Effect of a suitable combination of 1-naphthaleneacetic acid (NAA) and cytokinin N-(2-chloro-4-pyridyl)-N'-phenylurea (4PU30) concentrations, regarding organ differentiation and dihydroisocoumarin production, was examined in Hdrangea macrophylla var. thunbergii callus cultures. The callus cultured in a Linsmaier-Skoog medium containing 10-5 M NAA and 10-5 M 4PU30 under a light condition gave the highest level for callus growth, shoot formation, and phyllodulcin 8-O-glucoside content.
