Potencial alelopático de extratos aquosos de frutos de Solanum americanum Mill. sobre as sementes de rabanete

Abstract: Potencial alelopático de extratos aquosos de frutos de Solanum americanum Mill. sobre as sementes de rabanete RESUMO O objetivo deste trabalho foi investigar o potencial alelopático de extratos aquosos de frutos de erva-moura (Solanum americanum Mill.) sobre a germinação da semente e o crescimento inicial da plântula de rabanete (Raphanus sativus L.). Os extratos foram preparados nas concentrações 2; 4 e 8% e caracterizados quanto ao pH, potencial osmótico e perfil fitoquímico. Os testes foram constituídos de … Show more

“…Similar results were obtained for the germination and early growth inhibition of radish using aqueous leaf extracts of Andira humilis (PERIOTTO et al, 2004), Cyperus rotundus (ANDRADE et al, 2009) and Solanum americanum (BORELLA et al, 2012). Wheat caryopses treated with aqueous leaf extracts of Fumaria indica and Polygonum plebejum also exhibited inhibited germination and seedling growth (ULLAH et al, 2013).…”

“…Com relação ao CPA e ao CPR, os extratos decocto e macerado se diferiram nas concentrações 3, 6, 12, 25 e 50 mg mL -1 ; o primeiro apresentou as menores médias de CPA, enquanto o segundo apresentou as menores médias de CPR (Tabela 3). Borella et al (2011), ao analisarem o efeito alelopático de Solanum americanum Mill. com extratos aquosos obtidos por trituração, verificaram uma redução do CPR de plântulas de rabanete.…”

“…According to Chou (1999), photosynthesis is affected by allelochemicals, since they cause changes in the chlorophyll content of the target plants. The reduction of chlorophyll may be attributed to biosynthesis inhibition by allelopathic compounds (Borella et al, 2012). Besides, Dayan et al (2000) explained that the phenotypic response to a phytotoxin might be the result of secondary effects, rather than the primary mechanism of action of the compound.…”
