The effect of drought on the rate of photosynthesis, respiration, and transpiration in two ecotypes of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco)

Creator:: Zavitkovski, J.
Abstract:: The subject of this study was the determination of the changes in photosynthesis, respiration and transpiration in two ecotypes of Douglas-fir as caused by decreasing soil moisture content. The photosynthetic rate was also correlated with the relative turgidities of needles. All the above processes were greatly affected by decreasing soil...

The effect of osmotic moisture stress during germination on Douglas-fir (Pseudotsuga menziesii)

Creator:: Stewart, Ronald E
Abstract:: Commercially collected Douglas-fir seed from a moist coastal ecotype (LaPush, Washington) and a dry inland ecotype (Kaibab National Forest, Arizona) were subjected to osmotic stresses ranging from 0 to -8 atmospheres using Carbowax polyethylene glycol 6000 during imbibition and germination. To determine the effect of osmotic stress on the initiation...

Some physiological effects of atrazine on Douglas-fir seedlings

Creator:: Peterson, Charles Adrian
Abstract:: This study was undertaken to ascertain some of the physiological effects of the herbicide atrazine on Douglas-fir seedlings. Photosynthetic and respirational rates were measured on seedlings grown in a controlled environment chamber. Height and dry weight increases, shoot/root ratios and percent total nitrogen were obtained from treated and control seedlings...

The biologies of two dipterous predators of Dendroctonus pseudotsugae Hopkins (Coleoptera : Scolytdae) in western Oregon and Washington

Creator:: Johnsey, Richard Lee
Abstract:: The objectives of this study were: 1) to learn the life history and habits of Medetera aldrichii Wheeler and a Lonchaea sp. in association with the Douglas-fir beetle, Dendroctonus pseudotsugae Hopkins, in western Oregon and Washington; 2) to determine if the larvae of M. aldrichii were predaceous on the Douglas-fir...
