An endophytic fungus that can improve the photosynthesis of Chinese fir

Abstract

The invention relates to an endophytic fungus capable of improving the photosynthesis of Chinese fir. Described endophytic fungus is spinosa ( Colletotrichum sp. ) AJ4, which was registered and preserved on May 20, 2014 in the General Microorganism Center of China Microbiological Culture Collection Management Committee, and the preservation number is CGMCC? No.9227. By using the bacterium solution of the strain, the root dipping of Chinese fir seedlings in the early planting period and the root watering of Chinese fir forest can be performed. The bacterial strain involved in the present invention is tested through the determination of the plant after inoculation, and the chlorophyll content and chlorophyll fluorescence parameters of the plant are better than the control, and the inoculation method of watering the root is better than that of the crown, which shows that it has greatly improved the photosynthesis of Chinese fir. effect.

Description

technical field [0001] The invention relates to an endophytic fungus capable of improving the photosynthesis of Chinese fir. 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 resista...

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.
