The propagation of Metaspuoia by juvenile cuttings was examined in Kyoto, Japan 1950. Cuttings were made from the lateral shoots of 1 year old plants which were donated by Prof. Chaney, California University, and are being cultivated under the supervision of Metasequoia Conservation Committee in Japan. They were made 5-10 cm long, and were inserted in a bed and placed out of doors. The propagating media were used of two sorts, Kanumatuti and sand. Results obtained are as follows. 1. As cuttings were tried 3 times, (a) on July 11,(b) on August 9,and (c) on September 7. (i). The percentage of rooted plants was higher in (a) and (b) than in (c). (ii). Arose roots per cutting were the most in (b). (iii). Callus forming rate was the highest in (c), and the relationship between callus formation and rotarising was not evident. 2. With respect to the propagation medium, arose roots were bigger in form, but fewer in number at Kanumatuti bed than at sand bed. In this study, as it concerns rare plants, we could make only a limited number of cuttings from remo ed shoots by the trimming. Therefore we shall expect studies on a larger scale in the future.
