Buprofezin이 Ganoderma및 Coriolus 속균(屬菌)의 원형질체(原形質體) 나출(裸出) 및 재생(再生)에 미치는 영향(影響)

Effect of Buprofezin Concentration on the Formation and Reversion of Protoplast of Ganoderma spp. and Coriolus versicolor

Chitin합성 저해제인 buprofezin이 Coriolous versicolor, Ganoderma lucidum, 및 G. applanatum 균사의 생장과 원형질체 나출 및 재생에 미치는 영향을 조사한 결과 buprofezin은 C. versicolor, G. lucidum 및 G. applanatum의 균사생장을 심히 저해하였고 첨가농도가 높을수록 균사생장 억제가 심하였다. Buprofezin처리에 의하여 기균사 및 oidia 형성량은 증가하였으나 균사의 형태에는 변화가 없었다. G. applanatum은 buprofezin 처리에 의하여 원형질체 나출량과 재생율이 현저히 증가하였으나, G. lucidum은 원형질체의 나출량과 재생율이 감소하는 경향을 보였으며 C. versicolor의 경우에는 원형질체 나출량이 증가하였으나, 재생율은 무처리와 차이를 보이지 않았다.

Effects of buprofezin, a chitin synthesis inhibitor of insects, on mycelial growth, protoplast formation and reversion of Coriolus versicolor, Ganoderma applanatum and G. lucidum were investigated. The mycelial growth of C. versicolor, G, applanatum and G, lucidum was severely inhibited by buprofezin treatment, and the inhibition rate severely as the concentration of the buprofezin increased. Aerial mycelia and oidia formation of the mushrooms were increased by buprofezin treatment, but mycelial morphology was not changed. The rate of protoplast formation and reversion of G, applanatum was greatly increased by the treatment of the buprofezin, while that of G. lucidium was decreased. The rate of protoplast formation of C. versicolor was also increased when buprofezin was added to the medium, but the rate of protoplast reversion was not affected by the treatment, From the results obtained in this experiment, we found that the rate of protoplast. formation and reversion was increased by the treatment of the buprofezin in the mushrooms such as C, versicolor and G, applanatum, whose mycelial growth was fast on the medium, while that of G. lucidum, whose mycelial growth was relatively slow, was decreased by the treatment.
