Spacing effects and seed-lot contrasts in field-expressed foliar necrosis, survival, and growth of Eucalyptus nitens in a Nelder genetic trial under Atlantic sanitary conditions

open access: yesFrontiers in Forests and Global Change
IntroductionGenetic trials can provide comparative evidence on host performance under shared field exposure that is relevant to forest health surveillance, yet field evidence linking early foliar damage, spacing, and later plantation performance remains ...
