Claim · model-written summary
Most difficult-to-infect (DI) full-sib families of western white pine had significantly lower disease assessment index scores than several other full-sib families selected for other partial resistance traits after inoculation with C. ribicola.

Other claims from this paper (4)
- Observation Most DI full-sib families of western white pine had significantly higher epicuticular wax content than the other full-sib families.
- Intervention effect When the wax was removed from the needle surface, the disease assessment index of all full-sib families increased.
- Observation Scanning electron microscopy showed that stomata in DI full-sib families are mostly occluded by epicuticular wax.
- Mechanism The authors suggest that the DI resistance mechanism of western white pine is related to needle surface epicuticular wax, which likely hinders penetration of stomata by fungal hyphae.
