“…Ascorbate concentration in tomato fruit was also found to be reduced under high salinity (D'Amico et al, 2003), heat (Massot et al, 2013) and light stress conditions (Ioannidi et al, 2009;, all conditions favorable for BER appearance (Olle and Bender, 2009). Interestingly, fruit calcium concentration, the major known factor in BER initiation, has also been proposed to be positively correlated with ascorbate levels in tomato fruit (Premuzic et al, 1998) and the conditions favorable to BER, like salinity, drought and heat stress, were also found to increase ROS levels in tomato fruit (Leyva et al, 2013;Murshed et al, 2013Murshed et al, , 2014. Taking all these facts into account, there seems to be a connection between conditions that lower ascorbate concentrations and increase ROS levels to the susceptibility toward BER in tomatoes.…”

Calcium is widely accepted as the main factor responsible for blossom-end rot (BER) appearance in tomato (Solanum lycopersicum L.) fruit. However, reactive oxygen species (ROS), which can damage plant tissues have also been proposed to initiate BER appearance in tomatoes and other fruit-bearing vegetables. Ascorbate, the major antioxidant in tomato fruit, is generally lower during green fruit development, which corresponds to the stage of BER appearance. Accordingly, one hypothesis is that tomato cultivars with a lower susceptibility to BER under salt stress have higher ascorbate contents and thus better control of ROS levels. In this study, to clarify the relationship between BER incidence and oxidative stress, two BER resistant cultivars, 'Managua RZ' and 'House Momotaro' and one BER-susceptible cultivar 'Reiyoh', were cultivated under salinity or standard nutrient solution (control) conditions. Calcium, potassium, magnesium, total hydro-soluble antioxidants, and ascorbate concentrations were measured in the distal pericarp 1 to 2 days prior to symptom appearance and during symptom appearance in healthy and affected fruits. When salt stress was applied, only BER-resistant cultivars showed a significant increase in ascorbate contents prior to BER appearance as compared with their levels under the control condition. In contrast, pre-BER Ca concentrations. A similar tendency was also observed in apple "bitter pit". The ability to increase the fruit antioxidant capacity and maintain mineral balance under salt stress conditions may explain the resistance to BER development in highly resistant cultivars, probably by the avoidance of oxidative-induced cell necrosis and stabilization of the cell membranes, respectively.

“…Reduced water availability immediately affects cellular water status, solute transport, photosynthesis and transpiration (Murshed et al, 2013). Drought induces higher leakage of electrons toward O 2 during photosynthesis and respiration; this generates cellular oxidative stress, which enhances the production of reactive oxygen species (ROS) (Sánchez-Rodríguez et al, 2012).…”

Drought is a severe abiotic stress that affects global crop production. A drought model was created for 'Toyonoka' Fragaria × ananassa, and the effects of drought stress on contents of proline, sugars, and antioxidant enzyme activities were investigated. Strawberry transplants with identical growth were chosen for the experiments and the randomized design included four replications (10 plants per block). The experimental sets differed in the moisture level of the culture medium relative to the range of moisture content as follows: control, 70-85%; mild drought stress, 50-60%; moderate drought stress, 40-50%; and severe drought stress, 30-40%. Drought stress was imposed by limiting irrigation. Plants were sampled and physiological parameters were measured on 0, 2, 4, 6, 8, and 10 days after the commencement of drought stress. The water potential of strawberry leaves decreased in the plants under mild, moderate, and severe stress during the course of the water stress treatment and exhibited a significant difference from the control. Strawberry leaves subjected to drought stress had higher accumulation of proline, sugars, and malondialdehyde, and higher activities of superoxide dismutase, peroxidase, and catalase than leaves of control plants. Malondialdehyde levels increased in parallel with the severity and duration of drought stress. By contrast, antioxidant enzyme activity displayed dynamic responses to drought stress, first increasing and subsequently decreasing as the severity and duration of drought stress increased. These results suggest that strawberry plants respond to drought stress by altering the activities of antioxidant enzymes and the levels of osmotically active metabolites. These biochemical response changes may confer adaptation to drought stress and improve the capacity of plants to withstand water-deficit conditions.

“…The oxidation level in the pulp was not influenced by the notirrigated conditions in fruits at harvest for the early harvest stages (H1 and H2), but a significant difference was observed at the last harvest stage or after ripening, R1-R3, where irrigated fruits had 50% less H 2 O 2 than non-irrigated fruits These changes indicated that limited water supply induced oxidative stress, like in tomato (Murshed et al, 2013). The high contents in H 2 O 2 in ripe fruits from non-irrigated trees can also be related in part to the significantly high respiration rates measured in these fruits since these ROS compounds are produced by an increase in mitochondrial activity (Tian et al, 2013).…”

“…Other signals could also be implicated in ROS production such as ethylene, which is actively implicated in climacteric fruit ripening (Ebel et al, 1993). The increase in the content of reactive oxygen species in conditions of low water supply has been already shown by increasing the water stress intensity of tomato, another climacteric fruit (Murshed et al, 2013). However, MDA content did not present any difference between treatments, suggesting that if oxidation could induce membrane destruction, there is no direct correlation between MDA and H 2 O 2 contents in mango pulp.…”

The effects of a reduction in water supply during fruit development and postharvest fruit ripening on the oxidative status and the antioxidant defense system were studied in the mango fruit (Mangifera indica L.) cv. Cogshall. Changes in non-enzymatic (ascorbate) and enzymatic (SOD, CAT, APX, MDHAR, DHAR and GR) antioxidants, as well as oxidative parameters (H2O2 and MDA) and major carotenoids, were measured in unripe and ripe fruits from well-irrigated and non-irrigated trees. Under non-limiting water supply conditions, ripening induced oxidation as a result of the production of ROS and decreased ascorbate content. Antioxidant enzymatic systems were activated to protect fruit tissues and to regenerate the ascorbate pool. The carotenoid pool, mainly represented by β-carotene and esterified violaxanthine isomers, accumulated naturally during mango ripening. The suppression of irrigation decreased fruit size and induced accumulation of ABA and of its storage form, ABA-GE, in fruit pulp from the earliest harvest. It also increased oxidation, which was observable by the high levels of ascorbate measured at the early stages at harvest, and by the delay in the time it took to reach the pseudo constant carotene-to-xanthophyll ratio in ripe fruits. Nevertheless, differences between the irrigation treatments on the antioxidant system in ripe fruits were not significant, mainly because of the drastic changes in this system during ripening.
