Abstract
The study was conducted to determine the effects of Arbuscular Mycorrhizal Fungus (AMF)applications on resistance levels of some selected from Van Lake Basin local melon genotypes that werepredetermined resistant situations against to the Fom 1 race of Fusarium oxysporum f.sp. melonis . In studycarried out at Selçuk University, Agricultural Faculty Experimental greenhouses and laboratories, 65 MUR 01,65 ERD 06, 65 EDR 03, 13 TAT 01, 65MER 06 and 65 EDR 02 melon genotypes were used as plant material;Glomus intraradices (G. intraradices) and Gigaspora margarita (G. margarita) were used as mycorrhizal fungi.In experiment, the ratios of 1:2:2 sand, garden soil and farmyard manure were used as growth media. To protectthe diseases associated from soils and naturally presence of mycorrhizal problems, growth media was irrigatedwith distilled water. The each plots had the 15 pots with a capacity of 250 ml and there was only one plant in eachpot. The experiment was ended after the 40 days from seed sowing. The five plants were taken from each plot forfusarium test and they were put on 30 days observation in laboratory. In the control plots, from various sensitivegenotypes, 65 MUR 01, 65 EDR 03, 13 TAT 01 and 65 MER 06 numbered genotypes never became ill in the G.intraradices application. Moreover, 65 MUR 01, 65 ERD 06 and 13 TAT 01 numbered genotypes never became illin the G. margarita applications. It was indicated G. intraradices mycorrhiza species had generallythe best effectin increasing level of tolerant to Fom 1 .
