CULTURE METHOD FOR LONG-DAY PLANT AND FACILITY THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a culture method for long-day plants that is effective when far infrared in the range of the absorption wavelength of phytochrome A of a long-day plant is used and provide a cultivation facility suitable for long-day plants. SOLUTION: This culture method for long-day plant is provided with a step where far infrared light of which main emission wavelength is in the range from 700 to 800 nm, with a photon flux density of≥0.04μmol m-2s-1is continuously irradiated to long-day plants at an ambient temperature while the time when sunshine is not radiated. Further, the step where the plant is radiated with white light in the period of the time when the sun light is irradiated may be added to the step. COPYRIGHT: (C)2005,JPO&NCIPI
