Abstract :
In order to investigate the mutual effect of root and scion on yield, yield components and some biochemical characteristics of four commercial varieties of tomato, a research was conducted in Fars province in 2016. In this regard, the combination of three rootstocks (Dashtestan, Doraheh, and Mond) and four grafts (Raad, Metin, Superchief, and Rockstone) were examined and after grafting, vegetative and reproductive traits and biochemical traits were measured. The results showed that different bases had a significant effect on the measured traits. According to the main effect of base, the highest percentage of success (up to 50%) was obtained using Dashestan base, while the lowest (40%) was observed in Mond base. On the other hand, there were significant interactions between root and scion in terms of parameters of days to flowering, plant height, average fruit weight, firmness, protein, lycopene, carotenoid, catalase and superoxide dismutase. Finally, it can be concluded that the best base and scion combinations were Raad and Superchif respectively on Dashtestan base, because in many parameters evaluated, these base and scion combinations were better than other combinations.Findings: The results showed that different bases had a significant effect on the measured traits. According to the main effect of base, the highest percentage of success (up to 50%) was obtained using Dashestan base, while the lowest (40%) was observed in Mond base.
