“…The BPLS associated with the BG method were less pronounced for all sample groups and seasons. Other methods consisting of modifying the atmosphere and achieving low O 2 levels to reduce postharvest bitter pit have also been reported (Hewett, 1984;Hewett and Thompson, 1989;Khan et al, 2006;Val et al, 2009;Pesis et al, 2010). Pesis et al (2010) and Val et al (2009) reported that low O 2 and 20 C short-term pre-treatments prior to cold storage, could help to reduce bitter pit during cold storage.…”

“…In contrast, postharvest reductions in bitter pit have been reported in association with modified atmospheres and low O 2 levels (Khan et al, 2006;Torres and Alegre, 2012). Pesis et al (2010) and Val et al (2009) showed that pre-treatments prior to cold storage involving low O 2 and short-term storage at 20 C were able to reduce the incidence of apple scald and bitter pit during cold storage.…”

A B S T R A C TAn effective method for predicting bitter pit incidence implemented before harvest could be a useful instrument for both the fruit industry and growers. Between 2009 and 2011, various methods for the prediction of bitter pit were evaluated at 60, 40, and 20 days before harvest (dbh) and at a commercial harvest in 'Golden Smoothee' apples. Four methodologies, two new ones (the development of natural bitter pit before harvest through the 'passive method' and bagging detached fruit before commercial ripening), and two of known efficacy under other conditions (infiltration with magnesium salts and maturity enhancement with ethephon dips) were assessed. To estimate the predictive accuracy of each method, bitter pit-like symptoms were related to the postharvest presence of bitter pit. The 'passive method' assesses bitter pit-like symptoms that appear naturally in fruit once they are picked from the tree, and left at room temperature during its evaluation. The 'passive method', as well as the infiltration with magnesium salts and ethephon dips, recognized bitter pit-like symptoms approximately 5-7 days after sampling (at 40 dbh) and showed significant correlation with the incidence of bitter pit after three months of cold storage. The 'passive' and 'ethephon' methods were also validated over two additional seasons in 30 and 16 different orchards, respectively. The results of these validations supported the efficacy of using the 'passive method' as the main method for predicting bitter pit, without having to use either reactive products or specialized equipment.

“…The alternative to the 1-MCP treatment is low O 2 storage for 10 days at 20 °C, before long-term storage at low temperature (0-4 °C) (Pesis et al, 2010;Val et al, 2010).…”

Bitter pit is a physiological disorder that significantly reduces the quality of apples. Although it has been detected since the beginning of the last century, still there is little known about the mechanism of its occurrence. According to numerous studies, bitter pit is formed as a result of calcium deficiency in the fruit. Some authors cite the high concentration of gibberellins, later in the production season, most probably caused by excessive activity of the roots, as the chief causative factor. Beside Ca, there are several factors that can also contribute to its development, like imbalance among some mineral elements (N, P, K and Mg), cultivar, rootstock, the ratio of vegetative and generative growth, post-harvest treatments and the storage methods. There are some prediction models available that can estimate the risk of bitter pit in apples, but even those are not always reliable. The aim of this review was to encompass the pre and postharvest factors which cause bitter pit and point out the directions for solving this problem.

“…For mineral element determination, fruits were carefully washed as previously described (Val et al, 2010), and a 1-cm transverse section of the fruit was cut at the equator, the skin was carefully separated from the cortex, and aliquots of each tissue were prepared for analysis. For tissue element determination, peels were finely cut (< 1 mm thick) and mixed.…”

Laboratory and field experiments were carried out with apples (Malus x domestica Bork) cv. 'Golden Reinders', to assess the efficacy of sodium salt of carboxymethyl ether of cellulose (0.5%, CMC) as an adjuvant for Ca spray formulations containing either Cachloride or Ca-propionate as active ingredient (120 or 250 mM Ca). This additive significantly increased the retention of Ca-containing solutions by the apple skin and prolonged the process of drying of the solution at room temperature. Four days after immersion of apples in 0.5% CMC plus CaCl 2 or Ca-propionate solutions (120 and 250 mM Ca) significant Ca increases were recorded in the peel and cortex of treated fruits. Application to apple trees of in-season sprays containing 250 mM CaCl 2 plus 0.05% Tween 20, Ca-propionate (120 and 250 mM Ca) plus 0.5% CMC or 250 mM CaCl 2 plus 0.5% CMC had no impact on fruit yield and quality, but significantly limited the rate of bitter pit incidence during the following 3-month cold-storage period. Evidence is provided that addition of appropriate adjuvants to Ca sprays can favour the distribution of Ca into the apple fruit and help to reduce the incidence of Ca-related disorders over the postharvest cold-storage period.

Low oxygen treatment prior to cold storage decreases the incidence of bitter pit in ‘Golden Reinders’ apples

Abstract: Application of a LOT prior to cold storage may be a promising strategy to reduce the incidence of BP and preserve fruit quality, which should be further investigated.
