Abstract
Abstract Nutrient solutions containing concentrations of 200, 300, 400, and 500 ppm N were applied to Rosa hybrida cv. Caliente grown under either 18 hours of high pressure sodium light of 110µEm -2 s -1 quantum flux density or ambient light. Supplemental light increased yield and decreased foliar N and time to flower compared with ambient light. The lowest N level (200 ppm) produced the highest yield under ambient light, but 300 ppm N was optimum under supplemental light High N concentrations reduced stem grade under ambient light. Stem length, stem diameter, fresh weight, keeping quality, days to flower, and foliar nitrogen were not significantly affected by nitrogen treatment.
