Research Abstract	Flora scent novelty in hybrid between closely related species which show different floral scent characteristics may drive speciation by hybridization. In this study I analyzed floral scent chracteristics of Akebia quinata (strong odor), A. trifoliata (scentless) and their hybrid, A. pentaphylla by GC-MS technique. The scent profile of A. pentaphylla was intermediate between the parents species. But, it was found that several compounds which were not detected from the parents were emitted from A. pentaphylla with small amount. I also analyzed floral scents of Acorus gramineus var. japonicus and A. gramineus var. pusillus. There was no difference between them in quality. But, the main volatile was a new compound which was determined by NMR analysis.
