Özet:

This research was carried out under nursery conditions, in 2016-2017 with the aim of determining the take the ratio of grafted vines and quality of grapevine saplings of Kabarcık and Hönüsü varieties grafted on American rootstocks (1103 Poulsen and 110-R). Grapevine ‘cv. ‘Kabarcık’ and ‘Hönüsü’ was grafted on two different rootstocks by omega grafting method. Paraffined grafted cuttings were stratified in kept in a water bath and then placed into climate room (23-25°C and 75-80% relative humidity) for 4 weeks. Grafted cuttings, having 75% callusing on graft union were planted in garden land, perlite, stream shaft and burnt farmyard manure (1:1:0.5:0.5) mixture and rooted under controlled conditions (25 and 27 °C, % 70-75 relative humidity and 16 h photoperiod) for six weeks. The rooted seedlings were transferred to the shading house by transferring them to external conditions. As a result of this study, the rootstocks had different effects in terms of callusing, rooting and sprouting ratios (%), callusing levels (0-4), rootstock thickness (cm), vaccination point thickness (mm) number of roots, root length (cm) the ratio of grafted cuttings having planting quality (%) and the ratio of grafted vines (%). Regarding the ratio of grafted vines, the best results were obtained from Kabarcık/1103 Poulsen (60.66%), the lowest ratio was determined in 110-R with 37.00%. The highest rooting rate was achieved in 1103 Poulsen rootstock with 68.50%. Under the conditions of the study area, the best variety quality of the grape varieties was determined to be in the grafted varieties on 1103 Poulsen rootstock.  .
