Effect of buprofezin on the formation and reversion of protoplast from mycelia of Pleurotus ostreatus and P. sajor-caju

Buprofezin이 느타리버섯속의 원형질체 나출 및 재생에 미치는 영향

Effects of buprofezin, an inhibitor of chitin synthesis, on mycelial growth, protoplast formation and reversion of Pleurotus ostreatus and P. sajor-caju were investigated. The mycelial growth of Pleurotus ostreatus and P. sajor-caju was the inhibited by buprofezin treatment, and the inhibition rate was severer as the concentration of the buprofezin increased. Aerial mycelium formation was increased by buprofezin treatment, but mycelial morphology was not changed. Protoplast formation of Pleurotus ostreatus and P. sajor-caju. was significantly increased when buprofezin was added to the culture medium at the concentration of 200~500 ppm and the protoplast reversion of the mushrooms was also increased by the treatment of the buprofezin.

Chitin 합성 저해제인 buprofezin이 P. ostreatus 및 P. sajor-caju 균사의 생장과 원형질체 나출 및 재생에 미치는 영향을 조사한 바를 요약하면 buprofezin은 P. ostreatus 및 P. sajor-caju.의 균사생장을 심히 저해하였고 buprofezin의 첨가농도가 높을수록 균사생장 억제가 심하였다. Buprofezin 처리에 의하여 기균사가 증가하였으나 균사의 형태에는 변화가 없었다. 원형질체의 나출량은 buprofezin 200-500 ppm 첨가구의 균사에서 무처리보다 현저히 높은 결과를 보였고, 원형질체의 재생율은 buprofezin의 처리에 의하여 증가하였다.
