Seed germination of sweet pepper (Capsicum annuum L.) is inhibited after the seed is coated. The inhibitory effect of pellet-coating of 'Early Calwonder' pepper seed was caused by the physical properties of the coating materials. Clay coating limited part of the oxygen (02) from reaching the germinating seed and provided a mechanical barrier to protrusion of the radicle. Clay-coated pepper seed germinated satisfactorily on filter paper in a high 0 2 environment or with minimum moisture on agar. Pellet coating formulations which would provide more 0 2 to the imbibing seed would assure comparable germination of raw and coated sweet pepper seed.
