Figure 1.
Effects of salinity on seed germination of E. agallocha.
Figure 2.
Effects of salinity on growth of young seedlings.
Growth parameters include stem basal diameter, stem height, leaf number and maximum leaf area of young E. agallocha seedlings cultivated with 1.0 strength Hoagland solution. Mean and SD of three replicates are shown, and means at the same salinity with different letters are significantly different at 0.05 according to 1-way ANOVA test.
Figure 3.
Effects of salinity on growth of old seedlings.
Growth parameters include stem basal diameter, stem height, leaf number and maximum leaf area of old E. agallocha seedlings cultivated with 1.0 strength Hoagland solution. Mean and SD of three replicates are shown, and means at the same salinity with different letters are significantly different at 0.05 according to 1-way ANOVA test.
Figure 4.
Effects of salinity and nutrient on growth of old seedlings.
Growth parameters of stem basal diameter, stem height, leaf number and maximum leaf area were measured after 120 days cultivation. Mean and SD of three replicates are shown, and means at the same nutrient level with different letters are significantly different at 0.05 according to 1-way ANOVA test. HN: high nutrient, fertilized with 1.0 strength Hoagland nutrient solution; LN: low nutrient, unfertilized.

Figure 5.
Effects of salinity and nutrient on biomass partition and RGR of old seedlings.
Parameters of total biomass, S/R and RGR were measured after 120 days cultivation. Mean and SD of three replicates are shown, and means at the same nutrient level with different letters are significantly different at 0.05 according to 1-way ANOVA test. HN: high nutrient, fertilized with 1.0 strength Hoagland nutrient solution; LN: low nutrient, unfertilized.
Figure 6.
Effects of salinity and nutrient on leaf gas exchange of old seedlings.
Physiological parameters include Pn, Tr, gs and WUE. Mean and SD of three replicates are shown, and means at the same nutrient level with different letters are significantly different at 0.05 according to 1-way ANOVA test. HN: high nutrient, fertilized with 1.0 strength Hoagland nutrient solution; LN: low nutrient, unfertilized.
Figure 7.
Effects of salinity and nutrient on salt content and proline accumulation of old seedlings.
Mean and SD of three replicates are shown, and means at the same nutrient level with different letters are significantly different at 0.05 according to 1-way ANOVA test. HN: high nutrient, fertilized with 1.0 strength Hoagland nutrient solution; LN: low nutrient, unfertilized.
Figure 8.
Effects of salinity and nutrient on MDA contents, CAT and SOD activities of old seedlings.
Mean and SD of three replicates are shown, and means at the same nutrient level with different letters are significantly different at 0.05 according to 1-way ANOVA test. HN: high nutrient, fertilized with 1.0 strength Hoagland nutrient solution; LN: low nutrient, unfertilized.
