DETERMINATION OF EFFICIENT LIGHT SOURCE FOR WHEAT PLANT BY USING DECISION TREES METHOD

摘要

Light is one of the important environmental factors for photosynthesis growth and development of plants.Plants' reactions to lights vary according to the light's wavelengths.Each color of light has different benefit for the biological and physical development of plants.In this study investigates the effect of light sources consisting of red and blue LEDs on photosynthesis of wheat plants.In the tests,the wheat plant was placed in a closed bowl to prevent environmental factors.The reaction of the plant exposed to different light sources were measured by sensors.The decision tree method was used to analyze 5040 temperature,humidity,carbon dioxide,oxygen and FAR values coming from the sensors and to achieve meaningful results.In the decision tree method,the gini index algorithm was preferred as the quality measure by which the division is calculated.The study has shown that the ideal light source of the wheat plant can change according to different environmental conditions.
