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...

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...

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...

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:: Moore, Georgianne W.
Abstract:: I compared transpiration among different types of forest stands in the western Cascades of Oregon. The three major questions were: 1) How does transpiration compare between a young and old stand and why? 2) Does diversity of overstory trees affect transpiration? and 3) How is transpiration related to stream flow?...

Creator:: Barnard, Holly Rene
Abstract:: The links between forests, streamflow, and climate are poorly understood. Despite hundreds of studies over the past 60 years, fundamental questions of forests' effects on the hydrologic cycle remain unanswered. The hydrological cycle involves mutually-dependent biological and physical processes that operate at multiple scales of time and space, and this...
