Untersuchung der Qualität von Saatgut sowie der Wurzel- und Sprossentwicklung von Getreidekeimlingen

Primary roots and shoots of 13 day old cereal seedlings and quality of seed were investigated in the frame of the certification process of organic seed produced in Austria. The germination of seed and the development of seedlings were significantly affected by Microdochium nivale on wheat, triticale and rye and by Septoria nodorum on wheat. The number of primary roots was found to be significantly different in wheat varieties and genotypes but was not influenced by year and region. The number of primary roots was also positively correlated with the kernel weight of some wheat varieties
