Abstract

It has been observed in previous studies that Easter lilies grow taller at lower light intensities. From data recently collected at the Los Angeles campus, it was also found that closer spacing is equivalent to lower light intensity insofar as height is concerned. The data summarized in the graph indicate that plants from commercial-size bulbs were of minimum height when 100 sq inches or more were allowed per plant. At higher light intensities, this critical value would be expected to be lower and at lower intensities, higher.–Harry C. Kohl, Jr., and R. L.
