Physiologically, high concentrations of soluble salts in the soil disturb nutrient uptake, cause protein denaturation, and inhibit plant photosynthesis, stomatal conductance, and biosynthetic processes ( Munns and Tester, 2008 Taiz et al., 2015). More resource inputs such as seeds, water, and fertilizers are needed to make up for the loss of plant quality under salinity stress. Stunted growth, biomass reduction, and inhibited bud formation also happen when plants are grown under salinity stress ( Taiz et al., 2015). Salinity can cause foliar damage including necrosis, burn, scorch, and premature defoliation ( Munns, 2002). Salinity negatively affects plants’ morphological development and physiological processes.

However, rose of sharon was the most salinity-tolerant species among the three landscape plants. We were not able to define the salinity threshold for rose of sharon in this study.
Rose of sharon ( Hibiscus syriacus), ninebark ( Physocarpus opulifolius), and japanese spirea ( Spiraea japonica) were irrigated using an NCGD system with eight electrical conductivity (EC) levels ranging from 0.9 to 6.5 dS A near-continuous gradient dosing (NCGD) system allows researchers to evaluate a large number of plants for salinity tolerance with multiple treatments, more flexibility, and reduced efforts of irrigation.
