Abstract:
We determined how vapor pressure deficit (VPD) affects aboveground water relations in flower stems of roses. Plants were cultivated on soil-less substrate in two greenhouse chambers with contrasting humidity. Maximum differences in VPD were 1.34kP. Sap flux per unit leaf area averaged across 10 flower stems increased with increasing VPD. Flower stems on plants in the high VPD chamber had, on average, 47.3% greater sap flux per unit leaf area than plants in the lower VPD chamber (2.68±0.12 vs. 1.82±0.11kg m -2day-1. Maximum sap flux per stem average across 10 flower stems was not influenced by VPD and VPD had no influence on sap flux of stems of similar diameter. Rose flower stems acclimate to high VPD by decreasing leaf area and increasing sap flux per unit leaf area.
