“…Miceli et al (2003) reported that lettuce plants under salt stress conditions may decrease their water uptake and change the absorption ratio of nutrients. Additionally, Turhan et al (2013) indicated that NO3-N concentration significantly decreased in salt-stressed spinach (Spinacia oleracea L.) plants.…”

This study was carried out to investigate the effects of irrigating lettuce (Lactuca sativa L. cv. Funly) with different concentrations of diluted seawater (0%, 2.5%, 5%, 10%, 15%, 20%) on the fresh yield, marketable yield and quality (DM, total soluble solids, titratable acidity, total sugar, vitamin C, NO3-N, protein, and total oxalate content). The experiments were conducted in a greenhouse in the autumn of 2012. The fresh yield, marketable yield, and DM of lettuce irrigated with 2.5% and 5% seawater were similar to those of control, but these parameters decreased in response to 10% seawater, and the lowest values were obtained in response to 20% seawater. The 2.5% seawater treatment had no effect on the vitamin C and NO3-N content, but both significantly decreased when lettuce was irrigated with seawater concentrations higher than 2.5%. Total soluble solids, total sugar, and protein content significantly increased in response to low salinity (2.5% and 5%) but decreased in response to increasing seawater stress. The titratable acidity values remained unchanged under the various saline conditions. Irrigation with diluted seawater did not affect the total oxalate content up to a concentration of 5%, but increasing the concentration of seawater above 5% increased oxalate content. The results of this study demonstrated that low concentrations of seawater are suitable for lettuce production and lettuce can be grown successfully using diluted seawater at concentrations of 2.5% and 5%.

“…When salt-sensitive plants are grown in the presence of salt, addition of potassium and calcium has been shown to restore plant growth (Amtmann et al, 2001;Benlloch et al, 1994;Caines and Shennan, 1999;Cramer et al, 1985;Lahaye and Epstein, 1969;Morgan et al, 2014;Rubio et al, 2009;Shabala et al, 2005;Turhan et al, 2013;Zhong and Lauchli, 1994). To determine if addition of potassium and calcium can ameliorate the cbl10 sterile phenotype, KCl and CaCl 2 were added with the NaCl treatments.…”

“…S3). While little is known about the mechanism underlying flower opening and closing, the importance of potassium and calcium has been shown in other reversible movements, including opening and closing of stomata (Kim et al, 2010) and of leaves from Mimosa pudica (Moran, 2007 Turhan et al, 2013) are among the plants with improved growth with addition of calcium or potassium during salt treatments. In these studies, the addition of supplemental calcium reduced sodium levels and increased potassium and calcium levels.…”

Arabidopsis CALCINEURIN B-LIKE10 Functions Independently of the SOS Pathway during Reproductive Development in Saline Conditions

et al. 2016

The accumulation of sodium in soil (saline conditions) negatively affects plant growth and development. The Salt Overly Sensitive (SOS) pathway in Arabidopsis (Arabidopsis thaliana) functions to remove sodium from the cytosol during vegetative development preventing its accumulation to toxic levels. In this pathway, the SOS3 and CALCINEURIN B-LIKE10 (CBL10) calcium sensors interact with the SOS2 protein kinase to activate sodium/proton exchange at the plasma membrane (SOS1) or vacuolar membrane. To determine if the same pathway functions during reproductive development in response to salt, fertility was analyzed in wild type and the SOS pathway mutants grown in saline conditions. In response to salt, CBL10 functions early in reproductive development before fertilization, while SOS1 functions mostly after fertilization when seed development begins. Neither SOS2 nor SOS3 function in reproductive development in response to salt. Loss of CBL10 function resulted in reduced anther dehiscence, shortened stamen filaments, and aborted pollen development. In addition, cbl10 mutant pistils could not sustain the growth of wild-type pollen tubes. These results suggest that CBL10 is critical for reproductive development in the presence of salt and that it functions in different pathways during vegetative and reproductive development.

“…But, germination percentage and germination rate of spinach seed was decreased while mean germination time was increased up to 100 mM NaCl concentration (Keshavarzi et al, 2011). Salinity decreased uptake and endogenous level of K + , Ca 2+ and NO 3- (Turhan et al, 2013), and oxygen uptake (75% reduction) thereby inhibiting the synthesis of enzymes like alkaline phosphatase in spinach plant (Ahmad and Huq, 1974) and thus affected various growth stages. Mwazi (2012) reported that saline irrigation water reduced germination, vegetative growth and yield of Spinach but increased leaf sugar contents.…”

Spinach seeds show low germination percentage and speed due to pericarp imposed physical and chemical hindrance; the problem is further aggravated under saline conditions. To assess seed vigor and repress salinity induced lipid peroxidation, seeds of spinach cultivar 'Desi Palak' were subjected to various treatments viz., soaking in distilled water (for 4 h), washing of seeds with bleach i.e. sodium hypochlorite (for 10 min, 50% of commercial grade), seed priming (30 h) using distilled water i.e. hydropriming (with or without soaking), kinetin (25 ppm, after bleach and soaking; hereafter mentioned as kinetin only for simplicity) or Indole-3-Acetic Acid (IAA 100 ppm, after bleach and soaking; hereafter mentioned as IAA only for simplicity). The effect of seed treatments on seed vigor and salinity tolerance was evaluated through germination test (at 0, 50, 100, 150, and 200 mM NaCl induced salinity) and emergence test (at 0 and 200 mM NaCl induced salinity). Seed priming using IAA showed better final germination and emergence percentage, germination index, germination and emergence energy, seedling biomass, chlorophyll contents and vigor index than control and other seed treatments. All parameters were negatively affected by salinity but were altered to significantly lesser extent in seeds primed with distilled water or IAA, especially IAA at higher (200 mM) salinity levels. Bleach and soaking treatments seemed to soften the pericarp as evident by enhanced germination/emergence, germination energy and index, while reducing mean germination/emergence time. Further seed enhancement and increased biomass production in IAA or hydro-primed seeds (after bleach and soaking) can be attributed to reduced lipid peroxidation as evidenced by low MDA contents in seeds primed with IAA and distilled water, particularly under saline conditions.
