Using of grafted plants provides a stability and tolerance against biotic and abiotic stress factors in tomato cultivation and increases yield and quality that depend on vigour of rootstocks. This study was conducted to determine the effects of different rootstocks on yield, quality and nutrient contents of grafted tomatoes in soilless culture. In the experiment, cv. Yankı F1 and cv. Esin Fı were used as plant material. Groundforce, Spirit F1, ES30501, ES30502, ES30503, body, Beaufort, Titron, 8411, R801 and K-8 were used as a rootstock. Nongrafted and selfgrafted plantswere used as control treatments. Marketable yield was obtained increasing rate by13.85 to 32.73% according to nongrafted and selfgrafted plants. Vitamin C, water soluble dry matter and titratable acidity were not affected significantly by rootstocks. Similarly, use of grafted plants did not affect the nutrient content of tomato fruits significantly.
Key words: Tomato, rootstocks, yield, nutrient content, quality, soilless culture, grafting.
