Abstract
Drought and frosts are major determinants of plant functioning and distribution. Both stresses can cause xylem embolism and foliagedamage. The objective of this study was to analyse if the distribution of six common pine species along latitudinal and altitudinalgradients in Europe is related to their interspecific differences in frost tolerance and to the physiological mechanismsunderlying species-specific frost tolerance. We also evaluate if frost tolerance depends on plant water status. We studied survivalto a range of freezing temperatures in 2-year-old plants and assessed the percentage loss of hydraulic conductivity (PLC) duexylem embolism formation and foliage damage determined by needle electrolyte leakage (EL) after a single frost cycle to −15 °Cand over a range of predawn water potential (psipd) values.
