The chlorophyll fluorescence technique was evaluated as a possible predictive and nondestructive method to detect low-O2 and/or high-CO2 injuries in 'Conference' pears and 'Jonagold' apples stored in controlled atmosphere (CA). The fruits were kept at 0°C in air, 1% CO2 + 2% O2 or 3% CO2 + 1% O2 during five months. Fluorescence parameters of minimal fluorescence (Fo), maximal fluorescence (Fm), and potential quantum yield - (Fm-Fo):Fm, also denoted as Fv:Fm- as well as the incidence of browning disorders were evaluated at several times during storage. No incidence of browning disorders was observed in 'Jonagold' apples, however, they showed a decrease in Fv:Fm during storage time with no differences between the CA-conditions. Air-stored apples showed a higher decrease in Fv:Fm. On the other hand, 'Conference' pears kept in 3% CO2 + 1% O2 developed a lot of browning injuries such as core flush, flesh browning and cavities. Under this CA-condition, a pronounced decrease in the quotient Fv:Fm was observed already in the first 15 days of storage prior to the development of browning, and this behaviour remained during the whole storage period. The air-stored pears showed a similar behaviour as of the air-stored apples with a pronounced decrease in the Fv:Fm at the end of the storage period. The present results indicate that chlorophyll fluorescence is a promising technique to detect browning injuries in 'Conference' pears prior to their development.

ABSTRACT Controlled atmosphere storage allows for the long-term and short-term storage of fruit without a significant decrease in quality, resulting in a longer shelflife of fresh fruit. The Department of Horticulture at the West Pomeranian University of Technology in Szczecin conducted research on the effects of post-harvest precooling (3-4°C within two hours) and storage conditions (conventional cold room and controlled atmosphere storage) on fruit firmness, chemical composition, colour and weight loss. After six weeks of storage, it was found that the quality of fruit had declined. In comparison with fresh fruit, the harvest was found to have lost weight and darkened in colour. In addition, a decrease in firmness and the content of ascorbic acid and polyphenolic compounds was also observed. The fruits that were stored in a cold room with a controlled atmosphere and rapidly chilled immediately after harvest were the least affected. In addition, the research showed that there was a high correlation between the anthocyanin index and the polyphenol content in the fruits. To maintain the high quality of the fruit, the fruit must be very rapidly cooled soon after harvest and stored under optimal conditions - a cold room with a controlled atmosphere.

Peaches stored in air for 40 days at OC developed severe internal breakdown and poor quality after transferring them to 20C to ripen. Comparable fruit stored under controlled atmosphere (1% O2 + 5% CO2) and then ripened at 20C had no breakdown and retained good quality. Fruit stored under CA had less reducing sugars but more sucrose than air stored fruit. Fruit pH increased and titratable acidity decreased over a 40 day storage period. Citric acid increased slightly while malic acid decreased during storage. Little or no differences in overall acidity and individual organic acids existed between CA and air storage. Little or no change in individual phenolic acid content occurred during storage or between CA and air storage. Internal color darkened and became redder with storage. CA stored fruit was significantly firmer than air stored fruit. Sensory evaluation indicated CA stored fruit was more acidic, sweeter, and had better overall flavor than air stored fruit.

In both experiments. 20-apple samples from 6 commercial orchards were harvested and stored in 208 liter containers at 0C for 4, 6, and 8 months. Additional samples were removed from CA and held at 0C for 14 days before evaluation. Gas composition was measured and controlled 6 times per day using automatic control equipment. In the first experiment, samples were stored at constant 0.0% CO2 and one of three O2 regimes (constant 2.0%. 0.5 rising to 3.5%. or 3.5% falling to 0.5% O2). Apples stored at 3.5% falling to 0.5% O2 during the storage period were softer than apples held at constant 2.0% or those held at 0.5% rising to 3.5% O2 during the storage period. Variable O2 concentrations did not influence weight loss during storage and insignificant scald, flesh browning, core browning, rot, and low 02 injury were observed. In the second experiment, samples were stored at constant 2.0% O2 and one of three CO2 regimes (constant 0%, constant 5%. or 0% rising to 6% CO2). Constant 5% or rising CO2 conditions did not significantly influence flesh softening or weight loss during storage. Negligible CO2 injury was observed.

To investigate quality changes of garlic associated with cultivars and storage conditions, northern type `Seosan' and sub-tropical type `Daeseo' garlics were stored at controlled atmosphere (O2 3%, CO2 5%, -1 ± 1°C) condition, low temperature (-1 ± 1°C), and room temperature (20 ± 5°C). The rate of sprouting, weight loss, enzymatic pyruvic acid content, and degree of greening in crushed garlic were determined during storage. The rate of sprouting was higher in `Daeseo' than in `Seosan' garlic in all storage conditions. Sprouting was effectively suppressed in low temperature and controlled atmosphere storage. Weight loss in `Daeseo' garlic was higher than in `Seosan' garlic. Enzymatic pyruvic acid (EP) contents increased for 3 months storage period, and then decreased gradually as the storage period was prolonged at room or low temperatures. However, EP content decreased dramatically during storage under CA condition in both cultivars. When garlic bulbs were crushed, greening appeared in the garlic stored at low temperature for more than one month. However, greening did not occur in the crushed garlic bulbs stored in CA condition.

Creston is a new high-quality apple cultivar ripening 6 d before Red Delicious. It is large-fruited and similar to Jonagold in appearance but possesses better firmness and storage quality. It can be held for 8 wk in air storage (0 °C) and 4–5 mo in controlled-atmosphere storage. Key words: Malus domestica Borkh., dessert apple, cultivar descriptionnot available

The effects of picking date, storage atmosphere, storage temperature, and delayed storage on the behavior of Starking Delicious apples (Malus sylvestris Mill.) were studied over a 3-yr period. Regular cold storage, controlled atmosphere storages of 2% CO2 + 3% O2, and 0% CO3 + 3% O2, delayed storage of 48 h at 20 C prior to cold and controlled-atmosphere storage and temperatures of 0 and − 1 C were the treatments used. Temperature showed little or no effect on firmness, acidity, soluble solids, core browning, or flesh browning but controlled atmosphere treatments at − 1 C markedly reduced the incidence of scald compared with 0 C. Apples from the 2% CO2 + 3% O2 atmosphere had significantly more core browning than those from the 0% CO2 + 3% O2 atmosphere. The fruit picked later had less core browning than that picked 1 wk earlier when stored in the 2% CO2 + 3% O2 atmosphere. Fruit stored in a 2% CO2 + 3% O2 atmosphere was firmer than that in 0% CO2 + 3% O2.
