Abstract

Net CO2 exchange, dark respiration, light compensation points, and light acclimatization rates were determined for Brassaia actinophyIla Endl., Nephrolepis exaltata (L.) Schott ‘Bostoniensis’, and Epipremnum aureum (Linden & Andre) Bunt under 4 irradiation levels. These 3 species exhibited increased rates of net CO2 uptake and decreased rates of dark respiration at the lowest irradiances, indicating an increase in photosynthetic efficiency. They demonstrated a 1.4 to 5.0 fold reduction in light compensation points over a 7 week period of acclimatization. Brassaia actinophylla reached its minimum light compensation point in 5 weeks, Epipremnum aureum in 3 weeks, and Nephrolepsis exaltata ‘Bostoniensis’ never reached a fixed light compensation point.
