Background: Aluminum toxicity is the most important factor limiting the growth of plants in acid soils, whereas current treatments are unfeasible. For this reason, alternatives are sought for, among which homoeopathic treatment. Aims: This study aimed at evaluating the influence of homoeopathic preparations Alumina 6cH, Alumina 12cH, Calcarea carbonica 6cH and Calcarea carbonica 12cH on the germination and vigor of lettuce seeds subjected to toxic levels of aluminum in paper-solution. At the same time, it was sought to develop a new procedure to apply homoeopathic preparations in plants (pelleting). Methods: The statistical design was entirely randomized (CRD) with 6 treatments and 4 repetitions. Treatments included: 1) pelleted seeds/talc + Alumina 6 cH; 2) pelleted seeds/talc + Alumina 12cH; 3) pelleted seed/talc + Calcarea carb 6cH; 4) pelleted seeds/talc + Calcarea carb12cH; 5) pelleted seeds/talc + distilled water; 6) non pelleted seeds (control). Variables evaluated were: germination percentage (GP), germination speed index (GSI) and radicle length (RL). Results: There was significant difference in GSI and RL - variables that reflect the vigor of seeds - between the samples treated with homoeopathic preparations and the controls Conclusions: Homoeopathic preparations Alumina 6cH and 12cH and Calcarea carbonica 6cH and 12cH had significant effect on the vigor of lettuce seeds subjected to stress conditions.
