Abstract

A colonization test was carried out to evaluate the potential of dried banana leaves (BL) for growth of edible mushrooms. Banana leaves were used singly or mixed with corn cobs (BLCC)(70:30) and sugar cane bagasse (BLSB) (50:50). Wheat straw (WS) was used as control substrate. Three different species of the genus Pleurotus were tested, namely: Pleurotus sp. ''Florida'', P. ostreatoroseus and P. sajor-caju. The driedwastes were chopped into particles of about 0.5 cm in length, rehydrated to reach approximately 70% moisture content and sterilized in petri dishes at 120 degrees C for two hours. The pH values were 7.0 for BLand WS, 6.3 for BLSB and 7.4 for BLCC, not requiring further disownment. Experiments were performed in triplicate for each substrate/taxon combination. After sterilization, the substrates were inoculated with a colonized disk culture (1.0 cm) and incubated for 12 days at 25+/-1 degrees C. Radial growth was measured every four days in parallel witha visual evaluation of mycelial vigor. All the substrates supported mycelial growth of the cultures tested. Considering the average radial growth, its lowest standard deviation and mycelial vigor, the best results were obtained with BL inoculated with P. ostreatoroseus or P. sajor-caju and with BLCC inoculated with P. sp. ''Florida'' or P. ostreatoroseus. For substrate BLSB, optimum growth was generally associated with lower mycelial vigor. The control substrate (WS) showed the smallest radial growth and highest mycelial vigor for all the cultures tested.
