The effect of plant moisture stress on the physiology and establishment of planted Douglas-fir and ponderosa pine seedlings

Creator:

Cleary, Brian D.

Abstract:

The role of moisture stress in seedling physiology and establishment was studied in both the field environment and laboratory experiments. Plant moisture stress was measured using the pressure chamber technique. This technique was modified and tested using a fascicle of pine needles as a sample, an improvement which allows the...

Seasonal and diurnal variation in internal moisture stress of mature Douglas-fir

Creator:

Cleary, Brian D.

Abstract:

The internal moisture stress of Douglas-fir was determined on foliage collected in the Siskiyou Mountains of southwestern Oregon. Internal moisture stress integrates both climatic and edaphic environmental effects as they influence a plants moisture regime. In this study two laboratory techniques were modified to permit stress measurements to be taken...
