Salt Tolerance of Some Tomato (Solanum lycoversicum L.) Cultivars for Salinity under Controlled Conditions
Mohammad Ibrahim Al-Daej

Background and Objectives: Salinity stress is one of the main factors affecting the optimal yield of many vegetable crops considered as salt sensitive at early growth stages. The objective of this study was to study the salt tolerance of some tomato (Solanum lycoversicum L.) cultivars under laboratory conditions using different levels of NaCl. Materials and Methods: The experiment was carried out in vitro under laboratory conditions. Out of 10 varieties, only two cultivars namely “Rams” and “C10” were selected for investigation based on their physical characteristics. Both cultivars were subjected to 0, 20, 40, 60, 80 and 100 mM NaCl concentrations. The physiological characters such as seed germination, plant length, fresh weight, dry weight and number of leaves were studied against the salt stress. Also, the concentration of K, N, Na and Ca was determined in plant leaves. Results: The results showed that the cultivar Rams performed better than C10 for all the physical properties i.e., germination (%), fresh and dry matter yield etc. Also, the cultivar Rams accumulated less Na and K ions compared to cultivar C10. The cultivar Rams proved more salt tolerant even at high levels of salinity. Conclusion: Based on the studying findings, cultivar Rams proved more tolerant to salinity compared to other cultivars. Therefore, it can successfully be used in future breeding programs for its better salt tolerance capabilities to achieve optimal crop yield.
