Effects of sugars on germination and mycelium growth of Fusarium Oxysporum

In earlier study, carbohydrates content and types were isolated and identified in root exudates of different cucumber cultivars. The soluble sugars (glucose and sucrose) in root exudates increased with the resistance to Fusarium oxysporum. Thus we studied the effects of application of different concentrations of exogenous glucose and sucrose (to simulate the soluble sugar content in root exudates from different cucumber cultivars) on spore germination, mycelial growth and mycelial biomass of Fusarium oxysporum. The applied sugars (glucose and sucrose) stimulated the spore germination and mycelial growth of mycelium of Fusarium oxysporum and the stimulation was concentration dependent.
