Research Abstract

The aims of this project are to clarify the mechanism of petal growth during flower opening, and to control flower opening of cut roses in post-harvest conditions. I found that the Expansin and XTH play important roles for flower opening of cut roses by real-time PCR analysis and western blot analysis. And XG9 was analyzed as an inhibitor for XTH enzyme activity. XG9 promoted the flower opening of cut roses at high concentration, and in contrast, XG9 inhibited it at low concentration. Furthermore, it became clear that the petal of cut rose buds grew for only a few hours from the initiation of light period, and it hardly grew during the rest periods.
