Linking field studies and molecular physiology
to understand fruit tree growth and fruit quality
Recent Research
１．Elucidation of the mechanisms controlling fruit tree growth
— Toward labor-saving pruning and canopy management —
Excessive or insufficient vegetative vigor in fruit trees negatively affects labor efficiency, yield, and fruit quality. Using grapevine as a model, we study the regulation of shoot growth, flowering, and fruit development, focusing on plant hormone functions.
２．Improving fruit quality under high-temperature conditions
Recent climate warming has caused fruit quality deterioration, such as poor coloration and sunburn. Focusing on grapevine and citrus, we investigate the mechanisms of quality loss under high-temperature conditions and develop stable production technologies suited to warm climates.
３ ．Genetic characterization and breeding utilization of fruit tree resources
We use genomic DNA information to characterize fruit tree genetic resources, including wild grapes and the cultivar “Kadai-Nou R-1,” and apply this knowledge to the development of improved cultivars for warm regions and winemaking.
