A number of abiotic shocks (e.g. heat-shock) applied before chilling have previously been shown to increase the chilling tolerance of cucumber and rice seedlings and of tomato fruit. The subsequent rate of radicle growth after chilling of these seedlings is a sensitive measure of chilling injury as is the subsequent increase in ion leakage from chilled discs of tomato pericarp fruit tissue. Dat...

The effect of rapid chilling of pork carcasses on bacterial populations was examined. Two regimes of rapid chilling were applied: treatment 1 (at –31°C in the first 3 h of chilling, and then at 2–4°C till 8 h post-mortem) and treatment 2 (at –31°C in the first 3 h of chilling, and then at 2–4°C till 24 h post-mortem). Microbiological sampling of pork carcasses was obtained by swabbing. Swab sam...

Abstract Improving chilling tolerance in cold-sensitive crops, e.g., tomato, requires knowledge of the early molecular response to low temperature these under-studied species. To elucidate responding processes and regulators, we captured transcriptional at 30 minutes 3 hours shoots roots tomato post-chilling from 24°C 4°C. We used a pre-treatment control concurrent ambient reveal that majority ...

Chilling is a common abiotic stress that leads to economic losses in agriculture. By comparing the transcriptome of Arabidopsis under normal (22 degrees C) and chilling (13 degrees C) conditions, we have surveyed the molecular responses of a chilling-resistant plant to acclimate to a moderate reduction in temperature. The mRNA accumulation of approximately 20% of the approximately 8,000 genes a...

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...

Winter chilling is of central importance in the phenology of temperate annual and perennial plants. Chilling accelerates flowering through the process of vernalization and breaks both bud and seed dormancy, permitting the onset of growth in the spring. The quantitative effects of chilling in floral promotion in winter annual Arabidopsis accessions are well-documented, but very little is known a...

The proportion of labeled (14)C-glycerol incorporated into phospholipids and the fatty acid composition of three phospholipids in germinating seeds and seedlings of chilling-sensitive lima beans (Phaseolus lunatus L.) and chilling-resistant broad beans (Vicia faba L.) and peas (Pisum sativum L.) at 10 and 25 C were determined. During the imbibition of seeds (first 24 hours), lima beans were sen...

The effect of evaporative air chilling on quality of fresh chicken carcasses was compared with air chilling as reference method. Cooling efficiency and total heat loss were significantly higher for evaporative air chilling. The chilling method was of great importance for weight loss. Chicken chilled in cold air lost considerably more weight than chicken cooled by evaporative air chilling; the d...

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...

To elucidate how physiological and biochemical mechanisms of chilling stress are regulated by abscisic acid (ABA) pretreatment, pepper variety (cv. 'P70') seedlings were pretreated with 0.57 mM ABA for 72 h and then subjected to chilling stress at 10°/6°C (day/night). Chilling stress caused severe necrotic lesions on the leaves and increased malondialdehyde and H(2)O(2) levels. Activities of mo...
