The effects of high dilutions of Cymbopogon winterianus (citronella) on the growth and germination of Sida rhombifolia are analyzed; 5 homeopathic dilutions (3cH, 6cH, 12cH, 24cH, 30cH) and a control (water) were used, with 5 repetitions. Variables analyzed were the primary growth of the root system, length of the shoot, fresh mass total, germination percentage and germination speed index. All dilutions stimulated the primary growth of the root. Dilutions 3cH, 6cH, 12cH and 30 cH stimulated the growth of the aerial parts and 24cH inhibited it. Dilutions 6cH, 12cH, 24cH and 30cH stimulated a larger production of fresh mass than 3cH. Dilution 12cH resulted in the largest germination percentage while 24cH in the lowest. Dilution 12cH resulted in the highest score in the germination speed index, while 3cH and 24cH in the lowest.

Efeitos de altas dilui § μes de Cymbopogon winterianus Jowitt (citronella) na germina § ￡o e crescimento de sementes de Sida rhombifolia Resumo Os efeitos de altas dilui § μes de Cymbopogon winterianus (citronella) no crescimento e germina § ￡o de Sida rhombifolia s ￡o analisados; 5 dilui § μes ho ′meop ticas (3cH, 6cH, 12cH, 24cH, 30cH) e um controle ( gua) foram utilizados, com 5 repeti § μes. As vari veis analisadas foram: crescimento prim rio do sistema da raiz, longitude do broto, massa fresca total, porcentagem de germina § ￡o e -ndice de velocidade de germina § ￡o. As dilui § μes 3cH, 6cH, 12cH e 30cH estimularam o crescimento das partes a reas, que foi inibido pela dilui § ￡o 24cH. As dilui § μes 6cH, 12cH e 30cH estimularam uma maior produ § ￡o de massa fresca que a dilui § ￡o 3cH. A dilui § ￡o 12cH mostrou a porcentagem m xima de germina § ￡o, enquanto 24cH mostrou a m -nima. Igualmente, a dilui § ￡o 12cH resultou no m ximo -ndice de velocidade de germina § ￡o, enquanto as dilui § μes 3cH e 24cH, os m -nimos.
