Developmental characteristics and domestication of Gerronema lapidescens
摘要
Abstract
The development characteristics at different growth stages of fruiting bodies of Gerronema lapidescens(Chinese medicine name:Leiwan)were observed under different cultivation substrates,light intensities and planting seasons to determine the optimal conditions for domestication and cultivation of the fungus.The observation showed that in the process of fruiting body formation,the mycelium initially interweaved into a rice-like primordium,and then the primordium elongated and thickened to form a white columnar fruiting body.Subsequently,the central part of the tip of the column expanded and differentiated into a hemispherical black cap.With the cap colour lightened and cap volume increased,basidiospores were produced and a mature fruiting body formed.In the process of sclerotium formation,mycelium first aggregated and twisted into bundle to form rhizomorph,and the end of the rhizomorph sprouted white mycelial cluster with a relatively loose structure.With the density of the mycelial cluster increased,the volume expanded and the epidermal colour changed from light to dark,and finally the mycelial cluster gradually formed a mature sclerotium and detached itself from the rhizomorph.The cultivation experiment showed that the culture medium containing wood chips(87.7％),cornmeal(5.0％),wheat bran(5.0％),soybean meal(1.0％),gypsum(1.0％),MgSC4(0.1％),and KH2PO4(0.2％)resulted in the fastest mycelial daily growth rate and the most vigorous growth,suggesting that it is the optimal cultivation formula.The higher environmental temperature in August was the optimal time for artificially inducing the formation of fruiting bodies.The morphology of the fruiting bodies approached the wild state under light intensity of 700 1x.关键词
