Cultivo do champignon em função da temperatura

The Agaricus bisporus is a button mushroom that requires low temperature to induce fruiting. This requirement limits our cultivation in Brazil during the coldest months of the year and requires the use of controlled environment. Therefore, this study aimed to assess the productivity of different strains depending on the growth temperature after induction of fruiting. A. bisporus strains were evaluated for the effect of temperature on the colonization of compost and mushroom productivity. Temperatures of 21 and 25°C were used for the substrate colonization and after induction of fruiting crop cycle. For all strains tested, temperature 25°C gave a quickly colonization of the compound, favoring shorter production cycles. Furthermore, after induction of fruiting at 18°C, maintaining the culture environment at 25°C gave a higher productivity to contrast with culture at 21°C. For the most productive strain, the first three streams were responsible for over 50% of total production. Thus, for a cash crop where it is necessary to maintain constant volumes of production, crop cycles could be limited to three productions flows.
