Geraniol is a monoterpene with a rose trait. This study aims to know the accumulation patterns of geraniol and its glycoside， and the other is to know the contribution of geraniol to the aroma of black tea. The result showed that the CSS (C.sinensis var. sinensis) cultivars possess a higher content of geranyl primeveroside than that in the CSA (C.sinensis var. assamica) cultivars. The amount of geranyl primeveroside in tea young leaf was highest among all tissues of the tea plant， while tea roots had the lowest accumulation of geranyl primeveroside. The fresh leaves of the tea plant in March had a higher accumulation of geraniol compared to those in other months. Furthermore， the results showed that the odor activity value of geraniol in six black tea infusions ranged from 3.93 to 28.38， strongly supporting the potential contribution of geraniol to the aroma of black tea samples. The strong coregulation was obtained between the expression of seven terpene synthase candidate genes and the accumulation of geranyl primeveroside. This work gives insight into the accumulation patterns of geraniol and its primeveroside and promote the research about the biosynthesis and regulation mechanism of geraniol in tea plant.
