Abstract
This study was conducted to clarify the effects of various rhizobacteria in the root zone in terms of Azospirillum sp., Rhodopseudomonas sp., Pseudomonas sp., fusant of Bacillus sp. and Corynebacterium glutamicum on the growth of hydroponically grown cucumber plants. Densities in bacterial cells of fusant of Bacillus sp. and Corynebacterium glutamicum at different substrates were in the order of cocopeat > rockwool > nutrient solutions at 4 days after bacterialization. Plant growth promoting effects of the various rhizobacteria on the growth of hydroponically grown cucumber plants were in the order of Azospirillum sp. > Rhodopseudomonas sp.
수종의 근권세균이 양액재배 오이의 생장에 미치는 영향을 구명하기 위하여 Azospirillum sp., Rhodopseudomonas sp., Pseudomonas sp., Bacillus sp.와 Corynebacterium glutamicum간의 융합균주 등을 근권처리하였다. 융합균주의 근권처리후 4일에 세균의 밀도변화르르 보면 코코피트 > 암면 > 배양액 등의 순으로 나타났다. 균주의 근권처리에 따른 오이의 생장촉진효과는 암면경보다 코코피트경에서 더 높았으며, 균주의 종류별 오이의 생장촉진효과를 보면 Azospirillum sp. > 광합성세균
