Frost resistance in alpine woody plants
This report provides a brief review of key findings related to frost resistance in alpine woody plant species, summarizes data on their frost resistance, highlights the importance of freeze avoidance mechanisms, and indicates areas of future research. Freezing temperatures are possible throughout the whole growing period in the alpine life zone. Frost severity, comprised of both intensity and d...
متن کاملBacterial ice nucleation: a factor in frost injury to plants.
Heterogeneous ice nuclei are necessary, and the common epiphytic ice nucleation active (INA) bacteria Pseudomonas syringae van Hall and Erwinia herbicola (Löhnis) Dye are sufficient to incite frost injury to sensitive plants at -5 degrees C. The ice nucleation activity of the bacteria occurs at the same temperatures at which frost injury to sensitive plants occurs in nature. Bacterial ice nucle...
متن کاملFrost heave
The deformation of the ground surface that is produced by frost heave has motivated almost a century of concerted laboratory, field and theoretical studies. Well before the development of equipment capable of resolving the microscopic films that support liquid transport towards growing ice lenses, early investigators predicted their occurrence and noted their importance. Idealized experiments c...
متن کاملUremic frost
Full blown uremic syndrome of chronic kidney disease (CKD) is seldom seen these days due to early initiation of renal replacement therapies (RRT) [1, 2]. Uremic frost is a manifestation of advanced CKD but rarely seen due to effective RRT. We came across a 21-year-old male patient, brought to us with complaints of nausea, anorexia, oliguria and recent onset alteration in sensorium. On physical ...
