   Most of horticultural produce (fruits, vegetables and ornamentals) easily deteriorate after harvest and lose their commercial value. We conduct  basic studies that focus on the mechanisms inducing the postharvest deterioration. We mainly work on the flower senescence in ornamental plants including cut flowers.<\/p>\n\n\n\n

1.Substances that improve vase-life of cut flowers<\/strong><\/h2>\n\n\n\n

   The plant hormone ethylene play a crucial role in inducing flower senescence in many ornamental plants. Carnation (Dianthus caryophyllus<\/em> L.) is one of the major cut flower items, and the flowers show ethylene-dependent senescence. We examine the effect of new substances as inhibitors of ethylene biosynthesis, and evaluate them as potential preservatives for the cut flowers.<\/p>\n<\/div>\n\n\n\n

2.Identification of genes responsible for flower longevity<\/strong><\/h2>\n\n\n\n

   Petal wilting is one of key events determining flower longevity in ornamental plants. To understand the molecular basis governing petal wilting, we isolate and analyze the genes associated with the process in carnation and balloon flower (Platycodongrandiflorus<\/em>(Jacq.) A. DC.), both of which show flower senescence with their petals (corollas) wilting severely.<\/p>\n<\/div>\n\n\n\n
