ABSTRACT: This research aimed to evaluate the action of potencies of Natrum muriaticum in detoxification of seeds of Solanum lycopersicum after salt stress. The experiment was carried out at the Laboratory of Plant Ecophysiology of UNEMAT / CUAF in a completely randomized design. It was used 800 seeds of cv. Cereja, without defensive treatments, divided into eight treatments with four replications. Five of these treatments have undergone a process of intoxication (-0.8 MPa NaCl salt stress) and detoxification (water or homeopathic solution 5CH, 7CH, 9CH, 12CH), salt stress (only intoxication) a control treatment (water only) and dry treatment (dry seed). Seeds were placed in gerbox (blotter-test), keeping them in a germination chamber at 25 ° C, photoperiod of 12 hours. After 14 days it was evaluated the germination percentage (G%), germination speed index (IVG), average length of root (CR), average length of shoot (CPA) and dry matter (MS). Salt stress interfered in all variables differing from the other treatments, the procedure of detoxification by homeopathic doses proved effective, especially in %G and IVG, and did not differ for MS and CPA, while the average for CR treatments detoxified by N. muriaticum were superior to treatment with water. Treatment of tomato seeds with N. muriaticum after stress is feasible and efficient.
