Item Chemical diversity in coffee species of genebank of Instituto Agronômico do Estado de São Paulo(Crop Breeding and Applied Biotechnology, 2005-09-20) Aguiar, Adriano Tosoni da Eira; Fazuoli, Luiz Carlos; Salva, Terezinha de Jesus Garcia; Favarin, José LaércioThe objective of this work was to group different coffee species present in the genebank of the Instituto Agronômico by using some chemical variables. A total of thirty-nine plants belonging to seven species were analyzed for chemical seed components (soluble solids, lipids, trigonelline, chlorogenic acids and caffeine). The results evidenced that species could be grouped by lipids, chlorogenic acid, trigonelline and caffeine. The existence of great variation among and within species ranging from 24.12 to 30.65% for soluble solids; 8.68 to 17.49% for lipids; 0.32 to 2.15% for trigonelline; 2.91 to 6.38% for chlorogenic acid and 0.80 to 2.50% for caffeine was also observed, indicating the possibility to select plants of interest for the improvement of cultivated coffee species.
