The Effects of Different Rootstocks on the Graft Success and Stion Development of Some Pear Cultivars

Abstract

In modern pear growing, quince and pear clonal rootstocks are used instead of pear seedlings. This study aimed to evaluate the effect of different quince and pear rootstocks on the graft success and the stion (scion+rootstock) growth performance of some pear cultivars/genotypes. In the study, quince (Quince BA 29, Quince A and Quince MC), pear (OHxF 333, Fox 11, Farold 40) clones and pear seedlings were grafted in two standard (Deveci and Williams) and 11 local ('Bardak,' 'Dalkıran,' 'Eşek,' 'İstanbul,' 'Kara,' 'Karga,' 'Karpuz,' 'Kış,' 'Sarıkum,' 'Tefenc' and 'Yaz Ziraati') promising pear cultivars were used. Significant differences were observed in both rootstocks and varieties in terms of graft success and plant development in the study. The graft take, sprout and survival ratios were higher in pear rootstocks than in the quince rootstocks. While the highest graft survival ratio was observed in Fox 11, the lowest was in the BA 29 quince rootstock. The highest graft sprout and graft survival ratio were in 'Deveci,' the lowest in 'Williams,' 'Bardak' and 'Kış' varieties. While the highest shoot lengths and highest diameters were detected in the pear seedling, the lowest were in the MC rootstock. While the longest shoots were observed in 'Kara,' the thickest shoots were observed in 'Eşek' genotypes. As a result of this study, it was determined that the 13 pear cultivars/genotypes grafted on different rootstocks were sufficient in terms of graft success and stion growth performances and it was found that stion of sufficient quality could be grown in the field condition.

Performance of grafting loquats combined onto loquat and quince rootstocks on different dates

“…The significant difference between the grafting success percentages of the two rootstocks suggests that loquat rootstock is more favorable for grafting success compared to quince rootstock. Our results are in conformity with the results of [15] and [14], who observed that rootstocks and varieties have a very important effect on the graft take ratio in the pear. The data presented in figure (3) demonstrate the effect of grafting time on loquat and quince rootstocks at different periods.…”

“…After grafting, the parenchymatous callus cells will be formed and the cambium junction between the scion and rootstock will take place within 7-14 days [13]. The percent grafting success 56.67−100.0% in the pear was reported by [14]. Environmental conditions during grafting, especially air temperature in the first 15 days after grafting directly affects the grafting success.…”

Productivity and Fruit Quality of ‘FalstaffPBR’ Pear Variety Grafted on Different Rootstocks

“…In pear crops, as well as for other fruit crops, it is well known that different rootstocks may influence not only the vigor but also other physiological characteristics of the plant [30][31][32][33][34][35], which could be photosynthesis, mineral status, secondary metabolites accumulation, abiotic and biotic stress tolerance, and even grafting success [36]. Therefore, choosing the best rootstock for the scion is crucial for its optimal exploitation and the successful development of the cultivar [22].…”

“…Therefore, it is not possible to efficiently select a rootstock based only on its characteristics, since many other significant factors are involved. In order to be able to enhance the agronomical features of a plant, different rootstocks have to be tested in order to evaluate the graft success and plant growth response of pear cultivars/genotypes and to select the better performing rootstock [22,23]. In our trials, we selected four different rootstocks: three quince (C. oblonga) ('Quince C' (EMC), 'Quince H' (EMH), and 'BA29'), as well as 'Farold 40' among clonal Pyrus communis L. rootstocks.…”

Growth, Yield and Quality Performance of Pear (Pyrus communis L.) cv. ‘Santa Maria’ under High Density Planting

“…Sixteen million tons (69.2%) of the production was carried out by China, followed by Italy, America, Argentina, and Türkiye is the 5 th position with 545.569 tons pear production [19]. The production of 'Santa Maria', which is widely used in pear cultivation, is increasing year by year in Türkiye [49,63]. The positive properties of grafting pears on quince rootstocks are controlling the growth of trees, precocity, and increase in yield and fruit quality.…”
