| Abstract: | Supplemental light applied to potato seedlings grown under winter conditions in the greenhouse increased both the size of the largest tuber produced per plant, and the total weight of tubers per plant. The application of supplemental light for a period of 30 days following pricking-off produced a tuber three times the weight of any tuber from the control, and this tuber size was not exceeded by other treatments ranging up to 120 days of applied supplemental light. |
