Outline of Final Research Achievements

This study, using LEDs emitting light of different wavelengths, measured and evaluated the influences of wavelength, light irradiation time, and irradiation method on flowering properties and flower quality. Also a method of growth stimulation was clarified using LED light and a method to enhance flower color. To assess flowering plant morphogenesis, the author explains methods for detecting the plant state. A new signal enhancement method using a convolution function is also proposed to emphasize the induction curve of the chlorophyll fluorescence. Results show that this study developed a basic technology providing an automated plant cultivation method for high-quality flower production.
