Having analysed literary sources and own data, the authors have presumed that cold resistance in plants is formed by different mechanisms depending on the patterns of temperature effects in the diurnal cycle: the "periodic" one, caused by low-temperature drops over many days and the "nonperiodic" one, manifest at a continual action of low temperatures over many days. Drawing upon this hypothesis, as well as upon the assumption that continual (24 hour) action of the low temperature is the limit case of short-term (lasting 2 to 8 hours) temperature impacts within the diurnal cycle, two cold-resistance components were singled out through mathematical modeling. Regression models were built for relationships between cold-resistance values and different diurnal patterns of the low-temperature impact.
