STUDY ON EFFECT OF LIGHT RARE EARTH-ISOLEUCINE CHELATE ON HERICIUM ERINACEUM GROWTH
Abstract
Today, the use of rare earth elements (REE) as trace nutrients in agriculture including plants and animals is widely practiced in some countries. In general, it is known that many organic compounds of REE are capable of influencing many physicochemical and biologicalprocesses taking place in the root-soil interface, such as uptake of nutrients by plants as well as microbe interactions.
This paper dealt with the effect of light rare earth elements (REE) isoleucine chelates on the growth of Hericium erinaceum mushroom at the different total rare earth concentrations. In our experiments, mixed light REE isoleucine chelates were applied in order to evaluate its potential.
The obtained results showed that light REE isoleucine chelates have significant good effect on mycelia growth of this mushroom. The growth of Hericium erinaceum mushroom was stimulated when total rare earth element contents reached 100 ppm - 200 ppm. When REE contents were higher than 300 ppm, the growth of mushroom was inhibited.
