Abstract: | Newly germinated seedlings of susceptible cultivars of oats, wheat, barley and rye were inoculated with second-stage juveniles of Heterodera avenae in pots of sand. Subsequent examination showed oat root tips to be more commonly invaded, and by a greater range of nematode numbers than the other cereals. A comparison of oats and barley showed that lower nematode numbers in barley were not due to a higher emigration from barley; invasion, establishment and emigration by nematodes all being greater in oats. Second-stage juveniles were more likely to migrate prior to establishment in barley than in oats. |
