“…Bizjak et al (2013) reported that L* values decreased during advanced maturity in Braeburn apples, indicating darker fruit peels. Decreasing L* values were also reported with postharvest MeJA treatments in Golden Delicious and Fuji apples (Fan et al, 1998;Fan and Mattheis, 1999) and with preharvest treatments in Cripps Pink apples (Shafiq et al, 2013). Similarly in the present study, parameter L* decreased linearly with MeJA treatments regardless of the application regime.…”

The present study was carried out to determine the effects of methyl jasmonate (MeJA) treatments on the fruit peel color parameters, anthocyanin content, ethylene biosynthesis, phenolic content, and antioxidant capacity of Braeburn apples. Experimental trees were treated with 1120, 2240, or 4480 mg L-1 MeJA at 1-and 2-week intervals between the 105th and 175th days of growth after full bloom. L* and hue decreased linearly with increasing MeJA concentrations in both experimental years. While MeJA treatments did not cause significant changes in chroma, except for in the final harvest in 2010, it decreased chroma values significantly on all sampling dates of 2011. Anthocyanin content, internal ethylene concentration, phenolic content, and antioxidant capacity increased linearly with increasing MeJA concentrations, regardless of the application interval: MeJA treatments with 1-week intervals were found to be as effective as those with 2-week intervals. Although MeJA treatments increased ethylene biosynthesis, they did not cause any softening; on the other hand, fruit firmness increased linearly with increasing MeJA concentrations. Preharvest MeJA treatments can be a good management strategy for red peel color development and fruit firmness preservation in Braeburn apples. Although both application regimes of MeJA significantly increased red color development, the treatments with 1-week intervals were found to be more effective than 2-week intervals with regard to phenolic content and antioxidant capacity.

“…Increasing MeJA treatments linearly increased the total phenolics contents of apples (Table 2). Shafiq et al [26] also reported increased flavonoid levels Downloaded by [Selcuk Universitesi] at 10:58 07 February 2015 with pre-harvest MeJA treatments in "Cripps Pink" apples. Similarly, pre-harvest MeJA treatments increased the flavonoid levels in blueberries, [27] blackberries, [28] and grapes.…”

The present study was conducted to investigate the effects of pre-harvest methyl jasmonate treatments on peel color formation, total anthocyanin, total phenolics, total antioxidant capacity, and other selected fruit quality parameters of "Fuji" apples. Results revealed significant decreases in color parameters (L * , chroma, and hue values) with methyl jasmonate treatments. Total anthocyanin, total phenolics, and total antioxidant capacity of methyl jasmonate-treated fruits were significantly higher than control fruits. Methyl jasmonate concentrations increase linearly with increase in total anthocyanin, total phenolics, and total antioxidant capacity with high correlations. Ethylene synthesis-promoting impact of methyl jasmonate increased with increasing implementation doses. Methyl jasmonate treatments also increased fruit flesh firmness. While 1120 and 2240 mg/L methyl jasmonate treatments did not cause any significant changes in the starch degradation, 4480 mg/L methyl jasmonate treatment delayed the starch degradation. All methyl jasmonate treatments did not cause any or much significant changes in fruit mass, geometric mean diameter and soluble solids content of the fruits but yielded significant increase in titratable acidity values.

“…These characteristics vary based on growth period, soil and ecological conditions, plant nutrients, type of production (organic or inorganic), harvest time and other cultural practices (Meashami, 2011). Other researchers (Zhang and Whiting, 2011;Shafiq et al, 2013) reported direct impacts in growth regulators on physical, mechanical and biochemical properties of the fruits.…”

“…Sweet cherry is a non-climacteric fruit and therefore rapidly losses peel color and flesh firmness because of higher post-harvest respiration rates. Despite some contrary opinions (Remon et al, 2003), various researchers (Estia et al, 2002;Shafiq et al, 2013) reported that such losses in peel color and flesh firmness were related to phenolics, antioxidants, anthocyanins and pectins in fruits (Crisosto et al, 2001). These characteristics vary based on growth period, soil and ecological conditions, plant nutrients, type of production (organic or inorganic), harvest time and other cultural practices (Meashami, 2011).…”

Background: AVG is an organic ethylene inhibitor. AVG treatments retarded the ripening process, increased fruit sizes and delayed loss of postharvest fruit flesh firmness by inhibiting ethylene. MeJA is a natural plant growth regulator and plays a regulatory role in various metabolic reactions. Apart from its role in fruit ripening, cell activities like anthocyanin and carotenoid synthesis and inhibitive role in aromatic material formation, chlorophyll and lycopene production. Materials and Methods:The present study was conducted to determine the effects of pre-harvest aminoethoxyvinylglycine (AVG) and methyl jasmonate (MeJA) treatments on bioactive compounds, mineral nutrients and other fruit quality characteristics of 'North Wonder' sweet cherries variety in 2011. AVG was sprayed on experimental trees at 125 mg L -1 dose in two different periods i.e. 3 weeks and 2 weeks before the anticipated harvest date. MeJA was applied 3 week before the anticipated harvest date at a dose of 2240 mg L -1 . Results: MeJA significantly increased fruit weight and geometric mean diameter. AVG significantly decreased fruit weight and flesh/stone ratio, significantly increased L*, chroma and hue angle values. Effects of both AVG and MeJA on flesh firmness were also found to be significant. While soluble solids concentration and pH values significantly decreased with AVG treatment, titrate acidity significantly increased. Both AVG and MeJA treatments significantly decreased total phenolics (TP), total antioxidant capacity (TAC) and total anthocyanin (TA). Effects of AVG on such decreases in TAC and TA were more efficient than MeJA. While the effects of both AVG and MeJA on iron content were significant, effects of only MeJA on nitrogen and phosphor contents were found to be significant. Conclusion: Growth regulators significantly decreased bioactive compounds. AVG was more effective in such decreases than MeJA.

Time of methyl jasmonate application influences the development of ‘Cripps Pink’ apple fruit colour

Abstract: A single pre-harvest spray of MJ (10 mmol L(-1)) at 169 DAFB or MJ (5 mmol L(-1)) at 186 DAFB was effective in improving the red blush and export grade fruit through accumulation of flavonoids in fruit skin without adversely affecting quality at harvest.
