Light response of hydraulic conductance in bur oak (Quercus macrocarpa) leaves.
A four- to seven-fold enhancement of leaf hydraulic conductance by light has been reported in three temperate tree species. The enhancement occurs in the liquid-flow pathway between the petiole and… Expand
Aquaporin gene expression and apoplastic water flow in bur oak (Quercus macrocarpa) leaves in relation to the light response of leaf hydraulic conductance
It has previously been shown that hydraulic conductance in bur oak leaves (Quercus macrocarpa Michx.), measured with the high pressure flow meter technique (HPFM), can significantly increase within… Expand
Inhibitor studies of leaf lamina hydraulic conductance in trembling aspen (Populus tremuloides Michx.) leaves.
The present study investigated leaf water transport properties in trembling aspen (Populus tremuloides) leaves. Leaf lamina hydraulic conductance (K(lam)) and stomatal conductance (g(s)) were… Expand
Responses of ectomycorrhizal American elm (Ulmusamericana) seedlings to salinity and soil compaction
American elm (Ulmus americana) seedlings were either non-inoculated or inoculated with Hebeloma crustuliniforme, Laccaria bicolor and a mixture of the two fungi to study the effects of… Expand
Diurnal and seasonal changes of leaf lamina hydraulic conductance in bur oak (Quercus macrocarpa) and trembling aspen (Populus tremuloides)
The aim of this study was to examine the diurnal and seasonal variations in the sensitivity of leaf lamina (Klam) hydraulic conductance to irradiance in bur oak (Quercus macrocarpa Michx.) and… Expand
Cycloheximide inhibits root water flow and stomatal conductance in aspen (Populus tremuloides) seedlings
Aspen (Populus tremuloides Michx.) roots were treated with cycloheximide, a protein synthesis inhibitor, to examine the role of protein synthesis in root water transport and plant water relations.… Expand
Le regard reciproque ou l'(im)possible connaissance de l'autre. À propos de la quatrième croisade
- M. Voicu
L’autre apparait opaque a l’homme medieval. Si tout chretien doit « aimer son prochain comme soi-meme », ce commandement nouveau ne s’applique qu’a l’interieur de la Chretiente. Le paien reste… Expand
Les « voies aventureuses » des études de littérature française médiévale en Roumanie
Nous nous proposons dans ce qui suit de poser quelques reperes du parcours des etudes medievales francaises en Roumanie. Pour qu’une periode, un courant litteraire, puisse susciter de l’interet, il… Expand
Combined use of GnRH analog and antagonist: redundancy vs. complementary action
POSITIONING CONTROL OF TRANSLATION MODULE USING INCREMENTAL TRANSDUCERS
The scope of the present paper is the presentation of a possibility to positioning control of a translation module using to this purpose incremental transducers, PC LPT Port Interface Circuit, a PC, and a software application written in Turbo Pascal program. Expand
