Effects of shade on performance and chlorophyll fluorescence of four Pacific Northwest seedling conifer species

Creator:

Khan, Shafiqur Rehman

Abstract:

The influence of shading intensity on performance, chlorophyll fluorescence emissions, the slope of the fluorescence induction curve, chlorophyll contents, and stomatal conductance of four Pacific Northwest conifer species [ponderosa pine (Pinus ponderosa Laws.), Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), western redcedar (Thujaplicata Donn.), and western hemlock (Tsuga heterophylla (Raf.) Sarg.)] was...

Effects of water stress on phenology, physiology, and morphology of containerized Douglas-fir (Psuedotsuga menziesii (mirb.) Franco) seedlings

Creator:

Khan, Shafiqur Rehman

Abstract:

Approximately 3-4 month-old containerized Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seedlings (seed zone 262 and 271) were subjected to 6 moisture stress treatments (65, 53, 41, 29, 17 and 7% soil water content by volume of dry soil) starting July 4 to September 22, 1991 at Forest Research Laboratory's greenhouse at...
