“…One of them is to apply plant growth regulators before and after harvest. Aminoethoxyvinylglicine (AVG), polyamines (putrescine), 1-methylcyclopropene (1-MCP) and jasmonates (MeJA) are the most common growth regulators used for extending post-harvest storage life of horticultural crops (Jobling et al, 2003;Khan and Singh, 2010).…”

Background: Plum fruits constitute a good source of natural antioxidant substances. Particularly, plums contain large amounts of phenolic compounds and flavonoids having natural antioxidant activity which is effective in human diet. The aim of this study was to evaluate the effects of pre-harvest MeJA treatment on the fruit quality and bioactive compounds of three different Japanese plums under storage conditions. Materials and Methods: The effects of pre-harvest methyl jasmonate treatment (MeJA) on weight loss, color characteristics (L*, C* and h°), firmness, soluble solids content (SSC), titratable acidity (TA), total phenolics (TP) and total antioxidant activity (TAA) of 'Black Beauty', 'Black Amber' and 'Fortune' plum fruits during the cold storage (at 0±0.5 C and 90±5% RH) were investigated in this study. Results: MeJA did not have significant effects on the weight loss (%) of 'Black Amber' and 'Fortune' fruits, whereas it was effective in delaying the weight loss of 'Black Beauty' at the end of storage. The color characteristics of all plum cultivars were not significantly affected by MeJA at the end of storage. In all plum cultivars, the SSC increased, while TA significantly (P<0.05) decreased during storage. TP and TAA of 'Black Amber' and 'Fortune' fruits significantly increased during the cold storage. MeJA treatments increased fruit firmness, TP and TAA (according to FRAP) of 'Fortune' plums at the end of storage. Conclusion:The scientific results about the effects of pre-harvest MeJA treatments on the cold storage of Japanese plums may contribute significant helps to improve plum storage durations and quality characteristics.

“…Previously, AVG treatment has been found to inhibit ethylene production but not influence quality of peach and nectarine (Bergoli et al 2006) and apricot (Muñoz-Robredo et al 2012). The lack of effect of AVG treatment on postharvest storage quality of feijoa does contrast with other studies in which firmness (for example) was retained in apple (Drake et al 2006;Yildiz et al 2012), pear (Clayton et al 2000;D'Aquino et al 2010), plum (Jobling et al 2003), nectarine (Torrigiani et al 2004) and peach (Cetinbas et al 2012). Other quality properties that have been observed to be influenced by AVG include SSC (e.g.…”

“…Bregoli et al (2002) found that peaches treated 8 d before harvest by AVG inhibited ethylene production and increased soluble solids content (SSC). Jobling et al (2003) found that AVG treated plums allowed a delay in harvested timing, and resulted in retaining higher firmness and SSC in comparison with untreated fruit, suggesting that accumulation of soluble solids can take place when fruit are on trees for longer.…”

In a previous study, feijoa harvested earlier than 'touch-picked' maturity appeared visually acceptable after 6 weeks of storage but had low soluble solids content (SSC) and high titratable acidity (TA). Given that feijoa display climacteric-like behaviour, manipulation of ethylene physiology prior to harvest may have the potential to alter this outcome. Subsequently, the aim of this work was to investigate the impact of preharvest aminoethoxyvinylglycine (AVG) application on feijoa quality at harvest and during subsequent storage. The experiment comprised of three preharvest AVG treatments and two harvest occasions. AVG treatment dramatically reduced preharvest fruit drop. AVG treatment at 4 weeks before current commercial harvest timing was effective in delaying maturity. AVG treatment suppressed ethylene production rates during storage. However, AVG treatment did not alter quality (firmness, SSC, TA and flesh colour) after storage. This result adds to the evidence that postharvest ripening in feijoa may be regulated independent of ethylene despite the typical climacteric increase in ethylene observed. The results also confirmed that fruit harvested early were storable for 6 weeks without exhibiting internal browning, but having a high TA and low SSC that may affect their taste acceptability.

This research aimed to identify the possible effects of the moment of Aminoethoxyvinylglycine (AVG) application during near harvest period on ethylene biosynthesis and find out the most appropriate possible way to control the process for maximum prolonging the postharvest shelf -life of bananas. Results indicated that the most appropriate moment of AVG application is from the 74 th to 78 th days after formation of the last hand of a bunch has been finished as AVG showed some inhibition effects on ACC, ACC oxydase and ethylene synthesis. ACC, ACC oxydase and ethylene production of the fruits sprayed with AVG of 0.8 g/l on the 78 th day, harvested and stored at 13±1 o C for four weeks were 1.09 (nmol C 2 H 4 .g ) respectively while the ACC, ACC oxydase and ethylene production of non -treated fruits stored in the same conditions were 6.89 (nmol C 2 H 4 .g
