Influência de preparados homeopáticos sulphur e chamomila sobre a germinação e desenvolvimento inicial de cultivares de feijão comum

Abstract

The common bean (Phaseolus vulgaris L.) has considerable nutritional, economic, and social importance, particularly for family farming. This study aimed to evaluate the influence of the homeopathic preparations Sulphur and Chamomila on the germination and initial development of three common bean landraces: Rajado, Preto, and Amarelo. The experiment was conducted using a completely randomized design in a two-factor factorial arrangement, with five treatments: control, Sulphur 18CH, Chamomila 18CH, Sulphur 30CH, and Chamomila 30CH and three cultivars: Rajado, Preto, and Amarelo. Germination percentage, root and shoot length, and seedling fresh and dry mass were evaluated. The data were subjected to analysis of variance and mean comparison tests. The Rajado and Amarelo landraces showed high germination percentages, with no significant differences among treatments. The Preto landrace showed lower germination in all treatments, possibly due to the lower physiological quality of the seeds. For this landrace, Sulphur 30CH and Chamomila 30CH significantly reduced germination compared with the control and the 18CH dynamizations. The results indicate that the response to homeopathic preparations depends on the landrace and the dynamization used.
