Abstract: Samples of soils and tea leaves in both spring and autumn were collected from seven typical tea gardens in Jing County and the Anhui Provincial Tea Cultivar Breeding Garden,and contents of total selenium in the samples were determined in an attempt to investigate selenium partitioning between soil and tea,distribution of Se in tea organs and their relationship with the soils and tea cultivars.Results show that the average soil Se were （0.413±0.146） mg·kg^-1,higher than the average background value of China.Distribution of soil Se in the soil profile varies with soil depth,soil pH,and organic matter content.And the spring tea was medium in Se level(0.096⁰.216 mg·kg^-1),but higher than the autumn tea.Thus,Se content in tea is resulted from a common function of soil Se,tea harvesting season and tea cultivar.Production of green tea with high Se could,therefore, be achieved through breeding Se-accumulating cultivars,rationalizing Se fertilizer application,regulating soil pH,and timing of harvesting.
