The path to dormancy induction, maintenance, and release is a continuum and has been the topic of thousands of research articles to date. It would be an impossible task and indeed presumptuous of us to imagine that we could review all the research conducted on dormancy in the past century in this article. The multiple and complex nature of the dormancy phenomenon would require not one review bu...

Rice is sensitive to chilling stress, especially at the seedling stage. To elucidate the molecular genetic mechanisms of chilling tolerance in rice, comprehensive gene expressions of two rice genotypes (chilling-tolerant LTH and chilling-sensitive IR29) with contrasting responses to chilling stress were comparatively analyzed. Results revealed a differential constitutive gene expression prior t...

The adaptation of temperate fruit crops is a challenge being increased by the global warming. Chilling requirement key factor for adaptation. objective this study was to estimate chilling peach cultivars BRS Bonão, Esmeralda, Granada and Eragil, using Tabuenca test. accumulation computed four different hour (≤ 7.2 ºC ≤ 11 ºC) models; chill units Low Chill model Taiwan model. fresh bud weight wa...

Expression of selected genes in needles of Norway spruce (Picea abies [L.] Karst) was investigated by following their transcription levels during late autumn. Transcription was assessed in mature needles which likely serve as sensor of environmental cues that enable trees in the temperate and boreal regions to change between stages of growth, frost tolerance and bud dormancy. Samples were colle...

Chilling reduces the number of Campylobacter on pork meat. The humidity during chilling is expected to have an influence on the reduction of Campylobacter. In this study, bellies taken from carcasses before chilling have been inoculated either with a mixture of C. jejuni isolates or C.coli isolates and chilled with blast chilling or conventional chilling combined with two levels of relative hum...

Chilling effects on respiration during the recovery period were studied in two maize (Zea mays L.) cultivars differing in their tolerance to chilling: Penjalinan, a chilling-sensitive cultivar, and Z7, a chilling-tolerant cultivar. Both cultivars were exposed to 5 degrees C for 5 d, after which measurements were taken at 25 degrees C. Chlorophyll fluorescence analysis in dark-adapted leaves sho...

The effects of chilling on the photosynthesis of a chilling-resistant species, pea (Pisum sativum L. cv Alaska) and a chilling-sensitive species, cucumber (Cucumis sativus L. cv Ashley) were compared in order to determine the differences in the photosynthetic chilling sensitivity of these two species. For these experiments, plants were chilled (5 degrees C) for different lengths of time in the ...

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...
