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.

具有不同花香特征的近缘种间杂交的植物气味新颖性可能通过杂交推动物种形成。本研究采用气相色谱-质谱联用技术分析了强气味的奎纳塔（akbia quinata）、无气味的三叶橐吾（A. trifoliata）及其杂交品种五叶橐吾（A. pentaphylla）的花香特征。五谷草的气味特征介于亲本种之间。但也发现了一些从亲本中未检测到的化合物从五葡萄球菌中少量释放出来。本文还分析了禾草Acorus gramineus var. japonicus和禾草Acorus var. pusillus的花香。它们在质量上没有差别。但经核磁共振分析，主要挥发性成分为一种新化合物。
