Physiological and anatomical studies of several groups of Douglas-fir (pseudotsuga menziesii (Mirb.) Franco) seedlings which demonstrated differential survival potential under drought stress

Creator:

Heiner, Terry Charles, 1941-

Abstract:

Several hundred two year old Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seedlings were planted in an enclosure designed to permit control of soil moisture. The seedlings came from five seed sources in southern Oregon and one seed source in northwestern Oregon. Mortality terminal and lateral budburst, and soil moisture were recorded...

Creator:

Heiner, Terry Charles, 1941-, Lavender, Denis P., and Oregon State University. Forest Research Laboratory

Abstract:

Although the Douglas-fir region of the northwestern United States and British Columbia is frequently considered to have a common silviculture, obstacles to successful regeneration of the species range from competing vegetation and mammals on the mesic sites to extreme drought and heat on the xeric southerly exposures in northern California...
