Biological characteristics of a symbiotic fungus promoting seed germination of Cremastra appendiculata
摘要
Abstract
Pseudobulbs of Cremastra appendiculata have been used as precious and rare traditional Chinese medicine.C.appendiculata seed germination depends on mycorrhizal fungi because of lacking endosperm in tiny dust-like seeds under natural conditions.A symbiotic fungus isolate DJL1 obtained from the roots of C.appendiculata was identified as Coprinellus disseminatus on the basis of morphological and molecular biological characteristics.The results of studies of the biological characteristics showed that the optimum carbon source for the mycelial growth of C.disseminatus were soluble starch,the optimum nitrogen source was yeast extract,the optimum pH was 7.0 and the optimum temperature was 25℃.This study was expected to be helpful to the future protection and utilization of C.disseminatus.关键词
