Effect of abscisic acid and methyl jasmonate preharvest applications on fruit quality and cracking tolerance of sweet cherry

Abstract

Rain-induced cherry fruit cracking is one of the most important problems in the cherry industry, and its occurrence causes significant economic losses. Sweet cherry (Prunus avium [L.] L.) is a non-climacteric fruit affected by both abscisic acid (ABA) and methyl jasmonate (MeJA) during development. The objective of this study was to evaluate the effect of these phytohormones on cracking susceptibility and quality parameters of sweet cherry fruit ('Bing'), located in the central region of Chile. During two seasons, independent pre-harvest applications of ABA (0.1 mM) and MeJA (0.4 mM) or both combined, at fruit developmental stages of fruit set or fruit color change, significantly reduced the number of mature cracked fruit after 6 h of immersion in water (p < 0.05). In both seasons the combinations of ABA and MeJA applied at fruit set reducing cracking index in an 87% compared to the control without compromising the weight or the diameter of the fruits. Moreover, in the second season ABA and MeJA applications at fruit set increased fruit firmness (11% and 6% respectively) and fruit color parameters regardless of the fruit stage at application, although slight decreases in soluble solids content were observed in most of the treatments.

Interactive effects of abscisic acid and nitric oxide on chilling resistance and active oxygen metabolism in peach fruit during cold storage

“…In our current study, it is worth pointing out that exogenous NO or ABA treatment was effective in reducing CI and delaying peach fruit softening. Similar results have been found in other cold‐sensitive fruits such as Hami melon, papaya, zucchini and sweet cherry . SSC and peel color are essential factors affecting fruit flavor and appearance and can be affected by fruit senescence.…”

“…Similar results have been found in other cold-sensitive fruits such as Hami melon, 35 papaya, 34 zucchini 15 and sweet cherry. 21 SSC and peel color are essential factors affecting fruit flavor and appearance and can be affected by fruit senescence. In this study, SSC in peach fruit increased, peaking on the fourth week and then decreased gradually over time during cold storage.…”

“…The concentrations of NO, c-PTIO, ABA and sodium tungstate were selected based on the results of previous reports. 7,[19][20][21] The NO solutions were prepared using the method described by Jing et al 7…”

Foliar Application of Calcium and Growth Regulators Modulate Sweet Cherry (Prunus avium L.) Tree Performance

“…Although cherry cracking incidence did not significantly decrease with spray treatments in both years, it was observed that also the AN-and ABA-treated fruits showed the least cracking index in 2015 and 2016 ( Figure 5). Reduced cracking index for ABA-treated 'Bing' cherry was reported by Balbontín et al [25]. An additional promising strategy to mitigate cherry cracking is AN, as had been reported by our research group for 'Skeena' and 'Sweetheart' cherry fruits [31].…”

Effect of some Biological Stimulants and Kaolin Particles Sprays on Fruit Retention, Productivity and Fruit Quality of Washington Navel Orange Trees

“…Kaolin sprays on navel orange in this experiment has delayed the ripening processes of orange and these results are in accordance with the work of on Balady mandarin and also are supported by the results of Maletiska et al (2015) on clingstone peach displaying a higher value of firmness for kaolin treated fruits compared to control. Balbontín et al (2018) concluded that application methyl Jasmonate on sweet cherry increased firmness of fruits indicating that Jasmonic acid influences physiological processes of ripening by delaying softening as it is involved in the regulation of cell wall metabolism genes.…”
