| This study was aimed to assess the effects of microclimate factors on lettuce chlorophyll fluorescent responses and to develop an environment control system for plant growth by adopting a simple genetic algorithm. The photosynthetic responses measurements were repeated by changing one factor among six climatic factors at a time. The maximum Fv'/Fm' resulted when the ambient temperature was $21^{circ}C,;CO_2$ concentration range of 1,200 to 1,400 ppm, relative humidity of $68%$, air current speed of $1.4m{cdot}s^{-1}$, and the temperature of nutrient solution of $20^{circ}C$. In PPF greater than $140{mu}mol{cdot}m^{-2}{cdot}s^{-1}$, Fv'/Fm' values were decreased. To estimate the effects of combined microclimate factors on plant growth, a photosynthesis efficiency model was developed using principle component analysis for six microclimate factors. Predicted Fv'/Fm' values showed a good agreement to measured ones with an average error of $2.5%$. In this study, a simple genetic algorithm was applied to the photosynthesis efficiency model for optimal environmental condition for lettuce growth. Air emperature of $22^{circ}C$, root zone temperature of $19^{circ}C,;CO_2$ concentration of 1,400 ppm, air current speed of $1.0m{cdot}s^{-1}$, PPF of $430{mu}mol{cdot}m^{-2}{cdot}s^{-1}$, and relative humidity of $65%$ were obtained. It is feasible to control plant environment optimally in response to microclimate changes by using photosynthesis efficiency model combined with genetic algorithm. |
