“…In the evaluation of coffee fruit extracts (Coffea arabica) , the concentration required for the growth inhibition of hypocotyls and rootlets of L . sativa to be numerically similar to that found in our work was tenfold higher (1000 ppm) [16]. In a study of allelopathic activity of Terminalia catappa fruit extracts biomonitored by L .…”

Peanut (Arachis hypogaea L.) is the fourth most consumed oleaginous plant in the world, producing seeds with high contents of lipids, proteins, vitamins, and carbohydrates. Biological activities of different extracts of this species have already been evaluated by many researchers, including antioxidant, antitumoral, and antibacterial. In this work, the allelopathic activity of extracts from different Brazilian peanut cultivars against lettuce (Lactuca sativa) and two weed plants (Commelina benghalensis and Ipomoea nil) was studied. Aerial parts, roots, seeds, and seed coats were used for the preparation of crude extracts. Seed extract partitioning was performed with n-hexane, dichloromethane, ethyl acetate, n-butanol, and aqueous residue. Germination and growth of hypocotyls and rootlets were evaluated after one and five days of incubation with plant extracts, respectively. Crude seed extract and its dichloromethanic partition displayed highest allelopathic activity. These results contribute for the study of new potential natural herbicides.

“…Results in this part showed that EO inhibits both the percentage and rate of germination in the evaluated weeds. It has been reported that both of this indices are important in weeds control management (Silva et al, 2013). In general, disruption of mitochondrial respiration (Podestá and Plaxton, 1994) and oxidative pentose phosphate pathway (OPPP) (Muscolo et al, 2001) are main reported reasons of phytochemicals in the prevention of seed germination.…”

“…Para o TME, as maiores concentrações do extrato, retardaram a emergência das plântulas, quando utilizados extratos de frutos de café, Silva et al (2013) averiguaram que o acréscimo das concentrações do extrato propiciou redução no TME das plântulas de repolho e alface, contrário ao que foi verificado nesse trabalho. Quanto ao IVE, observou-se que quando utilizadas concentrações maiores houve redução do número de plântulas emersas por dia (Figura 1).…”

RESUMOObjetivou-se identificar uma possível influência alelopática das sementes de Leucaena leococephala no estabelecimento de plântulas de feijão fava. As sementes da espécie florestal foram colhidas na cidade de Serra Talhada -PE. Foram utilizadas a partir do extrato bruto (100%) as diluições de 10; 25; 50 e 75%, além do controle (água destilada). Foi utilizado o delineamento estatístico inteiramente casualizado (DIC) com seis tratamentos e cinco repetições. Os dados foram sujeitos à análise de variância (teste F), quando verificada diferença significativa empregouse a análise de regressão. Foram avaliados parâmetros relacionados à emergência e ao estabelecimento das plântulas. As distintas diluições do extrato aquoso de sementes de leucena não interferiram na formação de plântulas normais de feijão fava, já com relação à velocidade do processo de emergência houve redução com o acréscimo das diluições. Na medida em que houve o acréscimo das diluições, ocorreu redução no tamanho e na matéria seca das plântulas. Logo, não é recomendado a utilização dessas duas espécies em um programa de sistema agroflorestal.

ON THE ESTABLISHMENT OF SEEDS OF Phaseolus lunatus L.ABSTRACT The objective of this study was to identify a possible allelopathic influence of Leucaena leococephala seeds in the establishment of fava bean seedlings. As seeds of the forest species were harvested in the city of Serra Talhada -PE. A crude extract (100%) was obtained as dilutions of 10; 25; 50 and 75%, in addition to the control (distilled water). A completely randomized design with six treatments and five replications was used. Data are subjected to analysis of variance (F test), when the difference in terms of regression analysis is verified. There are two points of view for
