Outline of Final Research Achievements

In Japan,the harvesting period of blueberries grown under natural conditions is from June to September. From the attempts of off-season production and continuous harvesting of some cultivars of southern highbush blueberries (SHB), results showed that it was possible to produce off-season fruits in a controlled environment. Therefore SHB that was treated with high temperatures and long-day lengths in September flowered on terminal bud in October. Flower bud differentiation was stimulated by low temperatures and short-day lengths after terminal bud flowering. Therefore, it is possible to harvest fruits continuously from December to July by subsequent flowering from the mother branch. RNA-Seq revealed that several genes showing high homology with flowering-related genes of Arabidopsis expressed in the new leaves of blueberry under the cultivation conditions of continuous harvesting. This observation suggests that blueberry have several flowering pathways as is the case of Arabidopsis.
