Title: Foliar essential oils and deer browsing preference of Douglas-fir genotypes

Author: Radwan, M.A.;

Date: 1978

Source: Res. Note PNW-RN-324. Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Forest and Range Experiment Station. 6 p.

Publication Series: Research Note (RN)

Description: Yield and composition of essential oils were compared in foliage of Douglas-fir. Five clones with different susceptibilities to deer browsing were used; foliage was collected during the dormant season. There were no qualitative differences among the oils of the different clones, but the oils differed quantitatively in all variables measured. Eight variables appeared useful in separating resistant from susceptible clones. Only one compound, however, an unidentified chemical, seemed capable of distinguishing between all three deer browsing preference classes.

Keywords: Essential oils chemistry, browse preference, genotypes, Douglas-fir, Pseudotsuga menziesii, deer, black-tailed
