Description: Previously, we demonstrated that wood chips, essential oil, and four individual compounds from Alaska yellow-cedar (Chamaecyparis nootkatensis [D. Don] Spach) heartwood strongly inhibit the germination f Phytophthora ramorum (Werres, de Cock, Man int Veld) zoospores or sporangia, and reduce hyphal growth in culture (Manter and others 2006). Essential oils from heartwood of incense cedar (Calocedrus decurrens [Torr.] Florin), western red cedar (Thuja plicata Donn ex D. Don), Port-Orford-cedar (Chamaecyparis lawsoniana [A. Murr.] Parl.), and western juniper (Juniperus occidentalis Hook.) were also tested and found to be equally active, but not investigated further until now. The objectives of this study were to: 1) test the procedure described by Kuhajek and others (2003) as a bioassay technique for P. ramorum; 2) use this bioassay with other individual compounds from yellow-cedar heartwood that were not previously tested for bioactivity toward P. ramorum; and 3) bioassay extracts and compounds from the heartwood of the other conifers with antimicrobial essential oils and compare their P. ramorum activity to the yellow-cedar constituents.

Keywords: Photometric bioassay, conifer heartwood, antimicrobial activity
