Growth phenology (i.e., timing of growth initiation and cessation) is important to adaptation. This study examined the extent of genetic control of bud and cambial phenology and their relationships with stem
growth in pole-size Douglas-fir (ages 13 to 16 years) from 60 open-pollinated families. The availability of bud phenology data...
One hundred and four seed sources from throughout the range of Douglas-fir (Pseudotecia menzieaii (Plirb.) Franco)
were analysed at 20 enzyme loci to determine patterns of genetic variation and to examine intraspecific phylogeny. On average the seed sources were polymorphic at 37 percent
of the loci (range 5.0-65.0), with mean...
