Abstract

Preliminary studies on frost-hardiness of the current year shoots silver fir were conducted between the autumn of 2000 and the spring of 2001 on the 20-30 year old saplings, collected in 5 sample plots distributed throughout the Beskid Śląski Mts. The diffusion of electrolytes from shorts and needles kept in a freezer at the temperature of -25º and -33ºC was analysed using the Dexter's method. The investigations showed essential differences in frost-hardiness of young silver firs from different sample plots. The investigations have shown, that in this region the meteorological conditions similar to those recorded in the year 2000 can occur quite frequently, leading to the second flushing in silver fir. The delay in the October 2000 adversely affected the process of frost-hardening in silver fir, which increased the risk of frost injuries in harsh winter conditions.
