Root tips of intact willow (Salix dasyclados Wimm., Clone 81-090) plants were partially dried by exposure to ambient greenhouse air and then kept in water-vapor-saturated air for up to 3 days. The drying treatment increased abscisic acid (ABA) concen

The effects of nitrogen deprivation on leaf extension, cell numbers and epidermal cell size were followed in leaves of Ricinus communis L. The extent to which reductions in final cell number or final epidermal cell size contributed to the reduction i

Small birch plants were grown for up to 80 d in a climate chamber at varied relative addition rates of nitrogen in culture solution, and at ambient (350 μmol mol-1) or elevated (700 μmol mol-1) concentrations of CO2. The relative addition rate of n

The influence of nitrogen on leaf area development and the biophysics of leaf growth was studied using clonal plants of the shrub willow, Salix viminalis grown with either optimal (High N) or sub-optimal (Low N) supplies of nitrate. Leaf growth rate

The use of three techniques for determining yield turgor in excised Salix leaves was investigated. These were the osmotic-solutions technique, the psychrometer technique, and the pressure-chamber technique. The application of the osmotic-solutions te

Excised leaves and roots of willow (Salix dasyclados Wimm.) accumulated abscisic acid (ABA) in response to desiccation. The accumulation of ABA was greater in young leaves and roots than in old leaves and roots. In mature leaves, ABA accumulation was

To investigate how nitrogen supply might affect the biophysical factors controlling diurnal variation in leaf extension, pot-grown Salix viminalis L. were supplied with nitrogen at a low relative addition rate of 0.05 g N g(-1) N day(-1) (low N) or w

Diurnal variations in leaf extension and turgor relaxation were measured in young willow leaves (Salix viminalis L.). Turgor relaxation was calculated from measurements of xylem water potential and osmotic potential of whole, detached leaves that wer

Diurnal variation in leaf extension and biophysical parameters of leaf growth were measured in young leaves from a stand of Salix viminalis L. in southern Sweden over a two-day period of clear skies during late July. Leaf growth rate (irreversible ex
