The present study investigates the germination requirements of the seeds of Cryptomeria japonica with respect to temperature, light and gibberellic acid. The study indicates that temperature optima of 22°C, darkness and GA3 (25 mg l−1) are factors promoting germination of this species. Poor germination at high temperature under both light and dark conditions may be an indication of thermo sensitive nature of this species.
