Mexican lime is one of the commercial citrus cultivars in the world, which is commonly used as a citrus rootstock in the southern regions of Iran. This cultivar is one of the most sensitive citrus cultivars to cold stress and is used as a cold-sensitive plant in many citrus studies. This study aimed to investigate the effect of melatonin (0 and 500 μM), mannitol (0 and 50 μM), acetic acid (0 an...

As a typical warm-season grass, Bermudagrass [Cynodon dactylon (L).Pers.] is widely applied in turf systems and animal husbandry. However, cold temperature is a key factor limiting resource utilization for Bermudagrass. Therefore, it is relevant to study the mechanisms by which Burmudagrass responds to cold. Melatonin is a crucial animal and plant hormone that is responsible for plant abiotic s...

Heat shock protein synthesis can be induced during recovery from cold treatment of Drosophila melanogaster larvae. Survival of larvae after a cold treatment is dramatically improved by a mild heat shock just before the cold shock. The conditions which induce tolerance to cold are similar to those which confer tolerance to heat.

this study was conducted on two canola (brassica napus) cultivars, okapi a winter type and cold tolerant and rgs003 a spring type and cold sensitive. seedlings were grown in an environmentally controlled growth room with 16 h d-1 photoperiod at 22/16 °c (day/night, control). at the 4-leaf stage, half of pots were transferred to a cold growth room for 7 d at 10/3°c (day/night, cold treatment) an...

the process of adaptation to cold is an important mechanism in wheat cultivars to tolerate cold stress. this work was aimed to calrify the relationship between vernalization requirement with cold tolerance by assessing physiological changes in cold susceptible spring and tolerant winter wheat (triticum aestivum, cvs. kohdasht and cheyyene, respectively) in environmentally controlled conditions,...
