Chilling at 4 degrees C in the dark induced lipid degradation in cucumber (Cucumis sativa L.) fruit upon rewarming at 14 degrees C. Rates of ethane evolution by fruits rewarmed after 3 days of chilling were up to four-fold higher than those evolved by unchilled (14 degrees C) fruits (0.02-0.05 picomoles gram fresh weight(-1) hour(-1)). This potentiation of lipid peroxidation occurred prior to i...

soilless culture systems of strawberry production are increasing. yield and fruit quality are not only affected by growing media but also by chilling and horticultural managements. the aim of this study was to evaluate the effect of different growing media and chilling on vegetative growth, yield and fruit quality of three strawberry cultivars. the experiment was conducted in factorial experime...

Exposure to a chilling temperature of 2.5 degrees C for 96 h inhibited the subsequent growth of cucumber seedling radicles at 25 degrees C by 92%. Exposing seedling with 5 +/- 1 mm long radicles to acetaldehyde vapour (275 micro l l(-1)) or to an aqueous ethanol solution (0.6 M) for 2 h, or to 45 degrees C for 10 min before chilling, increased chilling tolerance so that the chilling treatment r...

Chilling at 2.5 C accelerated the synthesis of 1-aminocyclopropane-1-carboxylic acid (ACC) and C(2)H(4) production in cucumber fruit. Skin tissue contained higher levels of ACC and was more sensitive to chilling than was cortex tissue. Accumulation of ACC in chilled tissue was detected after 1 day of chilling and remained elevated even after C(2)H(4) production started to decline. These data su...

Microbiological sampling of processed broiler carcasses often relies on the technique of whole-carcass rinsing; however, the rinse sampling is sometimes done immediately after immersion chilling and sometimes as long as 24 h after immersion chilling. To test whether carcass rinses done immediately after chilling can be compared with rinses 24 h after chilling, 20 whole broiler carcasses exiting...

Susceptibility to chilling injury prevents the cultivation of many important crops and limits the extended storage of horticultural commodities. Although freezing tolerance is acquired through cold-induced gene expression changes mediated in part by the CBF family of transcriptional activators, whether plant chilling resistance or sensitivity involves the CBF genes is not known. We report here ...

Accumulation of γ -aminobutyric acid (GABA) is associated with stress factors in plant systems. The objective of the current study was to compare GABA concentration in wheat plants under chilling stress. After 48 h treatments of seedlings under chilling stress combined stresses with and without GABA, morphological and biochemical assays were conducted. It was observed that the inhibition of see...

In this study, the effects of climate change on irrigation water requirement hazelnut trees were investigated in Central Italy. The meteorological variables considered precipitation, temperature, chilling units, and Standardized Precipitation Index (SPI) hydrological reference evapotranspiration (ET0) based soil balance. Climate data collected from eight stations for period 1974–2021, ET0 was e...

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...
