Two-year, bare-rooted seedlings of Norway spruce (Picea abies [L.] Karst.) were used in this study. The seedlings were exposed to artificial desiccation and frost stress after spring lifting. After exposure to these factors, electrolyte leakage from the root system was measured. The results showed that artificial desiccation significantly affected the rate of electrolyte leakage. The effect of desiccation was confirmed by the survival of plants and height increment (100% survival and 49% height increment of control seedlings in contrast with plants after 6 hours of desiccation: 9% survival and 2% height increment). On the other hand, frost stress did not affect the rate of electrolyte leakage (the rate of REL did not correlate with the intensity of stress treatment).
