      abstract     = {Plant growth response to salinity on a scale of years has
                      not been studied in terms of growth analysis. To gain
                      insights into this topic, 2-year-old Mediterranean Fan Palm
                      (Chamaerops humilis L.) and Mexican Fan Palm (Washingtonia
                      robusta H. Wendl) seedlings, each with its own distinct
                      plant morphology, were grown for 2 years in a peat soil and
                      irrigated with water of 2 dS m(-1) (control) or 8 dS m(-1)
                      (saline). Plants were harvested on seven occasions and the
                      time trends in relative growth rate (RGR, the rate of
                      increase of biomass per unit of biomass already existing)
                      and its components were analysed. In the long term, salinity
                      produced a slight reduction in the mean RGR, values in both
                      species. In the short term, salinity caused a reduction in
                      RGR. However, during the second year, plants irrigated with
                      8 dS m(-1) grew somewhat more quickly than the control
                      plants, probably as a result of delay in the growth kinetics
                      due to salinity. Regarding RGR components, leaf nitrogen
                      productivity (the rate of biomass gain per unit leaf N and
                      time) was the major factor causing the differences in RGR
                      resulting from salinity. Washingtonia robusta showed a
                      relatively high plasticity in plant morphology by increasing
                      root and decreasing stem biomass allocation in the presence
                      of salinity. However, the long-term response of W. robusta
                      to salinity, based to a great extent, on this morphological
                      plasticity, was less effective than that of C. humilis,
                      which is based mainly on the contribution of leaf N to RGR
                      values.},
