| Popis: | Mestrado Vinifera EuroMaster - Instituto Superior de Agronomia The characteristics of the berries and the seeds of two Sicilian cultivars compared to an international variety have been studied to gain a better understanding of some aspects concerning the reproductive process and fruit set in grapevine. Particularly, the empty-seededness phenomenon and its impact have been investigated by performing some viticultural practices in a randomized complete block in a wine grape vineyard located in the North-West Sicily, South Italy. This phenomenon led to empty seeds due to the embryo that aborts later becoming very small and endosperm that shrivel and degenerate, leaving them more or less hollow. It was evaluated how the performed treatments may affect these aspects evaluating their impact on the vegetative growth and productive activity. The leaf removal appeared suitable to prevent empty-seededness phenomenon decreasing floater seeds number in cultivars Grillo and Merlot, whereas in cv Nero D’Avola the tipping treatment was particularly relevant reducing the floater seed percentage |
