Outline of Final Research Achievements

To discuss an optimization strategy of the rose plant architecture and the environment control, a growth simulation model of greenhouse rose vegetation was developed. Using the light-temperature-photosynthesis curve generated by measuring the photosynthetic and respiration rates under fluctuating environments, we constructed a system dynamics (SD) model which predicts daily carbon gain. In addition to this, the distribution ratios of photosynthates produced by the bending shoots to other organs were evaluated by 13CO2 feeding experiments.
From the results of the SD model validation, it was found that both photosynthesis during daytime and respiration during nighttime are over-estimated and that the error becomes larger in winter. The course of these prediction errors was discussed.
