나도풍란(Aerides japonicum)의 변이성 protocorm 배양시 기관형성에 미치는 PVP, 활성탄소 및 배지의 무기물 조성 효과
마상희,박소영,선정훈,백기엽 한국화훼연구회 1997 화훼연구 Vol.6 No.2
The Effect of PVP, activated charcoal and mineral composition of medium on organogensis from the culture of selected off-type protocorm by the successive subculture of Aerides japonicum were investigated. High ratio of N:P:K and peptone severely decreased organogenesis especially root growth and survival rate caused by phenolic compounds exudated from plants. Though 0.5% aetivated charcoal and 0.1-0.2% PVP inhibited organogensis slightly, it prevented formation of phenolic compounds from plants and increased survival ratio. The lowest ratio of N:P:K, 5:10:5, with 0.1-0.15% as total content was the most effective for organogenesis and obtaining of healthy plants.
