Cold injury and hardiness [PDF]

open access: yes, 2015
An examination of the relationship between cold tolerance, dormancy and hardiness in woody shrubs and trees of garden origin. The physiological, biochemical and genetic backgrounds to these characteristics are discussed using appropriate examples.

Molecular mechanisms of plant freezing tolerance: from cold signal perception to adaptive responses [PDF]

open access: yesFrontiers in Plant Science
Freezing stress poses a threat to plant survival and crop production; therefore, understanding the molecular basis of freezing tolerance and broader cold hardiness is essential for developing cold-hardy crop varieties.

Studies on the cold hardiness of the peach-potato aphid Myzus persicae (Sulzer) [PDF]

open access: yes, 1985
A system incorporating a prototype automatic thermoelectric cooling method with computer-based recording of aphid supercooling points was developed and formed the basis of cold hardiness assessment. Under laboratory culture all developmental stages of

Cold hardiness and overwintering survival of the grain aphid Sitobion avenae in Northern England [PDF]

open access: yes, 1987
Laboratory maintained Sitobion avenae of all developmental stages had a mean inherent supercooling ability below -20°C. Acclimation alone, or in conjunction with starvation had no significant effect on supercooling.

Seasonal variations of cold hardiness and dormancy depth in five temperate woody plants in China

open access: yesFrontiers in Forests and Global Change, 2022
Woody plant species in temperate regions must withstand a cold winter and freezing events through cold acclimation and dormancy in autumn and winter. However, how seasonal changes in dormancy depth and cold hardiness affect the frost risk of temperate ...

A Translocatable Cold Hardiness Promoter [PDF]

open access: yesPlant Physiology, 1971
Hardy woody species which cold acclimate late or slowly are often injured by early autumn frosts. Adapted hardy species characteristically stop growing and acclimate to some extent prior to autumn frosts. In nature this first stage of acclimation appears to be induced by shortening photoperiods in a number of woody species (4, 23, 24).

Hardiness, appraisal and coping; a qualitative study of high and low Hardy managers [PDF]

open access: yes, 2004
challenge, control and commitment. Hardiness is often referred to in the literature as a stress-resilience factor. Resilience is thought to result from superior coping and a more positive appraisal of potential stressors. Yet, despite the importance of
