seeds of most herbs such as medicinal plant alyssum bracteatum are known to have a dormancy period in a natural condition. therefore, the identification of factors affecting seed dormancy and germination in order to create optimum conditions for large-scale cultivation of medicinal plants is necessary. the survey was conducted at the research laboratory of biology, university of lorestan in aut...

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...

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 ...

In trees adapted to cold climates, conditions during autumn and winter may influence the subsequent timing of bud burst and hence tree survival during early spring frosts. We tested the effects of two temperatures during dormancy induction and mild spells (MS) during chilling on the timing of bud burst in three Picea abies (L.) Karst. provenances (58-66 degrees N). One-year-old seedlings were i...

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...

Chilling stress is a major factor limiting plant development and crop productivity. Because the plant response to chilling is so complex, we are far from understanding the genes important in the response to chilling. To identify new genes important in chilling tolerance, we conducted a novel mutant screen, combining a confirmed SALK T-DNA insertion collection with traditional forward genetics. ...

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...

Using the chilling effect research as a framework, the purpose of this study was to examine the relationship of binge drinking to the suppression of grievances in both romantic and close platonic relationships (N = 317). Results demonstrated the association between binge drinking and chilling effects, although this relationship was only evident in friendships. Overall, chilling effects were fou...

Flowering time is a decisive factor in the adaptation of oat to sub-tropical environments. Varieties grown in southern Brazil show varying response to low temperature-dependant floral initiation, a process called vernalization. Vernalization is defined as “the acquisition or acceleration of the ability to flower by a chilling treatment” (Chouard 1960). Genetic analyses have identified at least ...

Chilling injury in tropical and subtropical fruits can be alleviated by low temperature preconditioning, intermittent warming, heat treatment, controlled atmosphere storage, treatments with calcium or other chemicals, waxing, film packaging, genetic modification, or applications with ethylene, abscisic acid, polyamines, methyl jasmonate, methyl salicylate, or other natural compounds. The effect...
