000316 Ukoima H N;Amakiri M A (Forestry and Environment Dep, Faculty of Agriculture, , P.M.B 5080) : Fungi associated with the roots of Rhizophora mangle, Rhizophora harrisonii and Avicennia africana in Port harcourt mangrove swamp Rivers State. Ecol Envir Conserv 2007, 13(1), 39-42.
Experiment was designed to find out the percentage frequency of fungi at the rhizoplane of mangrove forest seedlings within the range 1 - 40 cm and 41 - 80 em respectively. Two experimental centres namely; Creek Road waterside and Eagle Island waterside, Port-Harcourt, Nigeria were chosen for the study. The results obtained showed that Curvularia lunata, Fusarium moniliforme. Aspergillus niger, Aspergillus flavus, Rhizopus stolonifer, Fusarium sp. and Pestalolia sp. were associated with mangrove tree seedling. At Creek road waterside the percentage frequency on the seedlings of Avicennia Africana, on heights 1-40 cm were; Fusarium sp. 19%. A, niger 17%, F. moniliforme 0%. R. stolonifer 0%, Penicillum sp. 3% and Curvularia 3%. On plants heights 41-80 cm fungi isolated were; Fusarium sp. 83%, A. niger 8%, F. moniliforme 8%, R. stolonifer 0%, Penicillium sp. 0% and Curvularia sp. 0%. On R. harrisonii; plant heights 1-40 cm, Fusarium sp. 29%, R. stolanifer 0%. Curvularia sp 3 % were found. On plant heights 41-80 cm; Fusarium sp. 0% F. moniliforme 0%, A. flavus 0%, A. niger 67% Penicilium sp. 33 %. R. stolonifer 0%, Curvularia sp. 0% were recovered. And on R. mangle, plant heights 1-40 cm, Fusarium sp. 23%, F. moniliforme 0% A. flavus 28%, A. niger 6%, Penicillium sp. 48%, R. stolonifer 3% and Curvularia sp. 7% were isolated. On plant heights 41-80 cm; Fusarium sp. 13%, F. moniliforme 13%, A. flavus 0%, A. niger 6%, Penicillium sp 31%, R. stolonifer and Curvularia sp 38% were recorded. At Eagle Island waterside the percentage frequency on A. Africana, heights 1-40 cm were Penicillium sp 46%, A. niger 19%, A. flavus 21%, Fusarium sp 0%, R. stolonifer 9% and Pestalotia sp 5%; on heights 41-80 cm; Penicillium sp 100%, A. niger, A. flavus, Fusarium sp, R. stolonifer, and Pestalolia sp 0% respectively. On R. harrisonii, heights 1-40 cm; Penicillium sp 51%, A. niger 38%. A. flavus 2%, Fusarium sp 4%, R. stolonifer 2% and Pestalolia sp 0%; on heights 41-80 cm; Penicillium sp 83%, A. niger, A. flatvus and Fusarium sp 0% respectively while R. stolanifer and Restalotia sp had 8% respectively. On R. mangle, heights 1-40; Penicillium sp 59%, A. niger 10%, A. flavus 10%, Fusarium sp 18%, R. stolonifer 0% and Pestalotia sp 3%; on heights 41-80 cm, Penicillium sp 100%, A. niger, A.flavm, Fusarium sp, R. stolonifer and Pestalotia sp had 0% respectively. These results were significant at p<60>0.05.
