Impaired Anthocyanin Production in Barbiturate treated Zea mays Seedlings

Anthocyanin production was impaired in both roots and shootsof Zea mays seedlings germinated on 1 and 2 mM concentrationsof four barbiturates having different lipid/aqueous partitioncoefficients. The severity of impaired anthocyanin productionwas greater in those seedlings treated with the higher lipidsoluble barbiturates irrespective of the concentrations used.Indirect evidence is presented which indicates that barbituratesinterfere with normal membrane physiology responsible for anthocyaninproduction.
