Studies on Rhizosphere and Rhizoplane Microflora of Tomato (Lycopersicon esculentum Mill) Seedlings
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 3, Issue 7
Abstract
Investigations were carried out on the rhizosphere and rhizoplane microflora of tomato (Lycopersicon esculentum) seedlings planted in Amugwu village of Obige Obukpa in Nsukka Local Government Area of Enugu State, Nigeria. The rhizosphere and rhizoplane microflora of tomato seedlings were isolated and identified. Isolated bacteria were Bacillus subtillis, Proteus vulgaris, Citrobacter sp. and Erwinia sp. The fungi isolated from the rhizosphere were Trichoderma lignorum, Rhizopus stolonifer, Aspergillus niger, Penicillium oxalicum, Sclerotium rolfsii while R. stolonifer, S. rolfsii, T. lignorum, A. niger and Fusarium solani. Some of these organisms were more predominant in the rhizosphere while some were more predominant in the rhizoplane. The rhizosphere soil contained a great spectrum of bacteria whereas there were no bacteria isolated from the rhizoplane. Also, fungi were more abundant in the rhizosphere than in the rhizoplane. The rhizosphere and rhizoplane microflora increased with plant age but declined after about twelve weeks.
