Creator:: McCreary, Douglas D.
Abstract:: The physiological condition of tree seedlings at the time they are planted can have a profound impact on their subsequent field performance. Damaged or low vigor seedlings have a much greater chance of dying in the field, or at best, of growing slowly during their initial establishment period. Several methods...

Creator:: Forry, Keith R.
Abstract:: The goal of this study was to evaluate the ability of two seedling quality evaluation methods to predict the field survival of Douglas-fir (Pseudotsuga menziesii) seedlings. The starch reserves in seedlings have been suggested as a possible predictor of seedling quality. Starch reserves have been shown to decrease during cold...

Full Text:: seedling quality evaluation methods to predict the field survival of Douglas-fir (Pseudotsuga menziesii

Creator:: Hipkins, Valerie D.
Abstract:: The physiological condition of a seedling often determines its ability to survive when planted. However, physiological damage is difficult to determine from external measurement or observation, because a healthy looking seedling can be of poor quality (quality is defined as the ability of a seedling to survive when outplanted). Methods...

Creator:: Schuch, Ursula K.
Abstract:: Two-year-old Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] seedlings of two seed sources raised in three nurseries in Oregon and Washington were tested for differences in frost hardiness from September 1985 to March 1986. The objective of the study was to determine whether nursery location had an influence on seedling acclimation, deacclimation...

Creator:: Graff, Joseph Edward
Abstract:: Western redcedar, western hemlock, and Douglas-fir seedlings were transplanted into pots in one of two soils representative of high and low levels of available NO3 (and total N). The soils were collected from sites at Cascade Head (Oregon Coast) and Wind River (Washington Cascades). Whole plant and component relative dry...
