In studies of the influence of optimal substratum composition on mycelia growth and fruit-body formation in Flammulina velutipes it was found out: the highest lineal daily mycelia growth rate was achieved on cultivating media from wheat straw (0.51 mm) and shredded corn cobs (0.50 mm). Cultivated on unsupplemented media the best yields were achieved on corn cobs (20.97%) and wheat straw (19.13%). The best yields were obtained from F. velutipes cultivated on corn cobs supplemented by a mixture of 10% bone meal and 12% wheat corn meal (28.4%). Evaluating the influence of different methods of cultivation on yield the following was found out: the optimal duration of media incubation by mycelia in supplemented corn cobs was 21 days, whereas in unsupplemented mixture sawdust:straw:corn cobs (ratio 1:1:1) the best yield was achieved after 35 days of incubation. By the reduction of the yielding surface by 2/3 a substantial increase in the average weight of fruit-bodies was obtained with a slight drop of yield as compared with plots with unlimited yielding surface. Sterilized media gave a yield which was higher by 1% than pasteurized ones.
