“…Instead of rootstocks with vigor growth and development in today's modern pear cultivation, dwarf or semi-dwarf quince and pear clone rootstocks are used (Hancock and Lobos, 2008;Dondini and Sansavini, 2012;Hepaksoy, 2019). Pear clonal rootstocks show stronger development compared to quince clone rootstocks, so planting distances are wider (Ozcagiran et al, 2005;Sharma et al, 2009;da Silva et al, 2018). Although pears are grown on quince rootstocks with control the growth forces of trees (dwarfing), yield precocity, increase in fruit yield and quality, due to their negative aspects such as sensitivity to winter cold, chlorosis and fire blight in calcareous soils, weak anchorage to soil and poor graft compatibility (Pina and Errea, 2009) instead of Pyrodwarf, OHxF, Farold, Fox, BP and CTS series developed in different rootstock breeding programs and pear clone rootstocks from some different pear species have been used in recent years (Jackson, 2003;Hancock and Lobous, 2008;Dondini and Sansavini, 2012;da Silva et al, 2018).…”

“…New pear rootstocks were improved many years later in different breeding programs (da Silva et al, 2018;Hepaksoy, 2019). It is important for pear cultivation to investigate the effects of these new pear rootstocks on the growth and development forces of the cultivars grafted on rootstocks, as well as their resistance to biotic and abiotic stress conditions.…”

“…The effect of cultivars grafted on rootstocks on growth characteristics determines the growing ability of the cultivars. In this respect, to reveal how the rootstocks affect the morphological characteristics of the cultivars grafted on the rootstocks (Rahman et al, 2017;da Silva et al, 2018) is very important for the pear producer that will grow with these saplings.…”

This study was carried out to determine the effects of different pear and quince rootstocks on some branch and leaf properties of 'Deveci' and 'Williams' pear cultivars at Samsun ecological conditions in 2015-2016 years. The number of lateral branches (number plant-1), lateral branch length (cm) and diameter (mm) and branch angle (o) and petiole length (cm) and thickness (mm), leaf width and length (cm) and leaf area (cm 2 leaf-1) were examined in the study. Rootstock and cultivar and rootstock x cultivar interaction had significant effects on all examined branch and leaf traits. The 'Deveci' cultivar had generally got better lateral branch characteristics and higher leaf size than the 'Williams'. The highest lateral branch number was observed in the OHxF333 rootstock, while the highest lateral branch diameter was found in the seedlings rootstock. The BA29 rootstock had wider angled branches than the other rootstocks. Leaf area was the highest in OHxF333 rootstock and the lowest in BA29 rootstock. The highest number of lateral branch was determined in the 'Deveci'/Fox11 and the lowest was in the 'Williams'/Fox11 scion/rootstock combinations. The longest lateral branches were detected in the 'Deveci'/BA29 and the 'Deveci'/seedling. The highest leaf area was found in the 'Deveci'/BA29 and 'Williams'/seedling and the lowest was in the 'Williams'/BA29 scion/rootstock combination. As a result, in this study was determined that the cultivars grafted on different rootstocks affect their growth and development by affecting their vegetative growth and morphological traits.

“…In order to eliminate the negative effects of graft incompatibility in pear/quince grafting combinations, dwarf and semi-dwarf quince and pear clonal rootstocks such as BA29, Adams, Sydo, Pyrodwarf, OHxF, Farold, Fox, BP and CTS series in different rootstock breeding programs have been used in recent years (Jackson, 2003;Hancock and Lobous, 2008;Dondini and Sansavini, 2012;da Silva et al, 2018). It is important for pear cultivation to investigate the effects of these new pear rootstocks on the growth and development vigor of the cultivars grafted on them, as well as their resistance to biotic and abiotic stress conditions.…”

This study was carried out to determine the effects of different rootstocks on graft success, sapling development and graft compatibility/incompatibility of 'Deveci' and 'Williams' pear cultivars in Samsun ecological conditions between 2014 and 2016 years. Graft incompatibility was attempted to be associated with morphological measurements in the graft union. Rootstock, cultivar and rootstockxcultivar interaction had a significant effect on the all examined parameters. In the study, graft take ratios were between 91.5-100.0%, graft sprout ratios were between 89.2-99.0% and survival ratios were between 83.7-99.0%. The graft sprout ratio was the highest in the OHxF333 and lowest was in the BA29 rootstock. The graft sprout and survival ratios were lower in quince rootstock than in pear rootstocks. Rootstock diameters were higher in the OHxF333 and seedling rootstocks than in the Fox11 and BA29 rootstocks. Graft union diameter and shoot diameter were lower in the Fox11 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, it has 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 diameter values in the graft union than other combinations. Although graft success is sufficient, it should be noted that the 'Williams'/Fox11, whose rootstock diameter and graft union diameter are lower than the others, may show graft incompatibility. 'Deveci' cultivar shows good compatibility with all rootstocks due to the higher graft success and sapling performance.
