Optimal light for greenhouse culture of American ginseng seedlings

Three greenhouse experiments with American ginseng seedlings growing under light levels from 4.8% to 68% showed a quadratic response for root dry weight, giving an optimal root dry weight of 239 mg (range 160–415 mg) at an optimal light level of 35.6% (range 30.6–43.2%).
