Abstract

The relationship between the occurrence of cracking and morphological characteristics of 'Fujiminori' grape berries was studied in comparison with other tetraploid cultivars; 'Kyoho', 'Pione' and 'Takasumi'.<BR>The frequency of occurrence of berry cracking was markedly higher in 'Fujiminori' than in other cultivars. In 'Fujiminori' berries, the crackings were observed in the skin around the pedicel and stylar end. At the early ripening stage, crackings occurred predominantly around the pedicel.<BR>The reduction in the firmness of skin after veraison was much faster and greater in 'Fujiminori' than in other cultivars. In 'Fujiminori', several fractures occurred on the cork layer developed on the skin surface adjacent to the pedicel; then they penetrated into the flesh. Contrarily, in 'Pione', the fractures were healed by the development of the newly emerged cork tissue. The thickness of the cork layer was thinner in 'Fujiminori' than in the other cultivars. In 'Fujiminori', the depression of skin elongating longitudinally from pedicel to equator existed; subsequently the fleshy tissue beneath the depression collapsed.<BR>The skin around the stylar scar of 'Fujiminori' berry, exhibited small ring fractures one week after veraison; they gradually expanded until harvest. Only small fractures were observed in 'Pione' 6 weeks after veraison.
