Abstract: In this paper，we collected 55 tea varieties as materials under 2 different natural environmental conditions，Anxi and Wuyishan in spring，summer and autumn. The study showed that the REE（rare earth element）content of different tea varieties（lines）significantly varies from different seasons and habitat conditions，it exists absorption of certain laws：REE content from 13 tea varieties in Anxi behaves spring is higher than summer and autumn，while it is higher in Anxi than Wuyishan from 10 tea varieties. This assay also screened high，medium and low three levels enrichment of REEs from 55 tea varieties，number of three enrichment levels each were 1 for high（> 5.0 mg · kg-1），40 for medium（2.0–5.0 mg · kg-1），14 for low（0.91 ~ 2.0 mg · kg-1），respectively. Thus providing reference for the next screening of anti-REE tea cultivars and gives a reference for the production of planting material when picking and processing tea fresh leaves.
