Abstract
This study was carried out to establish of hydroponic culture system for year-round mass production of yam and for supply of disease-free seed tubers from the superior yam species. There were not difference in tuber weight between 9 hrs photoperiod(640mg) and natural photoperiod(600mg). However, longer photoperiod than 9 hrs such as 12 hrs and 15 hrs decreased tuber weight to 490 and 500g, respectively, which sugested that long photoperiod showed adverse effect for tuber enlargement. Tuber enlargement of Dioscorea opposite according to ionic strength was higher at 50% nutrient of Sanyak's standard solution. The optimal concentration of NAA for the best tuber growth showed at 100mg/L as a 560mg while control showed a relatively lower tuber growth(350mg).
