| Outline of Final Research Achievements |
To establish the continuous production system for off-season blueberry, analysis of environmental factors to induce continuous fruits after blooming in fall was carried out and off-season production system was developed. Only SHB type such as 'Sharpblue' with low dormancy, evergreen and early flower bud formation habits showed the phenomenon of continuous flowering and fruiting after blooming in fall. Environmental conditions inducing continuous flowering and fruiting were temperatures (26°C) during light period and (12 ℃) during dark period, 8h photoperiod, light intensity (300-500μmol/m2/s) in closed room with artificial light. The blooming began in September when trees were placed in closed room from July and fruits could be harvested from December. Flowering and fruiting continued year-round and high quality fruits could be harvested with high SSC %, high anthocyanin and low acid %. It is possible to establish a new cultivation system for year-round, high yield blueberry.
