Irradiance, Temperature, and carbon dioxde enrichment affect photosynthesis in Phalaenopsis hybrids

Irradiance, Temperature, and carbon dioxde enrichment affect photosynthesis in Phalaenopsis hybrids

Hortscience 33(7): 1183-1185

The short-term effects of photosynthetic photon flux (PPF), day/night temperatures and CO2 concentration on CO2 exchange were determined for two Phalaenopsis hybrids. At 20degreeC, the saturating PPF for photosynthesis was 180 mumol cntdot m-2 s-1. At this PPF and ambient CO2 level (380 muL cntdot L-1), a day/night temperature of 20/15degreeC resulted in the largest daily CO2 uptake. Higher night temperatures probably increased the respiration rate and lowered daily CO2 uptake in comparison with 20/15degreeC. An increase in the CO2 concentration from 380 to 950 muL cntdot L-1 increased daily CO2 uptake by 82%.
