Abstract: 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 25oC±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 strainLE-96/18 presented the fastest mycelial growth after incubation for ten days, regardless of sawdust extract type used in the culture medium. Avaliou-se o crescimento micelial in vitro das linhagens LE-95/01 e LE-96/18 de Lentinula edodes, em meios de cultura sólidos à base de extrato de serragem de sete espécies (Eucalyptus saligna, E. grandis, E. urophylla, E. pellita, E. paniculata, E. citriodora e E. camaldulensis) e três clones (híbridos de E. grandis x E. urophylla) de eucalipto. As avalia es foram realizadas por meio de medi es do diametro das col nias (média de quatro medidas diametralmenteopostas), a cada 48 horas, durante dez dias de incuba o, no escuro a 25oC ±1°C. O delineamento experimental foi o de blocos casualizados, com uso do teste de Tukey para a compara o das médias. O meio de cultura à base de extrato de serragem de E. citriodora foio mais promissor no crescimento das linhagens LE-96/18 e LE-95/01 de L. edodes. A linhagem LE-96/18 de L. edodes foi a que apresentou o crescimento micelial mais rápido após dez dias de incuba o, independentemente do tipo de extrato de serragem utilizado nomeio de cultura.

Abstract: Avaliou-se o crescimento micelial das linhagens de shiitake LE-95/01, LE-96/18, LE-96/13, LE-98/55, LE-98/47, LE-95/02, LE-95/06 e LE-95/07, a sua produ o em toras de eucalipto e as conseqüentes altera es em características físicas da madeira em decorrência da inocula o com a linhagem LE-96/18. O crescimento micelial foi avaliado em meio de cultura SA (serragem enriquecida com farelo-ágar) a 25°C. No cultivo em toras, cada linhagem foi inoculada em 40 toras de Eucalyptus grandis com 1 m de comprimento e 9 a 14 cm de diametro. As toras foram mantidas em estufa climatizada, com temperatura de 25°C ± 3 e umidade relativa entre 75-90%, durante 6 meses. Em seguida, foi realizado um “choque de indu o”, seguido da produ o de basidiomas. Verificou-se que: (1) a linhagem LE-95/01 obteve as maiores produ es, mesmo tendo crescimento mais lento no teste in vitro; (2) houve crescimento lento da linhagem LE-95/06 in vitro e baixa produ o de basidiomas; (3) o teor de umidade das toras inoculadas com a linhagem LE-96/18 sofreu aumento ao longo do cultivo, enquanto a massa específica sofreu diminui o. The growth rate of 8 strains of shiitake (LE-95/01, LE-96/18, LE-96/13, LE-98/55, LE-98/47, LE-95/02, LE-95/06 and LE-95/07), the production of these in Eucalyptus logs at the first flush, and consequent alterations in physical characteristics of the wood due the inoculation with the strain LED-96/18 were evaluated. The mycelium growth was inoculated in SA medium (sawdust enriched with crumb-agar), in the absence of light, at 25°C. In log cultivation, each strain was inoculated in 40 logs of Eucalyptus grandis with 1 meter length and 9 to 14 cm of diameter. The logs were maintained at 25°C ± 3 and relative humidity of 75-90%, for 6 months. Subsequently, the first flush was accomplished, and it was verified: (1) the lineageLE-95/01 obtained the largest production and slower mycelium growth in vitro; (2) there was slow growth of the strain LED-95/06 and low mushrooms production; (3) the moisture of the logs inoculated with strain LE-96/18 increased along the cultivation, whereas the specific mass decreased.
