A ‘scald-like’ controlled atmosphere storage disorder of Empire apples — a chilling injury induced by CO2

Low temperature disorders of nectarines are thought to be expressions of chilling injury. Chilling injury is a form of stress usually associated with increased synthesis of ethylene and its immediate precursor, aminocyclopropane-1-carboxylic acid (ACC). However, other mechanisms for the development of chilling injury have been proposed. To help determine the nature of the processes leading to chilling injury in nectarines (Prunus persica) and how the gaseous composition of the storage atmosphere effects the development of low temperature disorders, levels of ACC and conjugated ACC were measured in fruit of the cv. Arctic Snow. These compounds were measured in fruit ripened at 20°C immediately after harvest, in fruit on removal from cold storage and in fruit ripened at 20°C following cold storage. During storage, fruit were kept at 0°C in the 4 following atmospheres: air; air + 15% CO2; air + 15 µL/L ethylene; and air + 15% CO2 + 15 µL/L ethylene. Concentrations of ACC remained low in all treatments and no significant changes in ACC levels due to added ethylene or CO2 were observed. Concentrations of conjugated ACC were about 10-times that of ACC and again were not influenced by the composition of the storage atmosphere. No significant changes in either ACC or conjugated ACC were observed until after flesh bleeding, the major symptoms of low temperature disorder expressed in these fruit, had begun to appear. It was concluded that disorders in nectarines stored at low temperatures are not a stress response involving a disruption of ethylene metabolism but may be associated with differential changes in the metabolism of enzymes associated with normal ripening.

Atmosphere Storage

Snap bean (Phaseolus vulgarisL.) is sensitive vegetable which can develop chilling injury when stored at low temperatures. This study was conducted to investigate the effect of controlled atmosphere (CA) (2.5±0.5 %O2, 5±0.5 %CO2) and 1-methylcyclopropene (1-MCP) (0.5 μL/L) on chilling injury (CI) of snap bean during 35 days storage at 0 °C. The results showed that CA and 1-MCP reduced chilling injury symptoms, however, the CA combined 1-MCP treatment which delayed the respiration peak appeared and the chilling injury index achieved 1.9. The treatment decreased electrolyte leakage, malondialdehyde content and activities of PPO, which were significantly lower than CA and 1-MCP singly. These results suggested that combination of CA and 1-MCP treatment is promising treatment for alleviating chilling injury of snap bean stored at 0 °C which extending the shelf-life.

Atmosphere Storage

Pleospora herbarum (Fr.) Rabh., a fungus not previously recorded from apples in Canada, was isolated from a surface rot that developed on the McIntosh cultivar in controlled atmosphere storage in Kelowna, British Columbia. The isolate of P. herbarum failed to infect sound McIntosh apples, but did rot areas of the fruit that had been subjected to injury from incipient freezing. It was concluded that this storage rot developed on fruits that had suffered chilling injury when storages were being filled.

Atmosphere Storage

California grown `Hass' avocado fruit were stored at 5C, in air or a controlled atmosphere (CA) of 2% oxygen and 5% carbon dioxide. Fruit were evaluated at 0, 3, 6, and 10 weeks, both immediately upon removal from storage and after 5 days at 20C. Severe chilling injury developed in the air-stored fruit after six weeks, while only moderate symptoms were observed in CA stored avocado fruit after 10 weeks. Lipid peroxidation breakdown products increased during storage and ripening in both air and CA treatments. Sterols, sterol esters, glycolipids, and phospholipids were analyzed. There was a shift in composition during storage towards increasingly saturated fatty acids. The fatty acid shift was greater in air, than in CA stored fruit. Results will be discussed concerning their relevance to chilling injury development.

And Storage

A storage disorder of sweet cherries referred to as surface pitting is described and illustrated. Different handling, packaging and storage treatments influenced the amount of the disorder, but did not prevent it. Storage at 0 C or lower resulted in a higher incidence of the disorder than storage at a temperature several degrees higher. Neither mineral foliar sprays nor controlled atmosphere storage were effective in preventing surface pitting, and hydrocooling increased it.
