“…As a physiologically compatible solute, proline increased as needed to maintain a favorable osmotic potential between the cell and its surroundings (Demiral and Türkan 2005;Gautam and Singh 2009). Recent studies had some debate on whether proline accumulation enhanced the salt tolerance of plants or proline accumulation was the result of osmotic stress (Wang and Han 2009).…”

“…(Guo et al 2011;He and Zhu 2008;Tang et al 2007). Additionally, salt stress produced plenty of reactive oxygen species (ROS) which stimulated the oxidative damage of lipids, proteins, and nucleic acids, even caused the degradation of membrane system (Demiral and Türkan 2005). For mitigating salt stress damage, salicylic acid (SA) was used in many plants (Ananieva et al 2004;ElTayeb 2005;Guo et al 2011).…”

Salinity has a great influence on plant growth and distribution. A few existing reports on Artemisia annua L. response to salinity are concentrated on plant growth and artemisinin content; the physiological response and salt damage mitigation are yet to be understood. In this study, the physiological response of varying salt stresses (50, 100, 200, 300, or 400 mM NaCl) on A. annua L. and the effect of exogenous salicylic acid (0.05 or 0.1 mM) at 300-mM salt stress were investigated. Plant growth, antioxidant enzyme activity, proline, and mineral element level were determined. In general, increasing salt concentration significantly reduced plant growth. Superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) were stimulated by salt treatment to a higher enzyme activity in treated plants than those in untreated plants. Content of proline had a visible range of increment in the salt-treated plants. Distribution of mineral elements was in inconformity: Na + and Ca 2+ were mainly accumulated in the roots; K + and Mg 2+ were concentrated in leaves and stems, respectively. Alleviation of growth arrest was observed with exogenous applications of salicylic acid (SA) under salt stress conditions. The activity of SOD and POD was notably enhanced by SA, but the CAT action was suppressed. While exogenous SA had no discernible effect on proline content, it effectively inhibited excessive Na + absorption and promoted Mg 2+ absorption. Ca 2+ and K + contents showed a slight reduction when supplemented with SA. Overall, the positive effect of SA towards resistance to the salinity of A. annua will provide some practical basis for A. annua cultivation.

“…In present study, the higher proline accumulation is found at 100 mM of NaCl treatment for 15 days in genotype KM-13 and 30 days in genotype ES2138-2. Proline has been shown to accumulate in response to salinity in a number of plant species [8,23,33]. Since proline accumulation in the Sesame genotypes was well-correlated to their growth attributes and production of this free amino acid in the salt-tolerant genotypes was more notable, it seems that it plays some protective roles against salt stress in sesame, at least in the genotypes used in this experiment.…”

Sesamum indicum L. (family-Pedaliaceae) is an economically important oil seed crop grown in tropical and subtropical countries. It is widely used in food, nutraceutical, pharmaceutical industries. Salinity is considered as the most important abiotic stress limiting to crop production. In this context, the present study was to evaluate the Sesamum genotypes for salinity tolerance. Germinated seedlings (15-d-old) were used to screen the germplsm at different concentrations (0, 25mM, 50mM, 75mM, 100mM) of NaCl and observation was taken after 15 th , 30 th and 45 th days of treatment. Ion content (Na + , Cl -, Ca ++ , Mg ++ and K ++ ) were measured after 15 days of treatment. Fresh and dry weight was less in salt sensitive genotypes than tolerant genotypes. During increase of salinity concentration, all the genotypes had a negative impact on roots. The seedlings showed reduced growth and displayed variation in ion uptake thus accumulating Na + and Cl -in the roots. At higher concentration of salt treatment showed the more dry weight and displayed more effective ion regulation by manipulating low Na + /K + and Na + /Ca ++ ratio. The tolerant genotypes exhibited the lowest shoot Na + content under salinity conditions. Higher proline accumulation was observed at 100 mM after 15 days of NaCl treatments in 'KM-13' genotype. After 15 days of treatment, the genotype 'ES 2138-2' showed maximum proline accumulation. The total carbohydrates contents increased in all the ten genotypes in presence of NaCl. Highest carbohydrate content was found in genotype 'SI-1926' grown in 100 mM NaCl. Enzyme activities are variable in different genotypes with different concentration of NaCl. This study will help in Sesamum improvement programme.
