Aspergillus strain capable of promoting root growth of Casuarina

Abstract

The invention relates to an aspergillus strain capable of promoting root growth of Casuarina. The strain is Casuarina rhizosphere fungi 63 of Aspergillus sp., and is registered and preserved in China General Microbiological Culture Collection Center on June 28, 2012, with an accession No. being CGMCC No. 6311. The Casuarina rhizosphere fungi 63 is inoculated on hydroponic seedlings of the Casuarina, and a comprehensively evaluation is carried out according to various indicators of root growth, and promotion effects of the fungi on root growth is further confirmed, thereby finding a functional endophytic fungi which is benefit to promote root growth and can be applied in 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...
