Nghiên cứu tác động của các phức vòng càng giữa các nguyên tố đất hiếm nhẹ và isolơxin tới sự tăng trưởng của nấm Hericium Erinaceum | TẠP CHỈ KHOA HỌC VÀ CÔNG NGHỆ Tập 47 số 5 2009 Tr. 27-32 STUDY ON EFFECT OF LIGHT RARE EARTH - ISOLEUCINE CHELATE ON HERICIUM ERINACEUM GROWTH LE MINH TUAN NGUYEN THI CHINH NGUYEN TRONG UYEN NGUYEN DINH BANG 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 biological processes 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 eriiiaceum 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. Key words. Hericium erinaceum rare earth elements chelate L-isoleucine. 1. INTRODUCTION Rare earth elements REE and their compounds are widely applied in agronomic and medical fields for many years. The bioinorganic chemical research of REE during the past years indicates that REE play important roles in the promotion of photosynthetic rate as well as root absorption regulation of hormone and nitrogen metabolism and suppression of microbes etc 1 - 3 . The metallic or non-metallic targets of key biomolecule in various physiological processes can be chosen by REE for the chelation or replacement which enables REE to regulate the biological functions or behaviors of those biomolecule and consequently leads to significant embodiment of biological function of REE in plants
