The relationships between temperature and light on vegetative growth of the foliage house plants Epipremnum aureum (Linden and Andre) Bund, and X Fatshedera lizei (Guillaum) were investigated in a controlled environment study during the exponential growth phase. Responses were examined under conditions with a constant day temperature (30°C) in combination with constant night, split-night or sliding night temperatures with means of either 15° or 20°C. Two PFDs of 150 and 320 μmol·s-1·m-2 were included in each temperature treatment. Growth parameters (including dry matter increase, shoot elongation rate and leaf production rate) were all influenced by species but not by each temperature profile within the same temperature integral (ie all growth responses were directly related to mean night temperature). Growth rates were highest under the high PFD conditions but dry weight accumulation per unit of PFD was markedly higher at low PFD than at high PFD. The optimum temperature for vegetative growth of Epipremnum aureum was higher than that for X Fatshedera lizei and Epipremnum aureum was particularly sensitive to temperatures below 10°C.
