Comportamento de sementes de rúcula (Eruca vesicaria) expostas ao extrato aquoso de picão preto (Bidens pilosa)

Abstract

Allelopathic effects, are effects caused by substances released by plants acting positively or negatively from one plant over another, this effect is gaining more and more attention in the agronomic area due to the fact that the synthesis of substances with negative allelopathic characteristics has the ability to cause great damage to the crops since many of these substances interfere in the germination of the undesirable crops, so the objective of this work was to evaluate the allelopathic capacity of the aqueous extract of black prick on the germination of arugula seeds, in different concentrations. For the test, 25 seeds were distributed in a gerbox box, subjecting them to concentrations of 25% 50% 75% 100% extract, the extract was formulated from the mixture of dry ground plants and subsequently mixed in distilled water. distilled water is used. The test aimed to measure the effects that the aqueous extract on the germination of arugula seeds concluded that concentrations above 25% have an inhibitory action on the germination of arugula seeds.
