Abstract

This study was conducted to investigate the effect of supplemental lighting intensity (SLI) on the shoot growth and flower quality of Rosa hybrida 'Pink Bell' in winter season. High pressure sodium lamps (HPS) which were set up at 1.4 m height above the planting beds were adjusted for the SLI treatments: no supplemental lighting (control), photosynthetically active radiation (PAR) 30, 50, 70, and $90{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$ in 20 h daylength (17:00 to 22:00 and 02:00 to 09:00). Shoot growth including shoot elongation, shoot weight, and flowering speed was promoted quantitatively as SLI increased. But the flower quality such as petal numbers, petal pigmentation, and biomass distribution to the petals was declined at PAR 90, even though the proper SLI for rose production was generally known in the range of PAR 90 to 120. In this experiment PAR 90 treatment made the surface of petals heated near $30^{\circ}C$ which was about $10^{\circ}C$ higher than the control group without supplemental lighting. The surface temperature of the petals was continuously rising because the distance to lamps from floral buds became increasingly short as the shoots grew in local greenhouse facilities. The heat stress by HPS lamps caused petal discoloration and over-consumption of assimilation products due to excessive respiration and water loss in petals. Thus, it is necessary to prevent heat injury by switching light intensity depending on shoot growth considering local greenhouse structure.
