Embodiment

[0033] Embodiment: the application of I. ceruleus in promoting the growth of buckwheat

[0034] 1 Materials and methods

[0035] 1.1 Preparation of I. anteroides liquid spore suspension

[0036] Inoculate I. anteroides into an Erlenmeyer flask containing PDA liquid medium, place it on a 25°C, 150r / min constant temperature shaker for 7 days, and filter it with double-layer sterile filter paper to obtain a liquid spore suspension. Hemocytometer counted and diluted to 1.0 x 10 8 The spore / mL liquid spore suspension is ready for use.

Abstract

The invention discloses isaria cateniannulata and an application thereof. The microbiology classification of the isaria cateniannulata is named as isaria cateniannulata 19GAZ1-1, the Latin literaturename is Isaria cateniannulata 19GAZ1-1, the isaria cateniannulata is already preserved in China Center for Type Culture Collection (CCTCC) on December 13, 2019 in Wuhan University, Wuhan University, No.299, Wuhan District, Wuhan City, Hubei Province (opposite to the first appendix of Wuhan University), and the preservation number is CCTCC M 20191043. After an isaria cateniannulata liquid spore suspension is sprayed to buckwheat leaf surfaces, physiological indexes such as the plant height, the stem diameter, the leaf area, the root volume and the fresh weight of whole buckwheat seedlings are remarkably improved.

Description

technical field [0001] The invention relates to Isyriaceta annuli and its application, belonging to the technical field of microbes. Background technique [0002] Plant endophytes refer to a type of fungi that can survive in plant tissues without causing obvious disease symptoms to plant tissues. During the long-term evolution and natural evolution, plants and endophytes have formed a mutualistic symbiotic relationship. Entomopathogenic fungi (entomopathogenic fungi) are a class of fungi that can infect, morbidity, and death hosts such as insects and mites, and are often used as biocontrol agents for pest control. In recent years, more and more studies have shown that entomopathogenic fungi can colonize plants as endophytic fungi, which can promote plant growth, improve plant stress resistance, and resistance to diseases and insect pests. [0003] Isaria cateniannulata (Z.Q.Liang) Samson & Hywel-Jones, also known as Paecilomyces cateniannulatus Z.Q. Liang, is an important e...
