Abstract

This study was conducted to investigate the effects of pathogenic hngi(Fusarium culmorurn, Fusarium oxyspomm fsp. lycopersici, Fusaiurn solani, Rhizoctonia solani), pregermination time(0, 6, 9, 12, 18, 24, 48 hrs.) and temperature($12^{\circ}C, 18^C{\circ}, $28^C{\circ}$) on growth of alfalfa seedling. The survival rate of alfalfa was decreased by pathogenic hngi and treatment of pregermination and survival rate of alfalfa resulted in higher than that of nontreatment of pregermination. Pathogenicity of fungi was increased as increased the temperature(P<0.05). The emergence rate of alfalfa was decreased when pathogenic fungi were inoculated. However, the emergence rate was increased when seeds were pregerminated(P<0.05)
