Aspergillus strain capable of promoting root growth of Casuarina

Abstract

The present invention relates to an Aspergillus strain capable of promoting the growth of casuarina root system, which is Aspergillus sp. Casuarina rhizosphere fungus 63, which has been registered and preserved in the General Microorganism Center of China Microbiological Culture Collection Management Committee on June 28, 2012. The deposit number is CGMCCNo.6311. Casuarina rhizosphere fungus 63 was inoculated into casuarina hydroponic seedlings, and according to the comprehensive evaluation of various indicators of root growth, it was further confirmed that it can promote root growth. Finding functional endophytic fungi that are beneficial to root growth can be applied to Production.

Description

technical field [0001] The invention relates to an aspergillus strain capable of promoting the growth of casuarina roots. Background technique [0002] The study of plant endophytes began at the end of the 19th century when Vogl isolated the first endophytes from the seeds of ryegrass Lolium temulentum L. [1] . However, a large number of studies on endophytes in plants began in the 1980s, mainly in vegetation in temperate, subtropical and tropical regions. [0003] The predecessors can isolate endophytes from most plants, so it can be speculated that endophytes are ubiquitous in plants. Endophytes have been found in at least 80 genera and 290 species of grass crops worldwide [2] . According to their unique functions, the endophytes isolated from plants can be divided into: nitrogen-fixing bacteria, potassium-fixing bacteria, phosphorus-fixing bacteria and other plant growth-promoting bacteria [3~4] , Biocontrol bacteria with resistance to pests and diseases [5~8] And r...
