The effect of internal and external moisture stress on the transpiration rate of Douglas-fir seedlings (Pseudotsuga menziesii (Mirb.) Franco)

Creator:

Unterschuetz, Phillip

Abstract:

The objective of this study was to examine the transpirational behavior of Douglas-fir seedlings from two origins,, each grown in two environments, and subject to a range of moisture stress. Forks and Goldendale, Washington were the mesic and xeric seed origins respectively. One-half of the seedlings from each origin was...

The effect of seed source on transpiration rates of seedlings of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco)

Creator:

Ruetz, Wolfhard Friedrich

Abstract:

In this study transpiration rates were measured on Douglas-fir seedlings from five seed sources. The seedlings were grown under two environments, a growth chamber and outside in cold frames. Transpiration was measured at two ages, 4 and 16 weeks. Comparison of transpiration rates was made at low soil moisture stress....
