Physiological and biochemical studies of stratified Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] seeds after redrying, storage, and subsequent germination

Creator:

Malavasi, Marlene de Matos

Abstract:

The physiological and biochemical responses of Douglas-fir seeds to stratification, redrying, storage and subsequent germination were determined. Stratification increased seed vigor, embryo and gametophyte phosphorylative efficiency and RNA synthetic ability. Redrying seems to increase the rate of enthryonic nucleic acid synthesis, speed of germination and seedling vigor. ATP, total adenosine...

Energy exchange of transplanted Douglas-fir seedlings on two cutover sites in southwestern Oregon

Creator:

Vanderwaal, James A.

Abstract:

An energy balance analysis was performed on each of four transplanted Douglas-fir [Pseudotsuga menziesii (Mirb.) Francol seedlings growing on two cutover sites in southwestern Oregon. The two sites were a clearcut and a partial-cut (shelterwood) side by side, with a pair of seedlings used on each site. One seedling of...
