Abstract: Genetic variation in drought hardiness traits and their genetic correlations with growth potential and17re1c6overy
traits were investigated in 39 full-sib families of coastal Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb.)
Franco) from southwestern British Columbia. Seedlings of these families were grown in raised nursery beds and subjected
to three moisture...
Variation in cold-hardiness traits, and their extent of genetic control and interrelationships, were investigated
among individuals (clones) within a single large full-sib family of coastal Douglas-fir (Pseudotsuga menziesii var.
menziesii (Mirb.) Franco) from Oregon. Cold injury to needle, stem, and bud tissues was evaluated in fall 1996 and
spring 1997...
