ERM fungus Hyaloscypha hepaticicola on Rhododendron aureum in Changbai Mountains and its biological characteristics
摘要
Abstract
Rhododendron aureum is one of the dominant plants in the tundra belt of Changbai Mountain Nature Reserve.In order to adapt itself to the environmental conditions of infertile soil and cold climate in the tundra of the mountains,R.aureum evolves a special ericoid mycorrhiza(ERM)with some soil fungi,which plays a key ecological role in the plant survival and propagation.Two isolates of ERM fungi were screened from the roots of R.aureum in the tundra of Changbai Mountains,and they were identified as Hyaloscypha hepaticicola by morphological observation and ITS sequence analysis.The study of the biological characteristics showed that the optimum culture conditions for this fungus were as follows:using glucose as carbon source and yeast powder as nitrogen source;cultivation at temperature of 20℃ and pH value of 4 under dark condition.This ERM fungus has adopted well to the relatively low temperature and acidic soil environment of the tundra of Changbai Mountains.Further in-depth investigation and economical utilization of H.hepaticicola and other related ERM fungi will be continued.关键词
