“…This indicates both an increase in the crop productivity (overall yield) and a hastening of fruit ripening (higher yields in the first and second harvest, and reduction in the third). These results confirm the ethephon property of inducing an earlier color change in fruit peel, as reported by Powers and coauthors [19], Carvalho and coauthors [20], Delú Filho and coauthors [21], and Steffens and coauthors [22]. Moreover, the harvest of a higher fruit proportion in the Brazilian Archives of Biology and Technology.…”

The objective of this work was to evaluate different concentrations of ethephon on Fortune plum ripening, also observing the effect of ethephon concentration on the fruit parameters of yield, soluble solids (SS), titratable acidity (TA), SS/TA ratio, firmness, wooliness, diameter, length, and average fruit mass at harvest and post-harvest. The experimental design was completely randomized with five treatments and four replications, each experimental unit consisting of four plants. The ethephon concentrations of zero, 100, 200, 300, and 400 mg•L -1 were applied on the plums 20 days before the estimated harvest time. The results indicated that ethephon application induced a higher fruit yield in earlier harvest time, but with no effect on overall yield. Relative to the quality characteristics, the application of ethephon induced a reduction of fruit firmness, soluble solids content, and titratable acidity. Fruit length was not affected. The parameters of soluble solids, titratable acidity, and firmness presented a negative significant correlation with the ethephon dose. Relative to post-storage evaluation, the ethephon application induced a higher SS/TA ratio, and lower HIGHLIGHTS• Several ethephon concentrations were applied in pre-harvest on Japanese plums.• The quality characteristics of the plums prior and after cold storage were evaluated.• Ethephon use hastened the ripening of the fruits, with no effect in overall yield.• Some quality characteristics were influenced by ethephon, both in harvest and after storage.

“…In the 2015/16 harvest, the SS content was higher in control treatment fruits and in fruits that received mixed AVG application combined with ethephon (Table 3). According to Steffens et al (2011), high SS values may be related to high content of soluble pectins, since these fruits had the lowest pulp firmness values and lower pulp penetration and skin rupture strength (Table 4), demonstrating faster ripening of control treatment fruits. On the other hand, after the cold storage period, TA and SS/TA ratio were not influenced by treatments in both harvests (Table 3).…”

The aim of this work was to evaluate the effect of single and multiple pre-harvest spray aminoethoxyvinylglycine (AVG) applications with or without ethephon, in ‘Baigent’ apple trees cultivated under anti-hail screen and harvesting date on fruit quality after storage. The experiment was conducted in a commercial orchard in the municipality of Vacaria/RS, in the 2014/15 and 2015/16 harvests. Treatments consisted of: control (plants sprayed with water); AVG (125 mg L-1, 30 days before the predicted harvest date; BPHD); ethephon (120 mg L-1, seven BPHD); AVG (62.5 mg L-1 + 62.5 mg L-1, 30 and 20 BPHD); AVG (62.5 mg L-1 + 62.5 mg L-1, 30 and 20 BPHD) + ethephon (120 mg L-1, seven BPHD). Fruits of all treatments were harvested at commercial harvest (harvest 1) and after 14 days (harvest 2). Fruits were evaluated after four months of cold storage (0.5 °C ± 0.2 °C and RH 92 ± 5%). The use of AVG, regardless of single or multiple applications, reduced ethylene production rate, skin yellowing, farinaceous pulp and senescent degeneration incidence and maintained higher pulp firmness values and pulp penetration and skin rupture strength. Ethephon provided fruits with higher farinaceous pulp incidence. Fruit treated with AVG, regardless of single or multiple application and combination with ethephon, presents better quality after cold storage.

“…In fruit growing, biostimulants that inhibit the synthesis or action of ethylene have been used to retard ripening and preserve fruit quality during storage. In plums, Steffens et al (2011) found that the preharvest application of aminoethoxyvinylglycine (AVG) and gibberellic acid (GA 3 ) influenced fruit quality after refrigerated storage when applied alone. Luo, Chen and Xie (2011) verified the effect of salicylic acid on plums; the treated fruits presented a delay in the climacteric peak and the inhibition of respiration and ethylene production due to delayed polyphenoloxidase (PPO) and peroxidase (POD) activity and lower polyamine (PA) levels.…”

The use of extracts of algae in agriculture has been growing because of their benefits to plant development and production. The objective of this study was to evaluate the effects of Ascophyllum nodosum extract on the postharvest quality of ‘Irati’ and ‘Reubennel’ plums and on the incidence of brown rot. The treatments consisted of concentrations of 0, 0.1, 0.2, 0.3 and 0.4 mL L-1 of a commercial product containing algae extract (Algamare®) that were applied to the fruits by immersion. The fruits were then stored for 15 (cv. Irati) or 30 days (cv. Reubennel) at 2.5 °C and 90% RH and for two additional days at ambient conditions for further physicochemical analysis. A batch of ‘Reubennel’ plums was inoculated with Monilinia fructicola and kept for seven days in a cold room and an additional nine days at room temperature to evaluate the occurrence of brown rot. The postharvest application of the extract at a concentration of 0.4 mL L-1 altered some of the physicochemical characteristics of the fruit after storage; an increase in the total phenolic compound content and PG activity were observed in ‘Irati’ plums. Reubennel fruits had higher titratable acidity, a lower TSS/TA ratio, lower pulp firmness and higher PME activity. The most significant effect was observed with the application of A. nodosum extract at 0.4 mL L-1, which significantly reduced the incidence and severity of brown rot in the inoculated fruits and had a similar control effect as the application of the fungicide iprodione.
