Abstrakt: This experiment was carried out to determine the percentage of internal connection between rootstock and scion in graft union with nondestructive and noninvasive MRI (Magnetic Resonance Imaging) method and to follow performance status according to internal connection ratios of the grafted rooted vines after planting to vineyard field. Research was established in a factorial randomized block design and carried out with cvs. Merlot and Syrah grafted onto 110 R rootstock and 4 different internal (MRI) connection levels in 3 replications. The percentages of grafted rooted vine internal determination by MRI by four sides (13.75%) in graft union were found to be very low than others at the pre-planting stage. An increase in the internal connection ratio in the majority of the grafted rooted vines was determined after the vegetative growth phase. Therefore, the internal connection ratios of the graft union of rooted vines of cvs. Merlot and Syrah varieties showed a tendency to increase during the second year of development. Again in both cultivars, loss rate of grafted rooted vines showed a decreasing tendency depending on increase of internal connection ratio of graft union. As a result, in case of decrease of MRI costs, it is thought that grafted rooted vine producers may have the opportunity to supply better quality seedlings to vine growers using MRI techniques.
