In order to study the impact of salt stress (0, 1.5, 3 and 6) ds.m-1 in nutrient’s solution on tomato plant (Solanum lycopersicum L. cv. memory) at different root zone temperature [low (20°C), medium (25°C) and high (30°C)], an experiment was carried at Department of Horticultural, Ferdowsi University of Mashhad, Islamic Republic of Iran. The result showed that low and high root zone heating decreased leaf area, total sugar and phenol content compared to root zone temperature 25°C (optimum), while main branches number, pH, E.C. and anthocyanin of fruit ,increased at high root zone temperature compared to low root zone temperature. Flavonoid increased under the root zone temperature of 20°C in comparison with temperatures 25 and 30°C, and stem diameter was not affected by root zone heating. Furthermore, salt stress at the level of 3 ds.m-1 increased stem diameter, total sugar, pH and EC of fruit, leaf area and phenol content, whereas salt stress at a high level (6 ds.m-1) increased flavonoid content. Besides, anthocyanin content decreased in control and salt stress at 6 ds.m-1 when compared to salt stress at 3 ds.m-1.

The effect of water deficit on concentrations of carotenoids was investigated in ripening tomatoes using HPLC-PDA. Fifteen different tomato cultivars were grown under three levels of water supply and unripe and fully-ripe fruits were harvested at different stages. Water deficit significantly affected several morphological and fruit yield-related parameters. In unripe tomato fruits, the relative concentrations of xanthophyll cycle carotenoids, e.g., violaxanthin and antheraxanthin, were significantly increased at the expense of ?-carotene upon limiting the water supply. In ripe fruits, nutritionally-relevant lycopene, ?-carotene and lutein levels were broadly independent of water deficit when considering all 15 cultivars, although significant variations were observed among fruits from different genotypes. Our study highlights the importance of careful genotype selection for the production of tomatoes rich in nutritionally-relevant compounds like lycopene and ?-carotene.
