Abstract:
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%).
