Biber (Capsicum annum L.) Bitkisinden İzole Edilen Endofitik Bakteri ve Topraktan İzole Edilen Bakterilerin Toprak Kökenli Fusarium solani, F. oxysporum, Macrophomina phaseolina ve Rhizoctonia solani’xxye Karşı Antagonistik Aktivitelerinin Belirlenmesi

Abstract

Forty-nine endophytic bacteria were isolated from pepper stem and crown and forty-nine bacteria from soil. Isolates were obtained from pepper grown fields of Bozova and Hilvan Districts of Şanlıurfa. Antagonistic effects of endophytic bacteria and soil-borne bacteria were in-vitro tested against Fusarium solani, F. oxysporum, Macrophomina phaseolina and Rhizoctonia solani in petri dishes. Bacterial isolates from soil and endophytic bacteria revealed antagonistic activity of 79.37-20.22% and 81.69-33.47%, respectively against four pathogens.Statistically significant differences were found among the efficiencies against four different pathogens. Additionally, bacteria isolated from Bozova province were found to have higher antagonistic activity than those of Hilvan province. The antagonistic activity of endophytic bacteria was found to be higher than that of bacterial isolates from soil. In later studies, effective endophytic bacteria isolated from pepper can be used against soilborne pathogens
