An endophytic fungus of Chinese fir that can alleviate phosphorus stress

Abstract

The invention relates to a Chinese fir endophytic fungus capable of alleviating phosphorus stress. Described endophytic fungus is silk mold mold ( Papulospora? sp. ) AJ14, which was registered and preserved in the General Microorganism Center of China Microbiological Culture Collection Management Committee on May 20, 2014, with the preservation number CGMCC? No.9187. By applying the bacterium liquid of the strain, dipping the roots of Chinese fir seedlings in the early stage of planting and watering the roots of the Chinese fir woodland. The bacterial strains involved in the present invention are tested through the phosphorus stress test of the plants after inoculation, and the seedling height, biomass and chlorophyll content of the bacterial strains are all higher than the control to a large extent, indicating that it has a greater effect on alleviating the phosphorus stress of plants, thereby further confirming The obtained endophytic fungus can promote the growth and development of Chinese fir under the condition of phosphorus stress.

Description

technical field [0001] The invention relates to a Chinese fir endophytic fungus capable of alleviating phosphorus stress. 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 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 [5-7] And resistant ...

AI Technical Summary

Problems solved by technology

In summary, the research on the endophytic fungi of Chinese fir is only carried out on the identification of the root, but the research on the endophytic fungi is not involved in the leaves and stems of Chinese fir.

In addition, there is still a gap in the research on the influence of endophytic fungi on the growth of Chinese fir itself.
