Abstract:: Xylem anatomy is a strong determinant of water transport efficiency and is therefore an important component of the overall hydraulic strategy of any woody plant. However, in addition to its role in water transport, xylem also serves in mechanical support, and these two functions may represent conflicting design requirements. To...

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...

Creator:: Woodruff, David R.
Abstract:: This dissertation investigated the impacts of tree height upon a range of physiological and structural characteristics of Douglas-fir foliage; relationships between structural and functional trends with height; and compensatory mechanisms that mitigate height-related growth constraints. Height-related trends in foliar physiological and anatomical characteristics were examined both within trees as well...

Creator:: Guak, Sunghee
Abstract:: Sorbitol-induced osmotic stress (SIOS) to the root was found to be effective in reducing transpirational water loss in plants during water stress. Mechanisms of SIOS in stomatal control were investigated in containerized apples (Malus domestica Borkh. 'Gala'/M26) when leaf water potential (Ψw), osmotic potential (Ψs), turgor potential (Ψp), stomatal conductance...

Creator:: Currans, Sean
Abstract:: Seed vigor tests have been developed to evaluate the relative ability of seed lots to produce stands of seedlings in the field. Some workers have suggested the possibility of differentiating vigor levels by germinating seeds under osmotic stress, but have not conducted field trials to evaluate the usefulness of the...
