Original Paper

The production of procyanidin and anthocyanin in grape cells is markedly increased by treatment with salicylic acid. The activity of phenylalanine ammonia-lyase and chalcone-flavanone isomerase increased in close relation to the production of these phenolics. Salicylic acid-induced elevation of these enzyme activities occurred more rapidly than elevation induced by light irradiation. In the cells, the phenolics were degraded in a different manner by salicylic acid treatment than that by light irradiation. Salicylic acid might be used as a simple and effective stimulant for the production of procyanidin as well as anthocyanin in large scale cultures of plant cells.
