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

`Ginger Gold' is a high-quality summer apple with potential for processing and fresh markets. Although summer cultivars typically exhibit poor storage quality, data from three seasons indicate that storage potential is high for `Ginger Gold' in low-O2 controlled atmosphere storage. In 1995, fruit harvested 25 Aug. (85N) were stored in air (0 °C), 3% O2/<2% CO2 (0 °C) or 0.7% O2/1% CO2 (0 °C) for 4 or 7 months. After 4 months, firmness of fruit stored in air, 3% O2 and 0.7% O2 were 53N, 67N, and 80N, respectively. After 7 months, apples stored in air were soft (45N) and had excessive decay (55%), cracking (48%), and breakdown (61%). However, fruit stored in 0.7% O2 were of good quality (76N, 4% decay, 4% cracking, and no breakdown). No low-oxygen injury occurred. Apples were harvested on 14, 21 and 28 Aug. 1996 (85N, 80N, and 76N, respectively) and stored in air (0(C), 1.5% O2/1% CO2 (0(C), 1% O2/1% CO2 (0 °C) or 0.7% O2/1% CO2 (0 °C). Soluble solids were (9.5 at harvest, with starch scores of 3.5–4.5. After 2 months in air the firmness began to decrease rapidly and after 4 months ranged from 49–62N. Apples stored for 4 months in CA (≤1% O2) maintained firmness >70N. In 1997, fruit were harvested 14, 21, 28 Aug. and 4 Sept. (102, 96, 89, and 82N, respectively and 12–13.3 °Brix). After 4 months in CA, fruit were still of high quality (>83N, > 13.2 °Brix).

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.
