Crescimento micelial de duas linhagens de lentinula edodes em meios de cultura à base de extrato de serragem de sete espécies e três clones de eucalipto.

The in vitro mycelial growth of Lentinula edodes strains LE-95/01 and LE- 96/18 were evaluated in solid culture media prepared with sawdust extracts from seven eucalyptus species (E. saligna, E. grandis, E. urophylla, E. pellita, E. paniculata, E. citriodora, and E. camaldulensis) and three eucalyptus clones (E. grandis × E. urophylla hybrids). Evaluations were made every 48 hours by means of colony diameter measurements (mean of four transversely-oriented measurements), during ten days of incubation in the dark at 25°C -1°C. The experimental design consisted of randomized blocks, and treatment means were compared by Tukey test. The culture medium prepared from E. citriodora sawdust extract was the most promising to grow L. edodes strains LE-96/18 and LE-95/01. L. edodes strain LE-96/18 presented the fastest mycelial growth after incubation for ten days, regardless of sawdust extract type used in the culture medium
