Effect of different rootstock on plant growth yield and fruit quality of tomato

This study was carried out in Ayer company in 2017. In this study, the effects of different rootstock on plant growth, fruit quality and yield of beef (large size) Ayer 38 Fı tomato were studied. Beaufort Fı (Antalya Tarım), Kingkong Fı (RijkZwaan), Hamarat Fı (Multi Tarım), Arazi Fı (Sygenta), Spirit Fı (Nunhems) were used as rootstock, Ayer 38 Fı was used as scion. As the control non-grafted and also self grafted plants (Ayer38Fı /Ayer38Fı) were tested in the experiments. According to result, ıt was observed that rootstock diameter ranged 14.5 mm-19.8 mm, early yield 5.93-8.89 kg/m2, the number of fruit per plant ranged from 21.5-54.5. The effects of scion/rootstock combination on total yield were significant and Ayer 38 Fı / Hamarat grafting combination resulted in higer yield than the other grafting combinations. Scion diameter, fruit fresh elasticity, internode length, number of leaf, plant high, EC and pH value of juice, titratable acidity, soluble dry matter content (sckm), fruit height, fruit diameter were not affected by the use of rootstock. Rootstock diameter, early yield, total yield, fruit weight, total fruit number were increased because of using rootstock. At the end of this study, ıt can be said that a favorable effect on yield and fruit quality of Ayer 38 Fı tomato variety can be achieved with proper rootstock selection and harmony between rootstock and scion is important in the grafted plant. Further research is needed to select the appropriate rootstock scion type.
