The transpiration process as a function of environmental parameters

Creator:: Cox, Lloyd Morris
Abstract:: The influence of soil moisture stress and soil temperature on transpiration has never been determined explicitly. This relationship has been neglected mainly because of the lack of a satisfactory method to control soil moisture stress. A technique was developed to evaluate this relationship by controlling soil moisture stress with osmotic...

Dynamic simulation model of transpiration process with stomatal control mechanism

Creator:: Woo, Kwang Bang
Abstract:: Because the life processes of the plant are related in a complex way to the balance between the water demand of the atmosphere and the water availability to the plant root, an exploration of the dynamic status of water in the plant is very important. The stomata constitute the main...

Leaf resistance responses in selected conifers interpreted with a model simulating transpiration

Creator:: Running, Steven William
Abstract:: The resistance of a leaf to molecular gaseous diffusion is an important physiological response. Control of leaf resistance enables a plant to control its transpired water loss and regulates photosynthesis. Four study sites representing a gradient in available moisture and evaporative demand, were chosen in western Oregon for the study...

A computer simulation model of seasonal transpiration in Douglas-fir based on a model of stomatal resistance

Creator:: Reed, Kenneth Lee, 1942-
Abstract:: Four study sites were selected along an altitudinal gradient on Mt. Ashland in the Siskiyou Mountains of southern Oregon. The altitudinal gradient roughly corresponded to a gradient in temperature and water availability ranging from very hot and dry to cool and moist. Air and soil temperatures were continuously measured on...

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....

Water relations, stomatal conductance, and abscisic acid content of container-grown apple (Malus domestica Borkh.) plants in response to sorbitol-induced osmotic stress

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...

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

Creator:: Geppert, Rollin Roger
Abstract:: The objective of this study was to determine the effect of age on rates of transpiration by Douglas-fir seedlings. Seeds were collected from a xeric site (Goldendale, Washington) and a mesic site (Forks, Washington). The seedlings were grown in a cold frame and in a growth chamber for periods of...
