Abstract

The invention discloses a method for disinfecting the surface of cinnamomum longepaniculatum and separating and culturing endophytic fungi of cinnamomum longepaniculatum, and belongs to the technicalfield of fungus separation and culture. The method comprises the following steps: selecting mature healthy cinnamomum longepaniculatum, respectively collecting roots, stems and leaves, and respectively and sequentially rinsing with water 3-5 times, soaking with 95% ethanol 1-2 minutes, oscillating and washing with 4-5wt% sodium hypochlorite 4-5 minutes, soaking with 95% ethanol for 1-2 minutes andrinsing with water 5-6 times for disinfection treatment; and cutting and discarding surrounding tissues of the disinfected material, and inoculating the rest middle tissues into a PDA culture mediumcontaining chloramphenicol or a PDA culture medium containing chloramphenicol and cinnamomum longepaniculatum leaf leaching liquor or a PDA culture medium containing chloramphenicol and carrot juice or an MEA culture medium containing chloramphenicol for culture. According to the method, the surface of cinnamomum longepaniculatum tissue is disinfected, and endophytic fungi are protected against damage while the disinfection effect is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of fungal isolation and cultivation, and in particular relates to a method for disinfecting the surface of camphor oil and isolating and cultivating endophytic fungi. Background technique [0002] Oil camphor (Cinnamomum longepaniculatum (Gamble) N.Chao) belongs to Lauraceae and Cinnamomum genus. It is a national second-level key protected plant, and it is also a unique economic crop rich in natural aromatic oil in my country. At present, the planting area of ​​Yibin camphor oil exceeds 500,000 mu, accounting for more than 75% of the total resources of oil camphor in the country. The unique geographical features and climate characteristics of this area guarantee and preserve the biological independence of the species. Therefore, there may be potential endophytic fungal species resources completely different from other regions and other species in Yibin camphor. [0003] The isolation of endophytic fungi fro...
