Abstract
External needle extracts from an infected and a healthy Pinus sylvestris L. did not adversely affect the germination of aeciospores of Peridermium pini (Pers.) Lev.Internal extracts and juices expressed from needles and shoots showed a fungistatic effect on spores. The effect was more pronounced when extracts and juices were derived from needles of a healthy tree than from an infected one. In the former case, the germ tubes were invariably deformed. The significance of these differences in relation to resistance is discussed
