Fig. 1. Model of germination (%) of aeciospores from seven seed orchards (sv = 1–7) at temperatures between 6–30 °C after 24 h of incubation on water agar (agar = 1) and malt agar (agar = 2). Spore sources (sv = 1–7): Paronen (1), Metsä-Ihala (2), Imatra (3), Sillanpää (4), Suhola (5), Taavetti (6) and Riihimäki (7) seed orchards. View larger in new window/tab.

Fig. 3. Variation in germination of aeciospores (%) of seven spore sources at temperatures between 6–30 °C on water agar (agar = 1) and malt agar (agar = 2). The germination curves are presented separately after 2 h (1), 6 h (2) and 24 h (3) incubation. For the spore sources (sv 1–7), see Fig. 1. View larger in new window/tab.
