Abstract

Cysts, extracted from soil, of Heterodera avenae, pathotype Ha11, were stored at + 20, + 2, and -18 degrees C, with or without CaCl2, as a drying agent. Freeze-dried cysts (- 60 degrees C for 5 h 30 min) were stored at -18 degrees C, and unextracted cysts in soil were stored at 2 degrees C as controls. After 6, 12, 18, 24, and 60 months, cysts were transferred into hatching conditions at + 12 degrees C, and the emergence of juveniles was observed for 26 weeks. The best juvenile emergence was obtained from cysts kept at + 2 degrees C in the soil for 6 months. At longer storage of inocula, the highest relative juvenile emergence was obtained for freeze-dried cysts stored at - 18 degrees C. In these conditions, a higher proportion of cysts with at least one emerging juvenile was recorded.
