- Intervention effect Higher PFD shortened miniature rose flowering time from about 50 to 35 days at TEMP1.
- Intervention effect Higher PFD shortened miniature rose flowering time from 50 to 25 days at TEMP2.
- Intervention effect Higher PFD shortened Kalanchoe flowering time by about 15 days in both temperature treatments.
- Intervention effect Rose flower number and plant dry weight increased up to 300–400 PFD.
- Intervention effect Kalanchoe flower stem fresh weight and plant dry weight increased up to 200–300 PFD at TEMP1.
- Observation Rose CER saturated near 300 PFD at 370 CO2.
- Observation Rose CER saturated at 400–500 PFD at 800 CO2.
- Observation Kalanchoe showed similar CER saturation patterns.
- Intervention effect Increasing CO2 raised Kalanchoe CER by 69%.
- Recommendation The authors recommend 15 to 20 mol·m-2·day-1, about 24°C and high CO2 for rapid, flower-rich rose production.
- Recommendation The authors give 10 to 15 mol·m-2·day-1, about 20°C and high CO2 for similar Kalanchoe results.
