“…5, PC2). An increase in sweetness and a decrease in acidity during cold storage has been demonstrated for several cultivars (Watada et al, 1981;Tu et al, 1997). The results signify that the cultivars 'Retina', 'McShay', 'Saturn' and 'Dayton' do not retain quality well during storage since they develop an overripe flavour and a mealy texture with less sweetness and apple flavour.…”

Twenty-two scab-resistant apple cultivars were harvested in autumn 1999 and evaluated for sensory quality the following October, November and December. Multivariate analysis was effective in describing the complex relationships and variability among the numerous attributes used to characterise apple quality. Crispness, mealiness, skin toughness, apple flavour, sweetness, unripe flavour and overripe flavour were informative attributes describing the variation in the sensory quality. Texture attributes, apple flavour and overripe flavour were affected by storage. Extended storage resulted in an increase in mealiness and overripe flavour and a decrease in crispness, juiciness and apple flavour. Many potential scab-resistant cultivars were suitable for consumption in October: 'Dayton', 'Primicia', 'Retina' and 'Realka'; in November: 'Merlijn', 'Saturn', 'Initial', 'Realka', 'Rajka' and 'Rubinola'; and in December: 'Otava', 'Ecolette', 'Rajka', 'Rubinola', 'Delorina', 'Initial' and 'Resista' and 'Topaz'. This study gives a sensory characterisation of scab-resistant cultivars as an indicator of suitability for commercial growing and marketing of low-input apple cultivars. ((;)

“…data). The effectiveness of CA in reducing softening is cultivar dependent (Dilley et al 1989), and influenced by: the O 2 and CO 2 concentration (Kidd & West 1933;Hertog et al 2001); time between harvest and establishment of CA conditions (Dilley et al 1989); storage temperature (Kidd & West 1933); fruit maturity (Tu et al 1997); and exogenous ethylene concentration in store (Liu 1985).…”

Postharvest softening of apple (Malus domestica (Borkh.)) fruit is a serious problem for growers in many countries, including New Zealand. To reduce this problem considerable research has been undertaken to determine the biological causes of softening so that this process can be managed or controlled more effectively. This review describes the pattern of softening for harvested apple fruit, and how it is influenced by different preharvest, atharvest, and postharvest factors. Information is also given on the likely physiological and biochemical causes of apple softening, such as fruit anatomy and cell packing, modification of the cell wall and membranes, changes in cell turgor, and the role of ethylene and other growth regulators. Despite many softening studies, there is still a poor understanding of what causes firmness variation in the marketplace. Until this understanding is improved, apple producers will continue to struggle to meet market requirements for texture.

“…Harvest date was not correlated with fruit firmness in 'York' apples stored in air, but harvest date and the firmness of fruit stored under CA conditions were negatively correlated (Ingle et al, 2000). In studies performed within a single year, early-harvested 'Cox's Orange Pippin' fruit were firmer than late-harvested fruit kept in air or in CA storage (Tu et al, 1997;Johnston et al, 2002). On the other hand, Knee and Smith (1989) found that the extent to which the sensory firmness of 'Cox's Orange Pippin' fruit was affected by harvest date after CA storage varied from year-to-year.…”
