| Abstract: | Aeciospores of Endocronartium pini (Peridermium pini) and Cronartium flaccidum were analysed with regard to free amino acid content. As a rule the quantity in Endocronartium pini is greater than in Cronartium flaccidum. Twenty four amino acids were identified. Regarding thirteen amino acids, the quantity in Endocronartium was greater than in Cronartium; three amino acids were greater only in one year; two amino acids were about the same in the aeciospores of both species, and six occurred only in one analysis or as a trace. The beetle, Lagria hirta, has been observed to eat the acciospores of Endocronartium pini. |
