Abstract

본 연구에서는 가지과 작물의 근권에서 유용한 균주를 분리하고 근권ㆍ길항ㆍ생육촉진미생물을 선별ㆍ제제화하고 상토에 첨가하여 미생물제제 혼입 상토를 제조한 후 고추 플러그묘의 초기 생장에 미치는 영향을 조사하였다. 근권미생물로는 가지과 작물의 뿌리 및 재배 토양 등 385점의 균원시료로부터 540여점을 분리한 후, 가지과 작물에 공통적으로 발생되는 Alternaria solani, Botrytis cinerea, Fusarium oxysporium, Phytophthora capsici, Sclerotinia sclerotiorum 등의 병원균에 높은 길항력을 가진 미생물 20여종을 선발하고, 이들 길항미생물 중에서 고추의 초기 생육을 촉진시키는 MJ-3균주를 최종 선발하였다. 근권ㆍ길항ㆍ생육촉진미생물인 분리주 MJ-3은 Bergey's manual of systematic bacteriology의 방법과 16S rDNA sequence법 등으로 조사하여 Bacillus amyloliquefaciens동정하였다. 제제화한 B. amyloliquefaciens를 상토에 첨하여 미생물 혼입 상토를 제조하였고, 이를 이용하여 재배한 고추 플러그 묘는 초장과 경경, 뿌리길이, 생체중량 등이 모두 대조구에 비해 소량 증가되었으나, 특히 뿌리의 생체중량이 대조구가 0.61g/plant인데 비해 시험구는 0.88g/plant로 44.3% 증가하였다. 미생물제제 첨가 상토에서 재배한 고추의 gib-berellin (GA$_1$) 함량은 0.559ng/g(건조중량)이었다. The effect of useful rhizobacterium added in bed soil on the early growth promotion of red pepper plug seedlings was investigated. Total 540 colonies of rhizobacteria from 385 samples of eggplant family roots were isolated. Among these, 5 isolates were selected for antifungal activity against pathogenic fungi such as Alternaria solani, Botrytis cinerea, Fusarium oxysporium, Phytophthora capsici, and Sclerotia sclerotiorum. Of all the isolates, MJ-3 having the most pronounced growth-promoting ability for red pepper was finally selected and identified as Bacillus amyloliquefaciens through characterization of biochemical and bacteriological aspects and 16S rDNA sequence. The plant height, stem diameter, root length and fresh weight of red pepper plants which were grown with inoculation of B. amyloliquefaciens MJ-3 were higher than those without inoculation. Especially the root weight of the inoculated red pepper plant increased by 44.3%, the content of endogenous plant hormone (CA$_1$) being 0.556 ng/g (dry weight).
