In this study, it is aimed to clarify how the metabolic events in the plant and pepper plant are affected under salt stress and recovery process, and which adaptation mechanisms are developed. Seedlings germinated in pumice environment and 2 true leaf seedlings were taken into water culture, and salt applications were started to be applied to seedlings in the period of 4-5 leaves. Before salt application (0. day) plant samples were taken, 50 mM NaCl was added to nutrient solution for seedlings to be applied salt. Sampling was performed on the 10th and 20th days of the salt application period and recovery period. Some basic growth parameters of plants are number of leaves, leaf weight, root weight, root length, stem weight, plant height, first flowering, in leaf Na, K, Ca, Cl contents were performed. As a result of the measurements and analyzes, it was observed that salt stress had a negative effect on plant growth parameters in both pepper cultivars. Carliston pepper cultivar was able to recover the plant growth on the 20th day of the recovery process (post-stress process), while the hot pepper cultivar was able to control the plant growth by limiting the plant growth in order to control the metabolic activity. When the effect of salinity on the early flowering of plants was observed, it was observed that the first flowering of the charliston pepper cultivar was on the 23rd day of salt application. As a result of the biochemical analysis, it was determined that the negative effect of salt stress on the plants decreased on the 20th day of the recovery process.
