Sažetak
After a severe outbreak of cold air in mid and late April in 1997, locally occurring damages on twigs and needles of silver fir were recorded in some forests in Croatia. Field examinations during the first half of May recorded the damages on one-year and older needles while fully developed twigs of current year growth were left intact. Southern and western slopes with fir growing forests represented typically affected sites. Further laboratory analysis confirmed the field observation that no harmful insect or pathogen were the cause of these damages. Spread of symptoms, expressed more heavily at lower elevations, indicated a probable connection with recent exceptionally cold air outbreak in mid-April. This exceptional event became a matter of later meteorological research. Physiological disturbances caused by potassium deficiency are discussed in the light of specific occurrences of damage symptoms on silver fir trees.
