The leakage of solutes from cotyledons of soybeans (cv. Chippewa 64) was markedly stimulated by a chilling treatment (1 to 4 C) during the 1st minute of imbibition, but chilling after even 1 minute of water uptake resulted in little or no leakage increase. The respiratory rate of soybean particles was reduced more than 60% if a chilling treatment (15 minutes at 1 to 4 C) was given during the fi...

The peppers which were treated at ice-temperature for 6 hours and 1 mmol/L spermidine for 10 min, followed by cold storage (4 ̊C ± 1 ̊C) respectively were investigated. The results indicated that the chilling injury was delayed and reduced by ice-temperature and spermidine treatments. Comparing with control group, ice-temperature and spermidine exerted significant effects on reduction of ascorbic...

Hyperspectral images of cucumbers were acquired before and during cold storage treatment as well as during subsequent room temperature (RT) storage to explore the potential for the detection of chilling induced damage in whole cucumbers. Region of interest (ROI) spectral features of chilling injured areas, resulting from cold storage treatments at 0 C or 5 C, showed a reduction in reflectance i...

Chilling injury in cucumber (Cucumis sativus L.) is conditioned by maternal factors, and the sequencing of its chloroplast genome could lead to the identification of economically important candidate genes. Complete sequencing of cucumber chloroplast (cp)DNA was facilitated by the development of 414 consensus chloroplast sequencing primers (CCSPs) from conserved cpDNA sequences of Arabidopsis (A...

Chilling-sensitive fruit often produce a burst of ethylene when reconditioned at ambient temperature after cold storage. This has led some authors to propose that chilling injury (CI) may be induced by post-chilling ethylene production. To test this hypothesis we examined two tomato (Solanum lycopersicum L.) mutants, non-ripening (nor) and ripening-inhibitor (rin) that do not produce climacteri...

Freshly harvested tomato fruit (Solanum lycopersicum) were pre-treated with 0, 50, and 100 µM prohexadione-calcium (Pro-Ca) and then stored at 1 °C for 21 days to investigate the effect of Pro-Ca treatment on electrolyte leakage (EL), malondialdehyde (MDA), proline and total phenols contents, and activity of phenylalanine ammonia-lyase (PAL) in relation to chilling injury (CI).Treatment with Pr...

Most tropical horticultural commodities are sensitive to chilling temperatures. Therefore, chilling injury (CI) is a serious problem in the postharvest handling of tropical horticultural commodities. From the standpoint of CI, we can classify all horticultural crops into three categories: A) chilling resistant; B) chilling sensitive; and C) slightly chilling sensitive. The storage life of commo...
