Abstract
The fruit of tomato is one of the highly consumed vegetables in the world, because of its increasing nutraceutical quality and positive effects on the health of the consumer. The objective of this research was to increase the content of antioxidants in tomato fruits, without significantly affecting yields, inducing abiotic stress in grafted and ungrafted tomato plants, subjecting to four different concentrations of salt (NaCl). The use of grafts increased the lycopene content and the activity of the enzyme ascorbate peroxidase (APx). The concentrations of 50, 75 and 100 mM de NaCl increased the content of vitamina C and the activity of superoxide dismutase (SOD) and APx. However, they reduced the lycopene content and the yields of the culture. The fruits obtained of the grafted plants subjected to 100 mM NaCl showed the highest amount of total phenols. The saline-free treatments had higher lycopene content, while the activity of SOD was increased with the graft and 100 mM NaCl. The maximum yields were obtained in grafted plants without salt stress.
