Pomegranate is a kind of fruit with low temperature sensitivity. Abnormal low temperature can easily lead to chilling injury, which negatively impacts the appearance of fruit, accelerates browning and deterioration, as well as seriously reduces the consumption quality and commodity value of pomegranate. This study was carried out to determine the effect of methyl jasmonate on chilling injury of pomegranate during low temperature storage. The result showed that methyl jasmonate treatment effectively maintained edible quality of pomegranate, suppressed the polyphenol oxidase activity and the development of chilling injury index, and inhibited the decline of total phenol content and the increase of malondialdehyde content and cell membrane permeability. In addition, methyl jasmonate could also enhance the disease resistance of fruit by increasing the content of soluble protein, and effectively maintain the integrity of epidermal cell structure and tissue structure. Overall, the conclusion of this paper is that methyl jasmonate can be used as an effective means to suppress chilling injury in postharvest storage of pomegranate.

<p>Buah pisang nipah termasuk buah klimakterik yang  pematangannya akan berlangsung cepat jika disimpan pada suhu ruang. Penyimpanan suhu rendah merupakan salah satu teknik memperpanjang umur simpan buah pisang namun dapat menyebabkan  kerusakan berupa pencokelatan kulit buah yang dikenal sebagai salah satu gejala <em>chilling injury</em>. Penelitian ini bertujuan untuk mendapatkan informasi tentang pengaruh pengukusan dalam menurunkan gejala <em>chilling injury </em>serta mempertahankan mutu buah pisang nipah yang disimpan pada suhu rendah. Percobaan dilakukan menggunakan  rancangan acak lengkap dengan empat perlakuan dan tiga ulangan. Perlakuan terdiri dari pengukusan pada suhu 42oC selama 15 menit, 48oC selama 10 menit, 100oC selama 30 detik dan tanpa pengukusan. Parameter pengamatan terdiri dari indeks <em>chilling injury</em>, susut bobot, kekerasan buah dan total padatan terlarut. Hasil penelitian menunjukkan perlakuan pengukusan dapat mengurangi gejala <em>chilling injury </em>dan dapat mempertahankan buah pisang selama 15 hari penyimpanan. Pengukusan pada suhu 100oC selama 30 detik merupakan perlakuan terbaik. Perlakuan pengukusan tidak menurunkan kandungan total padatan terlarut dan berpengaruh tidak nyata terhadap peningkatan susut bobot serta penurunan kekerasan buah pisang nipah.</p><p> </p><p><strong>Steaming to Reduce the Symptoms of Chilling Injury and Maintaining Quality of  Banana CV. Nipah</strong></p><p>Nipah banana is a kind of climacteric fruit which is the ripening can be faster if its storage at room temperature. Low temperature storage is a way to prolong shelf-life but can caused peel browning, known as chilling injury symptom. This study was aiming to get information about steaming decreased chilling injury symptom and maintaining nipah banana quality at low temperature. The experiment was arranged in a randomized complete design with 4 treatments and 3 replication. Nipah bananas were steamed at 42oC 15 minutes, 48oC 10 minutes, 100oC 30 seconds and unsteamed. Chilling injury index, weight lost, firmnes and total soluble solid were measured. The result showed that steaming treatments decreased chilling injury symptom and maintained Nipah banana until 15 days storage. Steaming on 100oC,30 seconds was more effective to alleviate chilling injury symptom than others. No significant effect were found on weight loss, firmness and total soluble solid.</p><p><strong><br /></strong></p>

The effects of harvest maturity of mangos (Mangifera indica L.) on storage tinder various low-temperature regimes and the influence of storage on quality development during subsequent ripening at higher temperatures were investigated. The capacity for storage of mango fruit depended on harvest maturity, storage temperature, and the time of harvest within the season. Development of peel and pulp color, soluble solids concentration, pH, and softening in `Amelie', `Tommy Atkins', and `Keitt' mangos occurred progressively during storage for up to 21 days at 12C. Based on the level of ripening change that occurred during 12C storage, immature fruit showed superior storage capacity than fruit harvested at more-advanced stages of physiological maturity. On transfer to ripening temperatures (25C); however, immature fruit failed to develop full ripeness characteristics. Mature and half-mature fruit underwent limited ripening during storage at 12C, the extent of which increased with progressive harvests during the season. Ripening changes during storage for 21 days were less at 8 and 10C than at 12C. Chilling injury, as indicated by inhibition of ripening, was found at all harvest stored at 8C, and in early season harvests stored at 10C. Fruit from mid- and late-season harvests stored better at 10 than at 12C, with no apparent signs of chilling injury. Flavor of mangos ripened after low-temperature storage was less acceptable than of those ripened immediately after harvest. Suggestions are made for maximizing storage potential by controlling harvest maturity and storage temperature for progressive harvests throughout the season.

`Thompson' pink grapefruit (Citrus paradisi Macf.), waxed or film-wrapped, treated with thiabendazole (TBZ) or untreated, were used to determine the effect of high-temperature conditioning at 31C for 3 days on fruit during subsequent storage for 4 weeks at 1 or 10C. Chilling injury (CI) developed in all conditioned fruit stored at 1C, but was drastically reduced in film-wrapped compared to waxed fruit. Thiabendazole slightly reduced CI, and fruit held at 10C had fewer CI symptoms than those held at 1C for 4 weeks. Conditioning Florida grapefruit at 31C for 3 days did not allow subsequent storage at 1C without rind discoloration. Chemical name used: 2-(4'-thiazolyl)-benzimidazole (thiabendazol, TBZ).
