Abstract
The pot plant nursery is described as a hierarchic system where the nursery with its yearly production is on the first level, the crop is on the next level, and the phases of development are on the third level.
The need of prediction models of the relationship between rate of development and factors in the environment (level 3) is stressed.
Such models would make it easier to target a date of sale with a higher precision than when using traditional blueprints.
Mechanistic models of how germination rate, rate of leaf development, rate of vernalization and floral development were affected by daily mean temperature, daily light integral and daylength is described for Senecio x hybridus Hyl.
The models were calibrated and tested against experimental data.
Approximately 90% of the variations in the experiments could be explained by the models.
The usage of the models for predictions at levels 2 and 3 in a computerized control of pot plant production is discussed.
