چکیده
Polyploidization can provide changes in vital features such as growth, development, environmental stress tolerance plants. Colchicine is one of the most commonly used chemicals a polyploidization agent. In this study, 2-year-old ‘Ekşi Kara’, ‘Gök Üzüm’ and ‘Trakya İlkeren’ (2x, Vitis vinifera L.) saplings grown on their own roots were used. When enforced shoots reached about 15 cm length, colchicine applied (0, 2.5 g L-1, 5 7.5 L-1) 24 48 hours to lateral shoot tips. The effects treatments evaluated by tip viability, stoma size density, chloroplast counts, flow cytometry (FC) analysis, ‘Kyoho’ (4x) control. maximum stomatal variations determined Ekşi Kara cultivar at L-1 24-h application. Based morphological differences, FC analysis was performed only Kara’ but, there no genomic duplication. Since differences not sufficient diagnosis polyploid grape cultivars, should be achieve confirmed results.

Glycosidic aroma compounds of some Portuguese grape cultivars
In order to evaluate the potential aroma of some Portuguese grapes, several glycosidically bound aroma compounds of ten grape varieties grown in Évora, Alentejo, Portugal, were released, identified and quantified using gas chromatography–mass spectrophotometry. White varieties were Arinto, Perrum, Rabo-de-Ovelha, Roupeiro and Antão Vaz. Red varieties were Trincadeira, Aragonez, Tinta Caiada, Mo...
