Geographical variation in apparent net photo-synthesis of Rocky Mountain Douglas-fir, Pseudotsuga menziesii var. glauca

Creator:

Pope, Walter William

Abstract:

Rates of apparent net photosynthesis were measured on a sample of Rocky Mountain Douglas-fir consisting of eleven one-year-old seedlings from each of the thirteen different seed sources. Secondary observations of needle length, needle weight, and needle number were also obtained. A formula derived through step-wise multiple regression of the secondary...

Geographic and seasonal variation in photosynthetic efficiency and capacity of Rocky Mountain Douglas-fir, Pseudotsuga menziesii var. glauca

Creator:

Pope, Walter William

Abstract:

Net photosynthesis was measured for photosynthetic light efficiency and capacity on two-year-old plants from eight different seed sources in three measurement periods. The measurement periods corresponded to the physiological periods 1) prior to bud swelling, 2) after needle elongation, and 3) predormancy. Measurement period differences in both photosynthetic efficiency and...
