Outline of Final Research Achievements

One of the most useful feature of indoor farm using artificial lightings is that the crop can be grown uder modified light cycles. Therefore, the yield and quality of the crop can be improved by optimising the light cycles.This study was conducted aiming to optimize the light cycles in terms of the transport of photosynthates from leaves to fruits,and develop a system for monitoring the oscillating photosynthesis and photosynthate transport.The near infra-red spectrum method was applied to monitor sucrose concentration of photosynthesising leaves.In addition, the use of photoreceptor mutants thatexibit modified circadian rhythms for modifying the diurnal changes in photosynthate transport into fruits.
