Alelopatia de Piptadenia moniliformis e Capparis hastata sobre o vigor de sementes de Mimosa hostilis

Abstract: O reflorestamento tem sido incentivado em todo mundo por fornecer uma melhoria no ecossistema terrestre, logo para obter sucesso é necessário utilizar espécies vegetais que sejam compatíveis entre si, com ausência de propriedades inibitórias que afetem e prejudiquem o estabelecimento e com isso venha a restringir a eficiência dos reflorestamentos. No presente estudo, objetivou-se verificar possíveis efeitos alelopáticos exercidos por extratos aquosos de folhas frescas de Capparis hastata e Piptadenia monilifor… Show more

“…By submitting A. cearensis seeds to different concentrations of Cynophalla hastata, Silva et al (2021) [19], observed that regardless of the concentration of the aqueous extract there was a significant reduction in the percentage of emergence in relation to the control (concentration 0%), the following allelopathic compounds were found in the aqueous extract of C. hastata leaves: alkaloids, saponins, phenolic compounds and flavonoids. Inhibitory action on germination and initial development of Mimosa hostilis seedlings was verified by Silva et al (2020) [20], when aqueous extracts of fresh leaves of Piptadenia moniliformis and Capparis hastata were used; the authors attributed the results to the presence of chemical substances in the leaves with an allelopathic effect. The concentrations zero, 25 and 50% provided the highest rate of emergence.…”

“…De maneira geral, as substâncias alelopáticas ao interferirem na divisão celular, na permeabilidade de membranas, na ativação de enzimas e na produção de hormônios nas plantas, acabam inibindo ou retardando o processo germinativo das sementes e o desenvolvimento/crescimento das plantas (Rodrigues et al, 1992). Dentro desse contexto, Silva et al (2020) verificaram efeito inibitório de extratos aquosos das folhas de Capparis hastata e Piptadenia moniliformis, sobre o processo de germinação e estabelecimento inicial de M. hostilis. O mesmo foi observado por Torquato et al (2020) por ocasião da submissão de diásporos de alface e C. echinatus L., aos extratos aquosos de S. cearensis.…”
