Abstract
When pullulan is used as a binder in coating seeds with inorganic materials, growth hormone preparations, etc., a satisfactory binding effect is obtained with smaller amounts than when conventional binders are used. The resulting inorganic coatings on the seeds are superior in surface hardness and disintegration characteristics in the soil after sowing. Germination of the seed and subsequent growth are not affected by pullulan. Chemically modified pullulan can also be used.
