Abstract
Givotia rottleriformis is an economically important forest deciduous tree species. Its wood supports a carving industry. Propagation of this species is mainly through seed. But the seed germination is very poor. Seed exhibit dormancy for one to two years. It is attempted to find various individual phenolic acids and its related enzymes in all parts of the seed to correlate the data with dormancy. Phenolic acids were identified and estimated in pericarp, mesocarp, endocarp and endosperm of ripen and dried seeds of Givotia rottleriformis. Total phenolic acid content and associated enzymes namely polyphenol oxidase and peroxidase activities was more in mesocarp followed by pericarp, endocarp and endosperm. Out of ten phenolic acids identified in different components of seed, only five phenolic acids such as protocatechuic acid, p-hydroxybenzoic acid, cinnamic acid, syringic acid, and caffeic acid are commonly present in all seed parts of Givotia rottleriformis. Total phenolic acid content and associated enzymes varies from part to part of a seed.
