Salinity is an ancient environmental phenomenon and reflected as the most important process of land degradation. It is widespread at variable degrees across the world. A sand culture study was conducted in order to investigate the performance of exogenously applied triacontanol on two tolerant (Green long and Marketmore) and two sensitive (Summer green and 20252) genotypes of cucumber (Cucumis sativus L.) under salinity stress (NaCl 50 mM). The foliar application of triacontanol was carried out @ 0.20, 0.40, 0.60, 0.80, 1.00 and 1.20 mg L-1. Salinity caused significant reduction in growth rate, gas exchange and other physiological attributes. Results revealed that triacontanol seemed to relieve the harmful impact of salt stress by improving morpho-physiological attributes and decreasing membrane leakage. Genotypes Green long and Marketmore performed better under salt stress regarding all studied parameters than Summer green and 20252. However, foliar feeding of triacontanol significantly enriched the efficiency of sensitive genotypes under saline conditions. The highest values of different attributes of cucumber plants were observed with foliar application of 0.80 mg L-1 triacontanol. Hence, triacontanol can be effectively used as a mitigating agent to alleviate phytotoxic effects in plants under saline stress.

Salt stress, among other abiotic stresses, has a high impact on crop yield. Salt tolerance is a multifactorial trait that involves the ability of cells to retain K ions, regulate reactive O species (ROS) production, and synthesise new molecules to cope with osmotic stress. In the present work, two different cultivars of Cucumis sativus L. (cv. Parys, sensitive; cv. Polan, tolerant) were selected based on their germination capabilities under 100 mM NaCl. The capacity of these two cultivars to tolerate salt stress was analysed using several different physiological and genetic approaches. K+ fluxes from roots, as an immediate response to salinity, showed the higher ability of cv. Polan to maintain K+ compared with cv. Parys, according to the expression level of inward rectifying potassium channel 1 (AKT1). ROS production was also investigated in both cultivars and a higher basal ROS level was observed in cv. Polan than in cv. Parys. Concurrently, an increased basal level of respiratory burst oxidase homologue F (RBOHF) gene was also found, as well as a strong induction of the ethylene responsive factor 109 (ERF109) transcription factor after salt treatment in cv. Polan. Our data suggest that roots’ ability to retain K+, a higher level of RBOHF and a strong induction of ERF109 should all be considered important components for salt tolerance in C. sativus.
