Title: Resin duct size and density as ecophysiological traits in fire scars of Pseudotsuga menziesii and Larix occidentalis

Author: Arbellay, Estelle; Stoffel, Markus; Sutherland, Elaine K.; Smith, Kevin T.; Falk, Donald A.;

Date: 2014

Source: Annals of Botany. 114(5): 973-980.

Publication Series: Scientific Journal (JRNL)

Description: Resin ducts (RDs) are features present in most conifer species as defence structures against pests and pathogens; however, little is known about RD expression in trees following fire injury. This study investigates changes in RD size and density in fire scars of Douglas fir (Pseudotsuga menziesii) and western larch (Larix occidentalis) as a means to evaluate the ecophysiological significance of traumatic resinosis for tree defence and survival.

Keywords: ecophysiology, conifer, fire scar, Larix occidentalis, western larch, Pseudotsuga menziesii, Douglas fir, resin duct, tree defence, wood anatomy
