“…However, at concentrations at or below 75 mM NaCl, leaves of S. splendens were thickened, rubberized, and very hard to tear off. As previously reported, in two ornamental plants, Coleus blumei and S. splendens , leaf thickening is a common response to high salt level .…”

A greenhouse study at increasing salt concentrations (0, 25, 50, 75 and 100 mM NaCl) with or without hydrogel amendment was conducted during a 10‐week period in order to examine growth and aesthetic responses of three Salvia species. Subsequent analyses revealed that 25, 50 and 75 mM NaCl concentrations had a positive impact on the plant growth (plant height, plant width, fresh weight, and root system volume), while 100 mM NaCl implied a negative response. The positive effect of the hydrogel was most notable in the plant fresh and dry weight, K+ and Ca2+ content, and root system volume. The results further indicate that the amended hydrogel provided sufficient amount of available water and ions that are usually in competition and are limited by excessive Na+ ion amounts. The hydrogel also mitigated the negative influence of higher salt concentrations (75 and 100 mM NaCl), thereby decreasing leaf damage, defoliation, and petal loss, while also improving vitality and aesthetic value of S. farinacea and S. coccinea. In S. splendens, the hydrogel contributed to better vitality but slightly decreased decorativeness. Both qualitative (visual salt damage) and quantitative (growth) parameters proved to be reliable criteria for assessing salt tolerance of the studied Salvia species, while ion removal contributes to the understanding of salt tolerance mechanisms and possible usages.

“…This increase was proportional to the increase in irrigation water salinity. Similar trends in Na accumulation in shoots of Coleus were reported by Ibrahim et al, (1991). Sodium content per unit dry weight was comparable for all three plant species, and the degree of salt injury increased with increasing salinity.…”

The salinity tolerance of local varieties of five ornamental species Begonia, Chlorophytum, Coleus, Geranium, and Mesembryanthemum was assessed in a medium term pot experiment. The pot grown plants were watered for 50 days with water salinised at 5 dS/m and 15 dS/m and a tap water control.Based on growth parameters and on survival, Begonia was classified as salt sensitive, Coleus, Geranium, and Chlorophtytum as moderately tolerant, andMesembry-anthemum as salt tolerant. Shoot sodium (Na) content was measured at the end of the experiment. It appears that the restriction of Na entry to the shoot is linked to salinity tolerance. Mesembryanthemum seems to be able to control Na entry to the shoot at water salinities above 5 ds/m.

“…800 mmol NaCl·dm -3 produced the lowest number of leaves. Reduced number of leaves in plants exposed to excessive salinity was also observed in such bedding plants as Coleus blumei 'Xenia Field' and Salvia splendens 'Flare Path' [Ibrahim et al 1991]. The plants treated with 800 mmol NaCl·dm -3 produced the shortest leaves with the narrowest blades, as compared with other and non-treated control plants (Table 4).…”

Ornamental plants growing in urban areas are exposed to soil salinity that negatively affects their quality. Identifying species that retain high ornamental value despite salt stress is therefore of high practical importance. Curly kale (Brassica oleracea L. var. sabellica L.) is an attractive plant with leaves of both edible and ornamental character. The aim of the study was to evaluate a response of ornamental curly kale to different concentrations of NaCl. The study material was 'Scarlet' cultivar. The plants were grown in pots in a plastic tunnel. They were irrigated with NaCl solution at the following concentrations: 50, 100, 200, 400, and 800 mM mmol ·dm -3 . NaCl treatment resulted in a significant increase in pH and electrical conductivity (EC) of the substrate. Salt stress significantly affected plant growth and number, width and length of leaves, and the effects depended on NaCl concentration. Fifteen days after the salt supply ceased, relative chlorophyll content in leaves (SPAD) decreased due to NaCl treatment in a concentration-dependent manner. Treatments with 200, 400, and 800 mmol·dm -3 NaCl reduced stomatal conductance, and the changes were greater on the 5th day following the stress cessation than on the 15th day. Irrigation with a 200, 400, and 800 mmol·dm -3 NaCl solution negatively affected plant bonitation score. The plants treated with 50 i 100 mmol·dm -3 NaCl were not significantly different visual score from the control plants.
