Symbiotic nitrogen fixation is sensitive to dark chilling (7 degrees C-15 degrees C)-induced inhibition in soybean (Glycine max). To characterize the mechanisms that cause the stress-induced loss of nodule function, we examined nodule structure, carbon-nitrogen interactions, and respiration in two soybean genotypes that differ in chilling sensitivity: PAN809 (PAN), which is chilling sensitive, ...

1-Aminocyclopropane-1-carboxylic acid (ACC) level, ACC synthase activity, and ethylene production in cucumbers (Cucumis sativus L.) remain low while the fruit are held at a temperature which causes chilling injury (2.5 degrees C) and increase rapidly only upon transfer to warmer temperatures. The increase in ACC synthase activity during the warming period is inhibited by cycloheximide but not c...

The effect of chilling on translocation in higher plants was reviewed by separate consideration of path, sink, and source-cooling effects. The response of the sink to chilling indicates that the effect is mainly due to the inhibition of a metabolic process, while the response of the path to chilling suggests that the effect is mainly due to physical damage such as alteration of membranes. Sugar...

Peach and nectarine (Prunus persica L) are highly perishable; they ripen and deteriorate quickly at ambient temperature. Storage at low temperature (0–5oC) is a common strategy used to slow the ripening processes and extending shelf life. However, if susceptible varieties are held too long at a low temperature, they will not ripen properly and will develop chilling injury (CI) symptoms like mea...

The use of cold treatments to kill the rice weevil, Sitophilus oryzae (L.), before eclosionbut allow theparasitoidAnisopteromalus calandrae (Howard) tocompletedevelopment and eclosion was examined. Cold tolerance, crystallization temperature, and developmental stage of rice weevilswere examined at 2-d intervals between 18 and 30d after riceweevil oviposition. Themedian crystallization temperatu...
