摘要

We investigated the effects of supplemental lighting, applied during the 60- day phase of flower induction, on growth and flowering of Phalaenopsis 'Premium', grown in pot. The experiment was carried out in Naples (40°51' N, 14°22' E), in an heated glasshouse. Plants were submitted to two lighting regimes, natural lighting and supplemental lighting. Supplemental lighting was performed by using High Pressure Sodium lamps, to provide an additional photosynthetic photon flux density (PPFD) of 150 μmol m~(-2) s~(-1), at the canopy level. The effects of treatments were studied in terms of plant growth, flowering time and flower stem production and characteristics. Supplemental lighting slightly anticipated flowering compared to natural lighting (144 vs. 150 days from the beginning of treatment) and positively influenced plant architecture, promoting the emission of the second flower stem and the flower stem branching.
