Preparados homeopáticos na germinação de sementes de alface lactuca sativa l.

Abstract

Homeopathy is a form of alternative therapy that is based on the balance of the living being, acting by energetic stimuli through homeopathic medicines, rebalancing the vital energy of living beings. Its application in agriculture is directly linked to agricultural production free of pesticides and polluting residues. The objective of the present work was to evaluate the effect of homeopathy on seed germination and initial development of Lactuca sativa L. lettuce seedlings in americana and lisa cultivars. The homeopathic preparations used were Arnica montana, Arsenicum album and Sulfur, all in 12 CH and 18 CH dynamizations. The experimental design adopted was a completely randomized design (DIC), with seven treatments and four replications. Germination percentage, germination speed index (IVG), root and shoot length and root and shoot mass were evaluated. Data were submitted to analysis of variance and means compared by Tukey's test at 5% probability. It was observed that with the use of Arsenicum album 18 CH there was a greater increase in shoot mass. However, for the dynamization 12 CH had an inhibitory effect for most variables. It was noted that the Arnica 18 CH treatment had a considerable improvement in germination speed.
