Grafting on a moderate salt-tolerant rootstock (Vista-306) and bacteria (Serratia marcescens) inoculation were tested whether grafting and bacteria can alleviate salinity stress in eggplant. Two salt-tolerant eggplant genotypes ('Mardin Kızıltepe', 'Burdur Merkez') and two salt-sensitive eggplant genotypes ('Artvin Hopa', 'Kemer') were used as scions. Grafted and non-grafted seedlings with 4–5 true leaves were transferred to pots filled with a mixture of peat: perlite (2:1) in a controlled greenhouse and were cultivated under temperatures of 23–25 °C with approximately 50–55% relative humidity. After 10 days from planting, 20 mL bacteria solution (cell density of 3 × 108 cells mL−1) per plant was applied to the root region of the seedlings as inoculum. 200 mM NaCl solution was applied to plants for 20 days after 5 days from inoculation of the bacteria. The study was arranged in a randomized block factorial design with three replicates. The grafted seedlings induced salt tolerance registering lower foliar concentrations of Na+ and Cl–, the lower lipid peroxidation and higher antioxidative enzyme activities. Inoculation of the bacteria significantly counteracted the salt-induced adverse effects on growth characteristics, leaf Cl−, Na+ contents, and antioxidative enzyme activities. In conclusion, grafting and inoculation with Serratia marcescens are effective in improving growth and some key physiological processes in eggplant under salt stress. [ABSTRACT FROM AUTHOR]

The effects of salt (NaCl) applications of various concentrations (0, 500, 1000, and 2000 mg/L) for 10 weeks (69 days) on the morphologic properties and ionic composition of the "Camarosa" straw- berry variety grown in perlite and perlite : zeolite (1:1) media were investigated. Injuries of varying severity appeared in the plants depending on the increase of NaCI concentration. At the end of the salt applications, in the aerial part of the plants, the amounts of sodium (Na), chlorine (Cl), calcium (Ca), and magnesium (Mg) had generally increased, while the amount of potassium (K) and phosphorus (P) had decreased. in the roots of the plants, salt applications increased the amount of Na and Cl and decreased the amount of K and Mg; however, they did not change the amount of Ca and P. In addition, in the aerial parts of the plant, the amounts of Ca and Mg were higher in the perlite : zeolite (1:1) medium than in the perlite medium generally. It was observed that in the roots, the amount of K was higher in the perlite medium, whereas the amount of Mg was higher in the perlite: zeolite (1:1) medium. It was determined that 500, 1000, and 2000 mg/L NaCI levels caused osmotic effects in the "Camarosa" strawberry variety. Moreover, they possess the ability to bring about osmotic regulation.
