The aim of this study was to investigate the response of Gladiolus grandiflorus to zinc (2, 4 and
6 mg kg-1) application and various salinity levels (2, 4 and 4 dS m-1) of irrigation water. The analysis results of morphological and growth attributes of Gladiolus indicated significant reduction in the investigated attributes with increased in salinity, while zinc application
alleviated the stress by increasing morphological and growth parameters. Furthermore, the study
demonstrated that the continuous irrigation of saline water lead to a decrease in membrane
stability index and relative water content, these were well-linked with reduction in the enzyme
activity. Although soil application of zinc levels decreased the salinity stress, but the most
pronounced results were obtained at low level of salinity (2 dS m-1) provided with different zinc doses (2-6 mg kg-1). It is concluded that soil application with zinc may have a potential role for increasing Gladiolus tolerance to salinity stress.
