Abstract:
:Experiments were conducted in growth chambers to examine the effect of a mild water stress (-200 kilopascals polyethylene glycol) on frond elongation and water status of the ostrich fern (Matteuccia struthiopteris [L.] Todaro). Measurements were taken for two days, starting one day after the application of polyethylene glycol. Total water potential in control (well-watered) plants was always significantly higher in immature fronds than in mature fronds. The osmotic potential in mature fronds was always significantly lower (about 800 kilopascals) than in immature fronds in both control and stressed plants. In immature fronds, the stress decreased elongation and total water and pressure potentials, while in mature fronds it increased total water and pressure potentials. The decreases in total and pressure potentials in immature fronds were approximately equal to the increases in mature fronds.
