The periodicity of pest resistance ...

Detoxication and tissue culture rapid propagation method of chewing cane axillary buds

Номер: CN0101803574A
Принадлежит:

The invention relates to the technical field of the detoxication and the tissue culture of sugarcane and provides a detoxication and tissue culture rapid propagation method of chewing cane, characterized by comprising the following steps of: (1) selecting and sterilizing plants; (2) carrying out the induced culture of axillary buds; (3) carrying out differentiation culture; (4) carrying out propagation culture; (5) carrying out rooting culture; (6) transplanting; and (7) detecting viruses (germs). The detoxication and tissue culture rapid propagation method of chewing cane is characterized in that a differentiation culture medium formula in the step (3) comprises the following components: 0.001-0.01mg/L of MS and TDZ, 0.02-0.05 mg/L of IBA, 30-40 g/L of cane sugar, 100-150 mg/L of arginine and 100-150 mg/L of inositol. The invention uses chewing cane axillary buds as explants, is easy to perform vaccination operation, and reaches the high survival rate over 90 percent. By the adopted differentiation ...
