TAILIEUCHUNG - In vitro inhibition of the mycelial growth of some root rot fungi by Rhizobium leguminosarum biovar phaseoli isolates

In solid medium, the effects of twenty-three Rhizobium leguminosarum biovar phaseoli isolates on the mycelium development of the phytopathogenic fungi of three different genera (Fusarium oxysporum, Pythium ultimum and Rhizoctonia solani) were tested in vitro. | Turk J Biol 25 (2001) 435-445 © TÜB‹TAK In Vitro Inhibition of the Mycelial Growth of Some Root Rot Fungi by Rhizobium leguminosarum Biovar phaseoli Isolates ‹brahim ÖZKOÇ, Muhammet Hanifi DEL‹VEL‹ Ondokuzmay›s University, Faculty of Arts and Sciences, Department of Biology, 55139, Kurupelit, Samsun - TURKEY Received: Abstract: In solid medium, the effects of twenty-three Rhizobium leguminosarum biovar phaseoli isolates on the mycelium development of the phytopathogenic fungi of three different genera (Fusarium oxysporum, Pythium ultimum and Rhizoctonia solani) were tested in vitro. The experiments were achieved by applying the superimpose dual culture technique. Most of the rhizobia tested inhibited the fungal development. The inhibition rates displayed differences in accordance with the bacteria and fungi isolates utilized. However, the inhibitory effect of the rhizobia occurred most on the isolates of Fusarium and Pythium species (up to and respectively) and least on those of Rhizoctonia species (). The most effective Rhizobium isolate on the three fungal species was Rhizobium leguminosarum Çar isolate and percent inhibitions were for R. solani isolates and for P. ultimum isolates and also for F. oxsporum isolates.
