Cultivo de Lentinula edodes em diferentes condições de substrato e temperatura

Abstract

The productivity of Lentinula edodes (Berk.) Pegler is influenced by several factors: lineage types, temperature, formulation of the cultivation substrate and competition with other fungi. The objective of this work was to evaluate the biological efficiency (BE) of five lineages of L. edodes (Le1, Le2, Le3, Le4 and Le6) in function of two environments: one with controlled temperature and the other without temperature control; of the substrate type: there were 3 formulations with varied concentrations and the types of meal used as supplement; and of the sawdust pre-treatment: two formulations with washed sawdust and the same formulations with unwashed sawdust. According to the results obtained, it was verified that BE was better for all of the lineages in the substrate with higher meal concentration, however regarding the 2 cultivation environments, the controlled temperature environment was better for Le2, Le3 and Le6, with 79.55, 75.81 and 82.3% of EB respectively. Le1 presented the same BE (78.6) in the two cultivation environments, while Le4 presented better performance in the environment without temperature control with 83.14% EB. There was no difference in BE between the washed and unwashed sawdust for each block that produced mushrooms, however the treatment with washed sawdust had lower contamination, in other words, when considereing the total production, the use of washed sawdust allows higher production.
