Abstract
Dormant branches of Fraser fir [Abies fraseri (Pursh) Poir.] Christmas trees were subjected to single doses of gamma radiation at levels ran ging from 0 to 5.0 kGy (0 to 500 kRad). Significant needle loss result ed at doses greater-than-or-equal-to 0.10 kGv and increased with radia tion intensity. Irradiation discolored foliage and accelerated drying. Irradiation does not appear to be a viable way to meet insect quarant ine requirements on cut Fraser fir Christmas trees.
