Dinamika nakupljanja antocijana i ukupnih fenola u bobicama sorti Probus i Kaberne sovinjon tokom sazrevanja u uslovima Fruške Gore

The anthocyanin and total phenols concentrations of Vitis vinifera cv Probus (Serbian wine grape variety) and Cabernet Sauvignon, during ripening in Fruska Gora region, were investigated. Phenolic concentration was evaluated by spectrophotometric analysis. Probus had higher anthocyanins concentration in the skin and total phenols per berry. Cabernet Sauvignon did not show big enlargement in anthocyanins content during this period. Contrastingly, anthocyanins content in Probus berry skin was increasing until harvest. Small berries of cv. Probus had colored pulp. There was a decrease in the Cabernet Sauvignon berry weight near the harvest. Optimum moment to harvest Probus was 50 days after veraison. Overall, these two varieties showed differences in anthocyanins accumulation during ripening.Cilj rada bio je da se ispita dinamika nakupljanja antocijana i ukupnih fenola u bobicama sorti probus i kaberne sovinjon tokom sazrevanja. Praćen je sadržaj ovih jedinjenja od šarka do berbe, u vremenskom razmaku od 10 dana. Sorte su pokazale različitu dinamiku nakupljanja. Dobijeni rezultati pokazuju da sorta probus nakuplja više bojenih materija od kaberne sovinjona
