Silicon Reduces the Severity of Fusarium Infection on Young Wheat Parts In Vitro

Background: Although silicon (Si) has been referred as an essential element for controlling destructive diseases of wheat, available data are limited about enhancing adult wheat resistance against Fusarium causing head blight. Also, no reports seem to exist on the use Si reduce seedling blight (FSB) young parts in vitro . Under conditions, infection happened at stage cannot be called blight, because it is not a “head” disease, instead could “FSB”. Objective and Methods: This research aimed elucidate bio-efficacy soluble 1.7 mM increase FSB measured by latent period (LP) detached leaf inoculation, area under disease progress curve (AUDPC) Petri-dish inoculation coleoptile length reduction (CLR) detected treatments were applied six bread durum cultivars contrasting susceptibility infected with four species displaying diverse pathogenicity. Results: Differences observed leaves seedlings Si- -inoculated relative fungal-inoculated-controls, showing beneficial role played this decreasing symptoms plant conditions. In all different species, application did host ; resulted significantly higher LP lesser AUDPC CLR compared controls. More importantly, increased susceptible moderately LP, same level exhibited cultivar high quantitative without Si. Conclusion: first report presenting utility three distinct bio-assays investigate effect wheat- pathosystem. The complement appears effective strategy management wheat.
