Chilling-induced photooxidation was studied in detached leaves of chilling-sensitive (CS) cucumber (Cucumis sativus L.) and chilling resistant (CR) pea (Pisum sativum L.). The rates of photosynthesis and respiration, measured as O(2) exchange, were found to be comparable in the two species over a temperature range of 5 to 35 degrees C. Chilling at 5 degrees C for 12 hours in high light (1000 mi...

Winter chilling is critical for flowering and fruiting of many temperate fruits, with evidence that blackcurrant (Ribes nigrum L.) cropping has been adversely affected by warm winters. Accurate models of chill accumulation in blackcurrant are required so that breeding strategies can be formulated for the generation of new cultivars with resilience to future climates. Existing models for chill a...

Direct water immersion chilling is used widely in the poultry plants because of higher heat transfer rate. However, post-mortem state of poultry muscle, extent of water uptake by carcasses prior to deboning, and marination has been one of the largest sources of inconsistency in marinated product quality and has become a problem for producers of marinated broiler meat. The effect of Ultra-rapid ...

A chilling-sensitive mutant of Arabidopsis thaliana was isolated and subjected to genetic, physiological, and biochemical analysis. The chilling-sensitive nature of the mutant line is due to a single recessive nuclear mutation at a locus designated chs1. In contrast to wild-type plants, which are not adversely affected by low temperatures, the chs1 mutant is killed by several days of exposure t...

The effect of chilling on photosystem II (PSII) efficiency was studied in the variegated leaves of Calathea makoyana, in order to gain insight into the causes of chilling-induced photoinhibition. Additionally, a relationship was revealed between (chilling) stress and variation in photosynthesis. Chilling treatments (5 degrees C and 10 degrees C) were performed for different durations (1-7 d) un...

To study the effects of chilling on dormancy breaking and the increased germination characteristics of Nepeta (germination percent and speed, seedling length, vigor index, wet and dry weight), a factorial experiment in a completely randomized design with 4 replications was implemented in a laboratory in 2014. Factor A was the chilling treatment in three levels (control, one-month and two-month ...

Three poultry chilling methods, namely, water chilling (WC), air chilling (AC), and evaporative air chilling (EAC), were compared to evaluate their effects on broiler breast meat quality and consumer sensory characteristics. A total of 189 birds were processed with 1 of the 3 chilling methods. One-third of the birds were hard scalded (57.7°C, 120 s) and subjected to WC (an ice slurry immersion ...

Watermelon [Citrullus lanatus (Thunb.) Matsum. & Nakai] is one of the Cucurbitaceae species and subtropical crops that exhibit chilling injury (CI) when exposed to low temperatures. Watermelon seedlings were tested for chilling tolerance using methods modified from cucumber. Three experiments were conducted using different combinations of chilling durations of 6, 12, 24, or 36 hours and chillin...

no sufficient of chilling is a major problem in producing temperate fruit in warm climates. so determination of chilling requirement of different cultivars of grape is important. the aim of this research was determination of chilling requirement of four grape vine commercial cultivars including: kolahdary, red rasin, yaghoti and white rasin that factorial experiment based on a completely random...

Seedlings of corn (Zea mays) were tested for recovery from chilling injury incurred at 0.3 +/- 0.3 C. At 0.3 C visual leaf injury appeared in 36 hours, whereas stem and root injuries appeared later. Appearance of leaf injury was preceded by a rise in O(2) uptake and a lessened effect of 2,4-dinitrophenol on O(2) uptake by leaf segments and was accompanied by increased ion leakage from the leave...
