Comportarea la altoire a soiurilor de viță de vie Gelu și Paula

Table grapes present some specific biological properties that distinguish them from wine grapes. The high production potential, the production being influenced in particular by choosing the best combinations of scion - rootstock, knowing that rootstock can affect both production and quality, is very important. High and very high vigor of the vines requires the use of certain varieties of rootstock with the same vigor that can support high production potential. In this work, two new creations of grape vines obtained at SCDVV Iasi, respectively Gelu and Paula were studied, in terms of their behavior after grafting, compared to a reference variety, Aromat de Iaşi. The reaction to grafting and the behavior during nursery period emphasized that the two varieties had a good behavior, between 73 and 88% of grafted and forced vines presented circular callus and new shoots, lower values than the control variety (92%), and the STAS obtained vines had values between 44-47% at Gelu, 46-55% at Paula, also lower than control variety Aromat de Iași(49 - 54%)
