Induction of abiotic stress in tomato plants has been proposed as a mechanism for improving the nutritional quality of fruits. However, the occurrence of biotic stress can interfere with normal abiotic stress responses. In this study, the combined effect of water stress and infection with plant-parasitic nematodes on the nutritional, quality of tomato was investigated. Plants were exposed to one or both stresses, and the levels of phenolic compounds, carotenoids, and sugar's in fruits were analyzed as well as physiological responses. Levels of carotenoids lycopene and beta-carotene were lower . in water-stressed tomatoes but exhibited a different response pattern under combined stress. Nematode stress, was associated with increased flavonoid, levels, albeit with reduced yields, while chlorogenic acid was increased by nematodes, water stress and the combined stress. Sugar levels were higher only in tomatoes exposed to both stresses. These results emphasize the importance of studying plant stress factors in combination.
