Abstract
Among 110 isolates of actinomycetes isolated from ginseng pathogen-suppressive soils, the three actinomycetes showing the effective controls to Fusarium solani or Cylindrocarpon destructans causing ginseng root rots were identified according to their morphological, cultural and physiological characteristics on various culture media. Spore chains of K 6-2, S 2-1 and Y 2-2 were Spira (S), Retinaculum-apertum (RA) and Rectus-flexibilis (RF), respectively. Spore surfaces of K 6-2 were spiny, whereas S 2-1 and Y 2-2 were all smooth. Aerial mass colors of 3 isolates were gray series. As a result of various tests, they were identified as Streptomyces variabilis, Streptomyces virginiae and Streptomyces griseo/us, respectively.
인삼병원균(人蔘病原菌) 억제토양(抑制土壤)으로부터 110종(種)의 방선균(放線菌)을 분리(分離)하여 인삼근부(人蔘根腐) 병원균(病原菌)인 Fusarium solani와 Cylindrocapon destructans에 길항효과(拮抗?果)를 나타내는 3종(種)의 방선균(放線菌)이 형태적 배양적 생리적인 특정에 의거하여 각각 분류동정(分類同定)되었다. 포자사슬의 모양은 강화 6-2(K 6-2) 가 감긴형태 (Spira)였고, 서울 2-1(S 2-1)은 고리형태(Retinaculum-apertum)였으며, 양주 2-2(Y 2-2)는 꾸불꾸불한 형태(Rectus-flexibi-lis)였다. 포자벽 표면의 모양은 강화 6-2(K 6-2)에 서는 바늘모양의 형태(Spiny)인 반면, 서울 2-lCS 2- 1)과 양주 2-2(Y 2-2)에서는 모두 매끄러운 형태(Smooth)였으며, 기생균사체의 색깔은 모두 회색(灰色)계통이었다. 따라서, 강화 6-2(K 6-2), 서울2-lCS 2- 1), 양주 2-2(Y 2-2)는 Streptomyces variabilis, Stre-ptomyces virginiae, Streptomyces griseolus로 각각 분류동정(分類同定)되었다 .
