Background and Objective: Banana plants are agricultural crops, particularly horticulture, mostly consumed by many people. Banana plants are considerably influenced by biotic and abiotic environmental factors. Stresses caused by abiotic factors, is one of which caused by salinity, will result in decreased production of bananas, because these plants are very sensitive to salinity. This study aimed to investigate the response of banana plants to salinity stresses in vitro culture. Materials and Methods: Explants of banana Musa acuminate L. var. Barangan and basic medium murashige and skoog, benzyl amino purine, sugar, jelly, NaOH, HCl were used. Statistic analyzed with analysis of variance and Duncan test. The experimental design used was randomize complete design with two factors, factor I: Sodium chloride (NaCl) treatments of various concentrations, i.e., 0, 50, 100, 150 and 200 mM and factor II: Time after culture, in 1, 2, 3 and 4 weeks after culture. Observations over growth parameters were performed on height, wet weight and dry weight of banana plantlets at 1, 2, 3 and 4 weeks after cultures. Statistical analysis was done by one way analysis of variance. Results: The statistical analysis showed no significant differences in the plant height, salinity inhibits the growth of banana plantlets in term of the parameters of height, wet weight of shoots and roots, dry weight of shoots and roots of the banana plantlets. A treatment of 200 mM NaCl indicated that plantlet growth is inhibited in term of height (2.6500 cm), wet weight of shoots (0.0917 g) and roots (0.1957 g) and dry weight of shoots (0.0096 g) and roots of banana plantlets (0.02009 g). Conclusion: Plant growth in saline stressed concentration of NaCl 50, 100 and 150 mM.
