Abstract: In a field experiment with grapevine (Vitis vinifera‘Red Globe’ / V. vulpina‘Beta’) , the selenium absorption, distribution and accumulation in grapevine organs and the effect on fruit qualities were studied. The results indicated that the orders of selenium distributionswere roots > leaves > shoots > stems > berries, an initial Se concentration in control was only 01009 mg·kg- 1DM in berries. After treatment with 0.5,1.0, 115 kg·hm^{- 2} Na₂SeO₃ , Se concentration in analyzed parts was mostly corresponded with increased Se
doses and significant increaseswere noticed. The excess of absorbed Se redistributed in plants and the orders of selenium distribution were leaves > roots > shoots > berries > stems. Se concentration in berries were 01062
mg·kg- 1DM in treatmentwith 1.5 kg·hm^{- 2} Na₂SeO₃. Se concentration in berrieswas almost the same at all phonological stageswhen Se content in single berry rose steadily and reached the highest in 90 days after flowering, but dropped with the fruit ripening. TSS increased significantly with the Se fertilization and there were no significant changes in mean fruit fresh mass, mean fruit drymass and TA.
