Abstract: The present study focused on the relationship between changes of free and glycosidic(-)-α-terpineol concentrations and expression of a Vvter gene encoding(-)-α-terpineol synthase during development of grape(Vitis vinifera L.‘Cabernet Sauvignon’and‘Riesling’)berries by using technologies of GC-MS and real-time PCR. The results showed that in these two cultivars glycosidic(-)-α-terpineol concentrations varied little in the process of berry development. Free(-)-α-terpineol concentration gradually decreased with development of‘Cabernet Sauvignon’berries and showed decrease-increase- decrease variation trends with development of’Riesling’berries. In respect of a variety,the variation trend of total(-)-α-terpineol was in good agreement with that of transcript.

Key words: grape, berries, (-)-α-terpineol, (-)-α-terpineol synthase
