Outline of Final Research Achievements

To study relationship between reproductive isolation and chemical characteristics of floral scent among closely related species including hybrids, I conducted floral scent analyses and field experiments using imitated flowers which contain scent chemicals of Akebia x pentaphylla. The imitated flower experiments tend to attract some small beetles which are not found in the parents species, A. quinata and A. trifoliata. In addition, I analyzed flora scents of Ipomoea alba, I. muricata. And I tried to produce their hybrid seeds between I. alba and I. muricata, but I could not. The scent profiles of I. alba and I. muricata were different each other and I. alba emitted larger amounts of volatile than I. muricata. I analyzed leaf volatiles (essential oils) of Magnolia virginiana to detect chemical marker to distingush northern and southern populations.
