Abstract

Hard testa creates severe difficulties for the germination of seeds. One of the causes of low germination is a rigid and waterproof seed testa. In practice, the seeds are treated by different kinds of physical or chemical agents before sowing to destroy the solid testa. In this paper, the following techniques were used before germination to improve the germination of seeds with a hard testa, such as scarification, stratification, treatment by boiling water, influence of pulse pressure and treatment of seeds with acetone. Suberin is a component of the hard seed coat; it is a highly polymeric hydrophobic substance, which contains saturated and unsaturated fatty acids and fats as essential components. We proposed that suberin partially dissolves in acetone, resulting in increased permeability of the seed coat for water. The presence of lignified elements, suberin, and polysaccharides in the seed coat was confirmed by histochemical methods. The structure and chemical composition of the seed coat of the honeylocust were searched.
