silver fir - Opis:
- Preliminary studies on frost−hardiness of the current year shoots of silver fir were conducted between the autumn of 1999 and the spring of 2000 on the 20−25 year old saplings, collected in 13 sample plots distributed throughout the Świętokrzyski National Park.The diffusion of electrolytes from shoots and needles kept in a freezer at the temperature of −33°C was analysed using the Dexter's (1932) method. The highest degree of frost−hardiness of shoots and needles was found in February. In spring the resistance to low temperatures declined faster in shoots than in needles.The investigations showed significant differences in the frost−hardiness of young silver firs from different sample plots.
