Abstract
Scots pine seedlings were grown in quartz sand and were given N and K in different ratios with irrigation water. Fifty percent of the seedlings were inoculated with a conidial suspension ofAsoocalyx abietina (Lagerb.) Schlaepfer-Bernhard. The amount of damage caused by the pathogen was surveyed by measuring the specific symptoms on each seedling. The results suggest that an increased availability of N increases the degree of scleroderris canker damage in Scots pine seedlings. The possible connection between N-fertilization, deposition of N containing compounds in forests and the abundance of the disease is discussed.
