Expression of expansin gene, MiExpA1, and activity of galactosidase and polygalacturonase in mango fruit as affected by oxalic acid during storage at room temperature

Effect of exogenous application of salicylic acid and oxalic acid on post harvest shelf-life of tomato (Solanum lycopersicon L.)

“…Pusa Gaurav showed maximum shelf life of 17 days in control and 21.66 days with 3 mM OA treatments, while Pusa Rohini showed 15 days of shelf life in control and 19.0 days with 3 mM OA treatment, while other cultivars had shelf life of less than 15 days in control and less than 19 days in treated (Table 1). Our results are in consistent with previous work where application of OA prolonged the shelf life of mangoes (Zheng et al 2005(Zheng et al , 2007b(Zheng et al , 2012a, peach (Zheng et al 2007a), Jujube fruits (Wang et al 2009), plum (Wu et al 2011) by maintaining softening, antioxidant activity and membrane integrity.…”

“…In recent years, application of exogenous OA at non-toxic concentration to fruits has been shown to be effective in retarding the ripening and increasing the shelf life of fruits like mango (Zheng et al 2007b(Zheng et al , 2012aDing et al 2007), peach (Zheng et al 2007a), Jujube (Wang et al 2009), plum (Wu et al 2011), muskmelon (Jian-jun et al 2008, kiwi (Zhang et al 2006), reducing chilling injury of pomegranate (Sayyari et al 2010) as well as inhibiting browning of litchi (Zheng and Tian 2006).…”

Oxalic acid preharvest treatment increases antioxidant systems and improves plum quality at harvest and during postharvest storage

“…However, the effect of OA treatment on increasing phenolic and anthocyanin content in plum is reported for the first time in the present study and could be attributed to the activation of phenylalanine ammonia‐lyase (PAL) activity, the key enzyme in the phenylpropanoid pathway involved in phenolic biosynthesis. In fact, increases in PAL activity have recently been reported in mango and muskmelon fruits as a consequence or postharvest OA treatment.…”

“…Accordingly, postharvest OA treatment promoted accumulation of total phenolics in muskmelon, mango, pomegranate and sweet cherry fruit during storage, leading to fruit with higher antioxidant capacity. Moreover, the application of OA treatment to peach trees 15 days before harvest increased bioactive compounds, such as total phenolics and flavonoids, and antioxidant potential in peach fruit at harvest and during cold storage .…”

Postharvest biology and technology of pomegranate

“…Oxalic acid (OA), as a final metabolite product on plants, has many physiological functions, the main one being related to the induction of systemic resistance against diseases caused by fungi, bacteria and viruses, by increasing defense‐related enzyme activities and secondary metabolites such as phenolics . OA applied at three concentrations (2, 4 and 6 mmol L −1 ) by dipping of ‘Mollar de Elche’ pomegranate fruits significantly reduced CI symptoms, especially at 6 mmol L −1 concentration .…”
