  • 摘要:This paper deals with an experiment in which wheat seeds were stressed with a material dose of As2 O3, and then treated with ultra-molecolar dilutions of the same substance, with and without potentization. We focused our analysis on seedling stem length during 7 days of treatment, and tried to give a thorough statistical description of the data. We applied simple nonparametric tests for comparing treated and control groups: it seems to be a significant stimulating effect when seeds are treated with the 45th decimal potency of As2 O3 . A similar effect was obtained in a previous experiment (Betti et al., 1997), and shows that our model allows a proper reproducibility of results.
