Cultivation of the Edible mushroom Oudemansiella Canarii (Jungh.) HÖhn. in Lignocellulosic substrates

ABSTRACT

The edible mushroom Oudemansiella canarii (Jungh.) Höhn is common in the Brazilian territory, being found in different biomas, where they colonize several plant species. In this study, the O. canarii cultivation was evaluated in polypropilene bags containing sugar-cane bagasse (200 g) or eucalyptus sawdust (200 g) supplemented with wheat bran (50 g). The composts were sterilized at 121§C for 1 hour, after cooling they were inoculated with 3 g of spawn and then remained incubated at 25§C until the basidiomata primordia formation. The mushrooms, harvested after the pilei opening, presented varied sizes reaching 9 cm of diameter and 10 cm of height. The fresh mushrooms presented mild taste and soft consistency. When kept at 4§C, they maintained good appearance and good consistency for 7 days. In a period of 60 days, the largest basidiomata production was obtained in the compost with sugar-cane bagasse, showing greater productivity (4.47per cent ñ 1.34), biological efficiency (55.66per cent ñ 20.41) and compost consumption (38.78per cent ñ 4.59) averages. Wilcoxon's non-parametric statistical analysis used to compare the biomass production in the two composts, showed significant differences at 5 per cent significance level.
