| Sumario: | Hatching tests with,Spanish populations of Heterodera avenae using cysts in distilled water kept in soil at 15 cm depth, showed juvenile emergence beginning in the autumn at 15-20°C, without needing a cold stimulus. Maximum emergence coincided with temperatures of 5;10.5°C and emergence stopped in spring as temperature approached 15°C. Percentage of emergence was about 90-100% far 8-17% of the individuals, and >60% for 14-28% of them. |
