“…This is in agreement with earlier studies reported that salt stress induced ion imbalance (Parihar et al, 2015), destruction of membrane permeability (Jabeen et al, 2014;Wang et al, 2016), and oxidative stress (Li et al, 2011), leading to seed germination and plant growth dramatically restricted. If the salt stress exceeded the limits of salttolerant, plants will not germinate, as seen at 200 mM NaCl concentration, in this study, which is in agreement with earlier works (Murkute et al, 2005;Li et al, 2016).…”

“…As a result, enhanced antioxidant responses lead to the breeding programs (Li et al, 2011). Plants show low solute potential in salt stress (Sebei et al, 2007;Wang et al, 2016;Parihar et al, 2015), resulting in physiological disorder or death. Salt stress often leads to the burst of reactive oxygen species (ROS) (Li et al, 2011), such as hydrogen peroxide (Almansa et al, 2002), superoxide radical and hydroxyl radical (Ei-Mashad, 2012) in cell, thereby triggering protein degradation (Wang et al, 2014) and the enzymatic antioxidant defense system abnormal (Li et al, 2011;Ei-Mashad, 2012;Keyster et al, 2013).…”

Article InfoThis experiment was conducted to determine the effect of salt stress (0, 50, 100, 150 and 200 mM NaCl) on plant growth and antioxidative defense of Kumquat (Fortunella margarita) seedlings in vitro. Stem diameter, leaf number, plant height, root morphology, leaf superoxide dismutase (SOD) and catalase (CAT) activities, and leaf soluble protein content were determined. The Kumquat germination percentage and plant growth significantly reduced with the increasing of NaCl concentrations, and only keeping vitality and no germination in seeds were at 200 mM NaCl concentration. Root biomass and morphological traits (length, projected area, surface area, average diameter, volume, and tips) gradually decreased with the increasing of NaCl concentrations. The leaf soluble protein content and CAT activities of Fortunella margarita significantly decreased with the increasing of NaCl concentrations in vitro, but leaf SOD activities had the highest activity at 50 mM NaCl. It may be suggest that NaCl stress heavily inhibited seed germination at 200 mM level and plant growth and root morphology, and only the kumquat plants possessed an antioxidant enhancement in 50 mM NaCl.

“…Stomatal conductance is an important indicator of stomatal control of water loss and CO 2 assimilation. Lowered stomatal conductance in plants exposed to salt stress may be due to a reduction in water potential or disturbances in photosynthesis and respiration [Parihar et al, 2015].…”

“…Soil salinity along city transportation routes is due to human activity, such as using sodium chloride to remove snow from roads, streets, and pavements [Bach et al, 2009]. Salt concentrations that exceed plant tolerance level cause growth inhibition [Villarino and Matsson, 2011], reduce flower quality [Sonneveld et al, 1999], trigger leaf browning and drying [Cassaniti et al, 2012], and finally result in plant organ death [Niu and Cabrera, 2010;Parihar et al, 2015]. Salinity has a negative impact on photosynthesis [Vetach-Blohm et al, 2013], water management [Ma et al, 2012] and enzymatic activity [Zhang et al, 2014].…”

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.

“…Osmotic stress is a phenomenon also observed in plants under high salinity (Parihar et al 2015). Soybean plants incubated with SNP prior to salt stress exhibited higher relative water content (RWC) than salt-stressed plants devoid of NO treatment (Dinler et al 2014).…”

High salinity aff ects plants due to stimulation of osmotic stress. Cell signaling triggered by nitric oxide (NO) and hydrogen sulfi de (H 2 S) activates a cascade of biochemical events that culminate in plant tolerance to abiotic and biotic stresses. For instance, the NO/H 2 S-stimulated biochemical events that occur in plants during response to high salinity include the control of reactive oxygen species, activation of antioxidant system, accumulation of osmoprotectants in cytosol, induction of K + uptake and Na + cell extrusion or its vacuolar compartmentation among others. Th is review is a compilation of what we have learned in the last 10 years about NO participation during cell signaling in response to high salinity as well as the role of H 2 S, a new player in the mechanism of plant tolerance to salt stress. Th e main sources of NO and H 2 S in plant cells is also discussed together with the evidence of interplay between both signaling molecules during response to stress.
