Quality parameter changes in wheat varieties during storage at four different storage conditions

Summary Changes in seed quality parameter of three wheat varieties during one year storage at four diff erent storage conditions, were studied. Applied storage conditions adversely aff ected quality changes in wheat seeds during one year storage. Th e most pronounced changes were observed for seeds kept at 40°C, RH = 45%, followed by seeds stored at 25°C, RH = 45%, while seeds kept at 4°C, RH = 45% or at warehouse conditions mostly showed minimal or statistically insignifi cant changes. Elevated temperature of seed storage caused a signifi cant decrease of starch content, hectolitre weight, and wet gluten content, accompanied with increase in fl our acidity, and fl uctuating in Zeleny sedimentation value. Th e intensities of observed changes showed strong dependence on wheat variety.
