Senescent peel spotting, a physiol. disorder, develops during the latter stage of ripening which coincides with the best eating quality of ‘Sucrier’ banana fruit. It is a major constraint for banana growers and traders. The aims of this study were to evaluate the regulatory roles of Me salicylate (MeSA) on the senescent spotting and the activity of antioxidative ascorbate glutathione (ASA-GSH) cycle in ‘Sucrier’ banana during storage. ‘Sucrier’ bananas (ripening stage 3-4) were immersed in 0 (control) and 2 mM MeSA for 30 min, then air dried and stored at 25 ± 1°C for 6 d. After treatment, peel spotting, reactive oxygen species (ROS) production (hydrogen peroxide and hydroxyl radical contents), oxidative membrane damage (malondialdehyde and protein carbonyl contents and electrolyte leakage), enzymic and non-enzymic components of ASA-GSH cycle were determined It was shown that the symptoms of peel spotting in the control group was observed on day 2 and the severity increased continuously throughout storage. The occurrence of peel spotting coincided with the marked increase in the ROS production and oxidative membrane damage. The activities of ASA-GSH cycle including ascorbate peroxidase, dehydroascorbate reductase, monodehydroascorbate reductase and glutathione reductase activities as well as ascorbate (ASA) and reduced glutathione (GSH) contents declined with an increase in the severity of peel spotting. However, MeSA treatment caused an overall increase in the activities of enzymic and non-enzymic antioxidants as well as ASA/dehydroascorbate and GSH/oxidized glutathione ratios for up to 5-6 d of storage. The increased activity of ASA-GSH cycle was also associated with the decreases in ROS levels, oxidative membrane damage and senescent spotting development, indicating that MeSA treatment could reduce senescent spotting of ‘Sucrier’ bananas during storage by enhancing the activity of ASA-GSH cycle leading to the induction of antioxidant defense system to overcome ROS production, oxidative damage and fruit senescence.Methyl Salicylate(cas: 119-36-8Electric Literature of C8H8O3) was used in this study.
Methyl Salicylate(cas: 119-36-8) is a natural herbivore-induced plant volatile. It is a naturally occurring product in trees, legumes, exotic plants, vegetables, berries, and the primary constituent of the oil of wintergreen.Methyl Salicylate is produced from salicylic acid.Electric Literature of C8H8O3
