Description
Summary:A preliminary study was carried out for the effect of far UV radiation on the morphology and germination of the conidia of Fusarium culmorum . It can be established that the UV radiation was effective mainly on the width and the number of transversal walls of conidia developed on the air mycelia. For the examination of the effect of UV radiation, conidia were prepared from the irradiated mycelia as well as from the mycelia developed after the irradiation. As a result of our investigations, it can be established that the conidia developed in the mycelia irradiated by 0,81 J/cm 2 dose were resistive for the far UV radiation. The germination percent of these conidia were about 20 percent even at the dose of 1,728 J/cm 2 applied at the start of germination. The conidia isolated from mycelia developed after irradiation already lost their ability of germination at the irradiation of the smallest dose.
