Ameliorative effect of melatonin against storage chilling injury in pomegranate husk and arils through promoting the antioxidant system

Effect of exogenous melatonin in fruit postharvest, crosstalk with hormones, and defense mechanism for oxidative stress management

“…(2019a) observed the upregulation of genes PcACO and PcACS in MT‐treated pear fruits reduced ethylene and respiration rate, thus maintaining the fruit quality stored at room temperature. In relation to this, there have been many studies that conclude that MT treatment reduced the respiration and ethylene production rates in apples (Fan et al., 2022), pomegranates (Molla et al., 2022), cherries (Bal et al., 2022; Tijero et al., 2019), apricots (Medina‐Santamarina et al., 2021), oranges (Ma et al., 2021b), nectarines (Bal, 2021), mangos (Rastegar et al., 2020; Bhardwaj et al., 2022a) and bananas (Hu et al., 2017; Li et al., 2019a) (Tables 1 and 2). However, on the contrary, reports by Sun et al.…”

“…Electrolyte leakage is a hallmark of cell membrane damage during stress condition (Table 10). Exogenous MT decreases the electrolyte leakage in kiwifruit (Jiao et al., 2022), pomegranate (Molla et al., 2022), tomato (Azadshahraki et al., 2018), sweet cherry (Wang et al., 2019), bitter melon (Lin et al., 2020), and sapota (Mirshekari et al., 2020) and helps in preserving the fruit quality (Table 10).…”

“…CI can lead to symptoms like lenticel darkening, pitting, decay, uneven color development in mangos (Bhardwaj et al, 2022a(Bhardwaj et al, , 2022b(Bhardwaj et al, , 2022cSalazar-Salas et al, 2022), brownish pits in flavedo in oranges (Sun et al, 2019), mealiness and flesh browning in peaches (Cao et al, 2018), gel breakdown, flesh-reddening and internal browning in plums (Wang et al, 2016a;Xu et al, 2022), cell wall shrinkage in carrots (Lei et al, 2004), skin lignification in kiwifruit (Jiao et al, 2022), surface pitting in pomegranate (Molla et al, 2022), and tomatoes (Azadshahraki et al, 2018). To date, numerous studies have been conducted to ROS overproduction is a major cause associated with this injury (Gill and Tuteja, 2010;Zeng et al, 2016).…”

Exogenous MT decreases the electrolyte leakage in kiwifruit (Jiao et al, 2022), pomegranate (Molla et al, 2022) Mango "Langra," "Chaunsa," "Dashehari," "Gulab Jamun" 100 Higher 80% in "Langra," higher 2.28-fold in Chaunsa," higher 80% in "Dashehari," higher 40% in "Gulab Jamun" on day 28 bitter melon (Lin et al, 2020), and sapota (Mirshekari et al, 2020) and helps in preserving the fruit quality (Table 10).…”

A Synergistic Effect Based on the Combination of Melatonin with 1-Methylcyclopropene as a New Strategy to Increase Chilling Tolerance and General Quality in Zucchini Fruit

“…Strategies based into plant hormones or natural elicitors as γ-aminobutyric acid (GABA) [ 11 ], glycine betaine [ 12 ], polyamines [ 13 , 14 , 15 ] and methyl jasmonate [ 16 ] have also reduced CI impact in zucchini fruit. In this sense, melatonin has shown a positive effect delaying CI when applied as a postharvest treatment in different non-climacteric species as strawberry and pomegranate [ 17 , 18 ]. With respect to climacteric fruit, MT increased CI tolerance in peach [ 19 ] and tomato fruit [ 20 ] Also showing effectiveness against CI after preharvest treatments on apricot trees [ 21 ].…”
