| Research Abstract |
The physio-ecological significance of night temperature and its management in agriculture under the climate change was examined, and new methods for the night temperature management were proposed from the view point of sustainability and profitability. Effects of the night temperature on root absorptive function of vegetables and on translocation into fruits were analyzed quantitatively through their dependences on respiration. Furthermore, for the frost protection of tea, the leaf heat balance and the relationship of the frost tolerance temperature of tea leaves with the experienced night temperature and the concentrations of compatible solutes for frost tolerance was analyzed. From these results, an energy-saving night temperature management based on the translocation into fruits, an energy-saving local temperature management applying the constant soil temperature layer and an effective frost protection method were proposed.
