LIU Xing-rong CHEN Fang-cao TAN Fang-he LIN Qiang(Sichuan Academy of Forestry,Chengdu 610066)  
Researches were directed towards experimental conditions of two important morel strains A and B,such as sizes of petri dishes,different temperatures,C and N sources,trace elements,pH,various concentration of KH 2PO 4 and MgSO 4,temperature changes etc.The appropriate conditions of sclerotium production and the cultural characteristics of different strains in petri dishes were also observed in detail.The results showed that the optimal temperatures ranged from 15℃ to 20℃ for strain A and from 20℃ to 25℃ for strain B and the pH range was between 5 and 7 for both of the two strains.The various C sources and N sources could be used by the two strains with glucose and sucrose being the best C source and peptone and yeast being the best N source.KH 2PO 4 and MgSO 4 played an important role in sclerotium production while there was no obvious need for trace elements.And the petri dish size fitting for sclerotium production was 9.0 cm.
