| Abstract:
Arisaema sikokianum is one of the most beautiful Arisaema species native to Japan. A. sikokianum produces 300 to 1100 seeds per spadix. The fruit color is green to pale yellow in November and changes to orange and finally to red in December. Seeds harvested in November show low and slow germination. On the other hand, faster and higher rate of germination is observed when seeds are harvested in December and stored for more than one month at room temperature. Both chilling and GA treatments are effective in enhancing germination. Optimal temperature for seed germination is 15-25C under dark conditions. | |
