“…Although biotic and abiotic factors are known to affect the global quality of tomato fruits (Gratao et al, 2008;Horchani et al, 2010), little is known about their effects on the nutrient composition of fruits (Carvalho Bertoli et al, 2012;Moral et al, 1994). In this case, our result showed that Cd changed fruit nutrient composition, depending on elements and developing fruit stage.…”

“…Earlier reports hypothesized that increases in root mineral concentrations could be partially explained by Cd interference with nutrient uptake by affecting the permeability of plasma membranes, as by altering their specific transporters (Dong et al, 2006;Irfan et al, 2013;Sandalio et al, 2001). In the same way, it has been shown that Cd-induced morphological changes of the conducting xylem tissue may also contribute to limited translocation of nutrients from roots (Carvalho Bertoli et al, 2012;Vollenweider et al, 2006). An inhibition of micro-and macro-nutrient accumulations by Cd in young tomato plants has been previously reported (Boulila-Zoghlami et al, 2006).…”

“…This raw material comes almost exclusively from the phloem's sap and so probably contributes to the fruit Cd content (Carvalho Bertoli et al, 2012). Through sampling of tomato at different fruit stage development, it was seen that the majority of fruit pericap Cd was accumulated during the last period of fruit development (RR).…”

“…However, few investigations have been done on the effect of chronic-Cd-stress on plants producing fruit (Carvalho Bertoli et al, 2012). Since fruits are sink organs that import mineral and photo-assimilates from roots and leaves, their growth and development may be impacted by Cd stress as well (Carvalho Bertoli et al, 2012;Gratao et al, 2012;Moral et al, 1994).…”

“…Mineral nutrition disturbances arise from deleterious Cd effects on the metabolism of essential elements, including calcium (Ca), magnesium (Mg), potassium (K), iron (Fe), zinc (Zn), manganese (Mn) and copper (Cu) (Carvalho Bertoli et al, 2012). In crop plants, Cd could interfere synergistically or antagonistically with nutrient uptake Clemens, 2006;Wu et al, 2007).…”

a b s t r a c t Edited by RA Street Keywords: Cadmium Mineral elements Solanum lycopersicum Seed FruitIn young tomato plants, modifications in mineral composition by short-term cadmium (Cd) treatments have been extensively examined. However, long-term Cd treatments have been fewly investigated, and little information about Cd-stress in fruiting plants is available. In the present work, we examined the changes in mineral nutrients of roots, stems, leaves, flowers, seeds and fruit pericarp of tomato plants submitted to a long-term Cd stress. After a 90-day culture period in hydroponic contaminated environment (0, 20 and 100 μM CdCl 2 ), fruit production was affected by increasing external Cd levels, with the absence of fruit set at 100 μM Cd. Meanwhile, Cd altered the plant mineral contents with an element-and organ-dependent response. At 20 μM, Cd triggered a significant increase in Ca content in roots, mature leaves, flowers and developing fruits. However, at 100 μM Cd, Ca content was reduced in shoots, and enhanced in roots. Cd stress reduced Zn and Cu contents in shoots and increased them in roots. High Cd level led to a significant decrease in K and Mg content in all plant organs. Furthermore, Fe concentration was reduced in roots, stems and leaves but increased in flowers, seeds and red ripe fruits. Our results suggest that tomato plants acclimatize during long-term exposure to 20 μM Cd, while 100 μM Cd results in drastic nutritional perturbations leading to fruit set abortion.

Variations in the nitrate assimilation, antioxidant system (superoxide dismutase, catalase, ascorbate peroxidase (SOD, CAT, and APX)), and lipid peroxidation (MDA) of Verbascum olympicum (Scrophulariaceae) exposed to cadmium (Cd) in Hoagland's nutrient medium were investigated. The accumulation of Cd and variations in the content of some trace elements (Cu, Mo, Mn, and Zn) and growth parameters as, e.g., the water content, biomass production and chlorophyll and soluble protein content were also studied. Cd treatment (0, 50, 100, and 250 µM Cd) was applied for seven days to eight weeks old seedlings in a growth chamber. Cd accumulated predominantly in the roots of V. olympicum, and the contents of Zn and Cu in the leaves and roots increased with the increasing Cd concentration. We found that increasing the Cd dosage inhibited the activity of nitrate assimilation enzymes and reduced the protein content, water content, and biomass production in the roots and leaves and the chlorophyll content in the leaves. Oxidative stress was confirmed by an increasing level of MDA in the seedlings. We concluded that this species has a powerful antioxidative defence system against Cd stress since SOD, CAT, and APX activities were induced.
