Genetic variation in drought hardiness of coastal Douglas-fir seedlings from British Columbia

Creator:

Anekonda, T. S., Lomas, M. Christine, Adams, W. T., Kavanagh, Kathleen L., 1955-, and Aitken, S. N.

Abstract:

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...

Within-stem variation of respiration in Pseudotsuga menziesii (Douglas-fir) trees

Creator:

Pruyn, Michele L., Gartner, Barbara L., and Harmon, Mark E.

Abstract:

• A technique for measuring in vitro respiration was investigated to understand why rates were higher than those reported in vivo and to elucidate trends within mature Pseudotsuga menziesii (Douglas‐fir) trees. • Extracted increment cores were divided into 3–4 radial depths and a gas chromatograph was used to compare respiration...
