Abstract

Radiosensitive dosage and morphology characterization of irradiated grey oyster mushroom Pleurotus sajorcaju by gamma rays was investigated due to effects of irradiation. In order to establish the effect, mycelium of P. sajorcaju was irradiated by gamma rays at dose 0.1 to 8.0 kGy with dose rate 0.227 Gy sec -1 . The irradiation of mycelia was carried out at the radiation facility in Malaysian Nuclear Agency. The radiosensitivity study was performed by evaluating the percentage of survival irradiated mycelia. The lethal dose of the mycelium P. sajor-caju was determined at 4.0 kGy and LD 50 to be equal at 2.2 kGy. The radiation effects on morphology were evaluated based on growth rate of irradiated mycelia, mycelia types, colonization period on substrate, morphology of fruit bodies and yields. The results shown growth rate of irradiated mycelium was slightly lower than the control and decreased as the dose increased. Irradiation was found can induced the primordia formation on PDA and the BE of irradiated seed is higher than to control. The irradiation is proven to be useful for generating new varieties of mushroom with commercial value to the industry.
