“…Susceptibility of apple fruit to low O 2 injury in CA storage was found to be positively correlated with resistance of the fruit towards the diffusion of gases. For a given strain/cultivar, resistance to gas diffusion was found to be affected by fruit's maturity, duration of storage and whole fruit volume (Park et al 1993). It was noticed that, 'Marshall' strain of McIntosh apple had higher resistance and thereby it showed more susceptibility to low O 2 injury as this strain accumulated ten times higher ethanol when compared with 'Rogers' (another strain of McIntosh apple) (Park et al 1993).…”

Role of internal atmosphere on fruit ripening and storability—a review

Concentrations of different gases and volatiles present or produced inside a fruit are determined by the permeability of the fruit tissue to these compounds. Primarily, surface morphology and anatomical features of a given fruit determine the degree of permeance across the fruit. Species and varietal variability in surface characteristics and anatomical features therefore influence not only the diffusibility of gases and volatiles across the fruits but also the activity and response of various metabolic and physiological reactions/processes regulated by these compounds. Besides the well-known role of ethylene, gases and volatiles; O 2 , CO 2 , ethanol, acetaldehyde, water vapours, methyl salicylate, methyl jasmonate and nitric oxide (NO) have the potential to regulate the process of ripening individually and also in various interactive ways. Differences in the prevailing internal atmosphere of the fruits may therefore be considered as one of the causes behind the existing varietal variability of fruits in terms of rate of ripening, qualitative changes, firmness, shelf-life, ideal storage requirement, extent of tolerance towards reduced O 2 and/or elevated CO 2 , transpirational loss and susceptibility to various physiological disorders. In this way, internal atmosphere of a fruit (in terms of different gases and volatiles) plays a critical regulatory role in the process of fruit ripening. So, better and holistic understanding of this internal atmosphere along with its exact regulatory role on various aspects of fruit ripening will facilitate the development of more meaningful, refined and effective approaches in postharvest management of fruits. Its applicability, specially for the climacteric fruits, at various stages of the supply chain from growers to consumers would assist in reducing postharvest losses not only in quantity but also in quality.

“…Low permeance to gas exchange has been implicated in greater susceptibility of fruit to low O 2 injury (Park et al, 1993). Less is known about possible relationships between permeance and high CO 2 injury.…”

The incidence and severity of “`Braeburn' browning disorder” (BBD), a CO2-induced disorder of `Braeburn' apple (Malus ×domestica Borkh.), vary markedly with production district and orchard block. We investigated the effects of harvest date, blush, and crop load on fruit maturity, minerals, skin permeance, and BBD incidence. Incidence of BBD was higher in late-than in early-harvested fruit and in fruit on light than on heavily cropping trees, but blush intensity did not influence susceptibility to the disorder. Fruit maturity factors were affected by region, harvest date, blush type, and crop load, but no consistent relationships between these factors and BBD occurrence were found. Concentrations of Ca, Mg, and/or K were influenced by harvest date, blush type, and crop load, and skin permeance to gas exchange was affected by growing region and blush type, but not by harvest date or crop load. However, no physiological or mineral factor measured in this study was strongly correlated with susceptibility of fruit to BBD. Fruit from orchards that have a history of susceptibility to BBD, or subjected to adverse harvest date, regional, crop load, microclimate, and seasonal influences, should be segregated at harvest, and should not be held in controlled-atmosphere (CA) storage. Crop load should be managed to reduce the occurrence of biennial bearing.

“…In apples and pears, resistance to gas diffusion varies with cultivar, with picking date and with storage duration (Park et al, 1993;Schotsmans et al, 2004). The resistance to gas diffusion increased during fruit growth and maturation, reaching a maximum near harvest maturity (Park, 1991).…”
