Other claims from this paper (9)
- Intervention effect At 500 nematodes per kg soil, shoot dry weight of Bud 9 was significantly reduced by 30%.
- Intervention effect At 500 nematodes per kg soil, shoot dry weight of M.9 was significantly reduced by 23%.
- Intervention effect At 500 nematodes per kg soil, shoot dry weight of M.26 was significantly reduced by 14%.
- Intervention effect At 1500 nematodes per kg soil, root dry weight of M.26 was reduced by 26% relative to non-inoculated trees.
- Intervention effect Root dry weights of rootstocks, except M.26, were not significantly reduced by these P. penetrans densities.
- Intervention effect At 1500 nematodes per kg soil, shoot dry weight of M.26 decreased by 29%.
- Association M.26 may show some tolerance to P. penetrans at lower density compared with M.9 and Bud 9 (preliminary).
- Association At higher nematode densities, Bud 9 and M.9 showed greater root-system tolerance than M.26.
- Recommendation Further assessment of susceptibility and tolerance of dwarfing apple rootstocks to P. penetrans densities is needed.
