The study evaluated morphological (skin, pulp and seeds) and chemical indicators of grape berry. The total composition of flavonoids in grains, in the autochthonous vine cultivar Shesh I Bardhe, in three micro areas of Albania (Gjirokaster, Tirana, Durres) was carried out by the spectrophotometric method and was classified as 165.62; 66.36; 183.85 mg/L of gallic acid respectively for different ecoclimatic zones. The sugar content was 13.53 ºBrix per cv Sh. iBardhe, Gjirokastra; 17.5 ºBrix per cv Sh. iBardhe, Tirana and 11 ºBrix by cv Sh. I Bardhe, Sukth.
From the results obtained, it was noted that the effect of the climatic zones, influenced the content of total flavonoids as a result of the different ripening times of the fruit, significant changes were also observed in the morphological indicators of the grape (grain weight, coefficient of construction, weight of 100 grains, husk content, seed content, grain size (length / width), grain index, grain composition coefficient). There is a connection of morphological indicators with environmental factors in the vineyard, recognizing the requirements that the vine plant has four edaphological and climatic factors. It is also worth mentioning the agrotechnical services that are provided to the vineyards, especially fertilization or irrigation, but also the forms of maintenance or pruning, which are crucial factors in the quality indicators of production.
In our study we have only made a definition of physical-chemical quality indicators in three ecozones of Albania, but an in-depth analysis of agrotechnology and beyond should be practiced
