“…Results showed that, plant height was decreased under saline condition which was also found in tomato with increased levels of salinity mostly at 6 and 8 dS m -1 [17]. Similar results were also recorded in tomato [18], lettuce [19] and coriander [20].…”

“…Saberi et al [26] also obtained reduced number of leaves plant -1 under salt stress. Leaf number was decreased under saline condition mostly at 6 and 8 dS m -1 in tomato [17]. So it is suggested that the SA application improved leaves production by reducing the effect of salt.…”

“…According to Hernandez et al [21] salt stress deprived the normal cell behavior and reducing leaf expansion as well as reduced leaf area. Salinity also adversely affected leaf area mostly at 8 dS m -1 in tomato [17]. Salinity reduces the plant growth resulting foliage coverage was decreased.…”

Introduction: This experiment was set up to investigate the beneficial effect of salicylic acid to reduce the harmful consequence of salinity on cabbage productivity where Salt stress severely limits plant growth, development and yield. Methods: We had grown cabbage plants under different levels of NaCl salinity (0, 4, 8 dS m -1 ) alone or supplemented with foliar spray of different concentrations of salicylic acid (SA, 0, 0.25 and 0.5 mM). This experiment was laid out in a randomized complete block design with three replications. Collected all data were statistically analyzed following the analysis of variance (ANOVA) technique using MSTAT-C program and the mean differences were adjudged by least significant difference (LSD) test at 5% level of significance. Results: Results showed that, higher concentrated salt treated plants give the significant lower growth and head yield. Plant growth as well as yield of cabbage such as heads thickness, diameter and weight were decreased with increased level of salinity such as 8 dS m -1 compared with other treatment. While, foliar application of SA increased growth and yield also hindered stress induced growth and production inhibition. The improvement in plant height, leaf number, leaf length and breadth, foliage coverage, number of root and weight, head thickness, diameter and weight were increased with increased concentration of SA and higher value were recorded from 0.50 mM SA. Conclusions: It can be concluded that SA improve the plant defense system to resist the toxic effect of salinity.

“…These opposite results can be explained by a genotype dependent response. In tomato, Parvin et al (2015) reported similar tendency indicating that the fruit weight is gradually decreased with the increased levels of salinity. In vegetable crops, it is well known that salt stress decreases marketable yield due to decreased productivity and an increased unmarketable yield of fruits, roots, tubers and leaves without commercial value (Machado and Serralheiro, 2017).…”

Salt stress is one of the major environmental constraints limiting agricultural productivity and influencing the concentration of bioactive compounds of vegetables. In this study, we assessed the effect of NaCl salt stress on flowering, fructification and fruit nutritional quality of a local cultivar of chili pepper. The experiment was carried out in a screen house as a completely randomized design (CRD) with three replications. Three weeks old plants were submitted in pots containing a mixture of potting soil and sand, to five NaCl concentrations; 0, 30, 60, 90 and 120 mM NaCl by irrigation every two days for 94 days. Salinity retarded significantly flowering and fruit ripening, and reduced significantly the fruit number, as the NaCl concentration increased with no fruit obtained at 90 and 120 mM NaCl. Fruit size and fresh mass were also significantly reduced by salt stress. Capsaicinoids contents increased significantly for about 389% in comparison to the control at 60 mM NaCl, whereas vitamins B6, B12 and C contents decreased significantly with increasing NaCl concentration. Thus, salt stress retarded flowering and fruit ripening; reduced fruit number, size and mass; enhanced fruit tangy appearance and deteriorated fruit nutritional values in chili pepper.

Tomato (Lycopersiconesculentum L.) is a long duration crop belongs to a family Solanaceae. In case of vegetables, tomato is a second major crop, cultivated wide range throughout the world. Although, tomato is moderate sensitive to salinity yet for salinity tolerance more attention is required. More than 30% cultivated land all over the world severely affected by the salinity. In this scenario, experiment was designed to investigate various morphological and physiological aspects of tomato under various salinity levels; different levels of exogenous glycine betaine applications. Study was conducted to reveal the salt tolerance in tomato genotypes. Experiment was performed under controlled condition in the growth chamber of the IHS, UAF. Different concentrations of sodium chloride salt (0, 1.5 and 3 dS m-1) was used for salinity levels. Medium size plastic pots were used for sowing of tomato and sand was used as growing medium. Hoagland solution was applied for nourishment of tomato seedlings. Salinity was applied on 3-4 leaf stage. Then examined the effect of glycine betaine (0, 5, 10 and 15mM) for salt tolerance on tomato cultivars. Data of various attributes was collected and analyzed statistically by appropriate statistical package. Results revealed that tomato growth was negatively affected by the salinity. Morphological attributes and physiological attributes reduced in response to salinity except electrolyte leakage which amplified in salt stress. Exogenous application of glycine betaine promotes the tolerance against the salinity in the tomato genotypes and enhance growth.
