This study was carried out to determine the effects of different rootstocks on graftsuccess, sapling development and graft compatibility/incompatibility of ‘Deveci’ and ‘Williams’ pearcultivars in Samsun ecological conditions between 2014 and 2016 years. Graft incompatibility wasattempted to be associated with morphological measurements in the graft union. Rootstock, cultivarand rootstockxcultivar interaction had a significant effect on the all examined parameters. In thestudy, graft take ratios were between 91.5-100.0%, graft sprout ratios were between 89.2-99.0% andsurvival ratios were between 83.7-99.0%. The graft sprout ratio was the highest in the OHxF333 andlowest was in the BA29 rootstock. The graft sprout and survival ratios were lower in quince rootstockthan in pear rootstocks. Rootstock diameters were higher in the OHxF333 and seedling rootstocksthan in the Fox11 and BA29 rootstocks. Graft union diameter and shoot diameter were lower in theFox11 than the other rootstocks. Shoot length was higher in the OHxF333 than the other rootstocks.Especially considering the graft success and the diameter measurements made in the graft union, ithas been found that some scion/stock combinations may show graft incompatibility. The‘Williams’/BA29 combination may be incompatible due to the lower survival ratio and diametervalues in the graft union than other combinations. Although graft success is sufficient, it should benoted that the ‘Williams’/Fox11, whose rootstock diameter and graft union diameter are lower thanthe others, may show graft incompatibility. ‘Deveci’ cultivar shows good compatibility with allrootstocks due to the higher graft success and sapling performance.
