Abstract
Whole-plant photosynthetic rate of rose (cv.
Kardinal) was measured with an open system consisting of a computer-controlled data acquisition system and an infrared gas analyzer (IRGA). The system was used to monitor diurnal patterns of whole-plant gas exchange in response to environmental variables and a model to simulate this was constructed.
A model for leaf photosynthesis was calibrated and scaled up to the whole-plant level.
The simulated whole-plant photosynthesis compared well with the observed data.
The model can be used for identifying the impacts of varying environmental factors on whole-plant or canopy photosynthesis of roses in the greenhouse.
