frost tolerance of winter wheat depends primarily on a strong vernalization requirement, delaying the transition to reproductive phase. the responses of four bread wheat cultivars (triticum aestivum l.) to low-temperatures were examined in controlled environment and field conditions. prolonged cold treatment accelerated the transition to reproductive development in winter wheats (cv. norstar an...

cold tolerance is an adaptative mechanism that plants in temperate climates require to survive and grow in suboptimal temperatures.  exposed plant to low temperature produces a myriad of measurable changes in biochemical characters that are often highly correlated with plant cold tolerance.  a key element of cereal adaptation to cold is represented by the capacity for physiological adjustments ...

abstract: since sugar consumption is directly related to diabetes and other illnesses such as obesity, the issue that will most heavily dominate the health food market is blood sugar management and low glycemic foods. using calcium chloride and gums such as sodium alginate and low ester pectin as thikener and a high-potency sweetener aspartame we were able to reduce sugar content of sour cherry...

Changes in water content and dry weight were determined in control cells and those induced to cold harden in response to abscisic acid (ABA) treatment (7.5 x 10-5 molar). Bromegrass (Bromus inermis Leyss cv Manchar) cells grown in suspension culture at room temperature (230C) for 7 days acclimated to -28°C (LT50) when treated with ABA, or to -50C when untreated. ABA significantly reduced cell g...

Cold acclimation caused the following changes in the brown adipose tissue (BAT) of the hamster: the relative weight of the tissue increased, it color darkened, the multilocular structure predominated, and tissue protein content increased while fat content decreased. There was also an increase in the mitochondrial protein content. Heat acclimation had the opposite effects, i.e., the color became...

run-out-table (rot) is located between last finishing stand and down coiler in a hot strip mill. as the hot steel strip passes from rot, water jets impact on it from top and bottom and strip temperature decreases approximately from 800-950 °c to 500-750°c. the temperature history that strip experience while passing through rot affects significantly the metallurgical and mechanical properties, s...
