Outline of Final Research Achievements

The variety of flowering-cherries show various inflorescence architectures, which is one of the important traits affecting their ornamental quality. The size and structure of each inflorescence of 140 flowering-cherry cultivars were investigated at full-bloom stage. The inflorescence architecture diverged widely from corymb to umbel. The inflorescence size of each cultivar was related to the blooming date of each. The first step of inflorescence development was observed at the floral differentiation stage when flower primordia were initiated in the bud. The expression of some of FT/TFL1/CEN homologous genes were detected in inflorescence tissues, however the relationship between these gene expression and morphological variation couldn't be elucidated.
