Water Relations, Stomatal Behavior, and Root Conductivity of Red Osier Dogwood during Acclimation to Freezing Temperatures.
Red osier dogwood (Cornus stolonifera Michx.) was artificially acclimated by exposing plants to 8-hour short days (SD) and low (15/5 C) temperatures for 54 to 63 days. Several factors including transpiration rate, stomatal resistance, and root conductivity were correlated so that the rate of water loss in acclimating plants was higher during the first 30 to 40 days of the acclimation sequence. ...

15 صفحه اولCharacterization of Water Channels in Wheat Root Membrane Vesicles.
The functional significance of water channels in wheat (Triticum aestivum L.) root membranes was assessed using light scattering to measure vesicle shrinking in response to osmotic gradients rapidly imposed in a stopped flow apparatus. Vesicles were obtained from both a plasma membrane fraction and a plasma membrane-depleted endomembrane fraction including tonoplast vesicles. Osmotic water perm...
متن کاملSquare-root relations between main saccadic parameters.
PURPOSE To derive and evaluate two equations in which saccade duration and peak velocity are proportional to the square root of saccade amplitude. METHODS A population of horizontal visually guided saccades in a range of amplitudes from 1.5 degrees to 30 degrees was recorded by means of electro-oculography in eight normal adult subjects. The peak velocity-amplitude data of this population wer...
متن کاملSquare-Root Relations Between Main Saccadic Parameters
Methods. A population of horizontal visually guided saccades in a range of amplitudes from 1.5° to 30° was recorded by means of electro-oculography in eight normal adult subjects. The peak velocity-amplitude data of this population were fitted to four models: inverse linear, exponential, power law, and square root. To approximate the duration-amplitude relation, the square root was tested again...
