“…Positive correlations between accumulation of endogenous proline and improved cold tolerance have been found mostly in chilling-sensitive plants (Zhao et al 2009;Korkmaz et al 2009). Our data, which showed a definite increase in proline content of salicylic acid treated fruit along with amelioration of CI, confirm this finding.…”

Tomato fruit at the mature green stage were treated with salicylic acid at different concentration (0, 1 and 2 mM) and analyzed for chilling injury (CI), electrolyte leakage (EL), malondialdehyde (MDA) and proline contents and phospholipase D (PLD) and lipoxygenase (LOX) activities during cold storage. PLD and LOX activities were significantly reduced by salicylic acid treatment. Compared with the control fruit, salicylic acid treatment alleviated chilling injury, reduced electrolyte leakage, malondialdehyde content and increased proline content. Our result suggest that the reduce activity of PLD and LOX, by salicylic acid may be a chilling tolerance strategy in tomato fruit. Inhibition of PLD and LOX activity during low temperature storage could ameliorate chilling injury and oxidation damage and enhance membrane integrity in tomato fruit.

This experiment was conducted to evaluate the effects of drought stress on some quality traits of tomato, seven tomato lines were assessed in an experimental field at Ilam University in 2016. The layout was split plots according to randomized complete block design (RCBD) with 3 levels of drought stress including 100, 60% and 40% of field capacity with 3 replications. The genotypes were including King stone, Peto early, Bitstoik, LA1607, LA2656, LA2080 and LA1579. The effect of mild and severe drought stress on the activity of antioxidant enzymes, including peroxidase, catalase and ascorbate peroxidase were investigated. The statistical analysis showed that drought stress significantly affected all assessed traits under drought condition. CAT, chlorophyll content and RWC were reduced, but, APX, POX, Proline and MAD content as well as electrolyte leakage increased and the highest content was observed under severe drought stress (40%FC). The genotypes LA1607, LA2656, LA2080 and LA1579 identified as the most tolerant and King Stone, Peto early and Bitstoik were the most susceptible genotypes. Under severe drought stress, the highest RWC in LA2080, POX in LA1579, APX in LA1607, Chlorophyll a in LA2080, Chlorophyll b in Peto early, Chlorophyll T in Bitstoik and LA2080, EL in LA2080, MDA in Bitstoik and prolin in Petoearly were observed.

“…Some high-value vegetable crops of tropical or subtropical origin, such as the pepper plant (Capsicum annuum L.), are sensitive to cold temperatures. The optimum temperature for the growth of pepper ranges between 21° and 27°C, and growth is retarded below 12°C and above 30°C (Korkmaz et al, 2010). Chilling stress affects a multitude of physiological and biochemical processes, causing poor germination, slow growth, discoloration or yellowing, withering, necrotic lesions, and membrane disintegration.…”

ABSTRACT. To elucidate how physiological and biochemical mechanisms of chilling stress are regulated by abscisic acid (ABA) pretreatment, pepper variety (cv. 'P70') seedlings were pretreated with 0.57 mM ABA for 72 h and then subjected to chilling stress at 10°/6°C (day/night). Chilling stress caused severe necrotic lesions on the leaves and increased malondialdehyde and H 2 O 2 levels. Activities of monodehydroascorbate reductase (DHAR), dehydroascorbate reductase, glutathione reductase, guaiacol peroxidase, ascorbate peroxidase, ascorbate, and glutathione increased due to chilling stress during the 72 h, while superoxide dismutase and catalase activities decreased during 24 h, suggesting that chilling stress activates the AsA-GSH cycle under catalase deactivation in pepper leaves. ABA pretreatment induced significant increases in the above-mentioned enzyme activities and progressive decreases in ascorbate and glutathione levels. On the other hand, ABA-pretreated seedlings under chilling stress increased superoxide dismutase and guaiacol peroxidase activities and lowered concentrations of other antioxidants compared with untreated chilling-stressed plants. These seedlings showed concomitant decreases in foliage damage symptoms, and levels of malondialdehyde and H 2 O 2 . Induction of Mn-SOD and POD was observed in chilling-stressed plants treated with ABA. The expression of DHAR1 and DHAR2 was altered by chilling stress, but it was higher in the presence than in the absence of ABA at 24 h. Overall, the results indicate that exogenous application of ABA increases tolerance of plants to chilling-induced oxidative damage, mainly by enhancing superoxide dismutase and guaiacol peroxidase activities and related gene expression.
