Preharvest application of methyl jasmonate (MeJA) in two plum cultivars. 2. Improvement of fruit quality and antioxidant systems during postharvest storage

Chitosan Coating: A Postharvest Treatment to Delay Oxidative Stress in Loquat Fruits during Cold Storage

“…The effect of chitosan coating on SOD activity is comparable to 1-MCP or methyl-jasmonate postharvest treatment on loquat fruits and on other fruit crops, such as peach, plum, pear and sweet cherry [24,25].…”

Methyl jasmonate delays postharvest ripening and senescence in the non-climacteric eggplant ( Solanum melongena L.) fruit

“…Zapata et al (2014) found that the effect of MeJA on ethylene production depended on MeJA concentration, fruit species, and even the cultivar within a species. In the current study, ethylene production change is consistent with a previous report where low ethylene production was observed in plums that received a preharvest MeJA treatment (Zapata et al, 2014). MeJA affects ethylene production by stimulation or inhibition of genes of ethylene biosynthesis.…”

“…(Peña-Cortés et al, 2005;Sayyari et al, 2011). Treatment of fruit with MeJA has been reported to improve fruit quality and stimulate host antioxidant systems during postharvest storage in plum, tomato, and red raspberry (Flores and Castillo, 2014;Zapata et al, 2014;Zhu and Tian, 2012). Application of MeJA also enhanced the resistance of papaya, loquat, and tomato fruit to Alternaria alternata, Colletotrichum acutatum and Botrytis cinerea, respectively (Cao et al, 2008;González-Aguilar et al, 2003;Yu et al, 2009).…”

Methyl salicylate treatments of sweet cherry trees increase antioxidant systems in fruit at harvest and during storage

“…The homogenate was centrifuged at 15,000 Â g for 30 min at 4 C and the supernatant used for enzyme assay. POD was determined as previously reported (Zapata et al, 2014), in a reaction mixture containing 50 mM phosphate buffer pH = 7.0, 12 mM H 2 O 2 , 14 mM guaiacol and 100 mL of enzymatic extract in a total volume of 3 mL.…”
