| Outline of Final Research Achievements |
Effects of chilling accumulation and growth temperature on bud burst and flowering were clarified in the new low-chill cultivars ‘KU-PP1’ and ‘KU-PP2’ bred at Kagawa University. In addition, appropriate temperatures for tree growth at each growing stage were revealed by the cultivation experiments with growth chambers and the analyses of correlation between growth rate and temperature under natural conditions. Forcing culture with lower heating temperatures based on these researches was conducted, resulting in early harvesting with low energy. Furthermore, forcing with minimum heating preventing frost damage enable early harvest to some extent.
