Germination of the seeds of Trochodendron aralioides SIEB. et ZUCC. was investigated for six temperature conditions. Germination was 91.7 % at 28℃, but percentages ranged from 27% to 37% at lower temperatures of 23℃, 18℃, and 13℃. Germination was 81 % at the daily alternating temperatures of 20℃ for 16 h following by 30℃ for 8 h, but only 9 % was realized at an alternation of 10℃ and 20℃. Seeds stored at 0 to 3℃ for four or eight weeks before these germination conditions achieved more than 97 % under every temperature condition. Without light, the seeds did not germinate at the constant temperatures, and only about 2 % of the pretreated seeds germinated at the two sets of alternating temperatures.
