Allelopathic potential of leachates of cover crops and weeds on young vines
Interactions between vines and herbaceous species may involve competition for resources and allelopathy. It is presumed that certain cover crops and weeds have allelopathic effects on the growth of grapevines. The objectives were: a) to evaluate the effect of leachate from irrigation of different co...

| description | Interactions between vines and herbaceous species may involve competition for resources and allelopathy. It is presumed that certain cover crops and weeds have allelopathic effects on the growth of grapevines. The objectives were: a) to evaluate the effect of leachate from irrigation of different cover crops on vines and b) to determine its inhibitory effect on seed germination. Greenhouse and field experiments were conducted with cover crops and potted vines. Eleven leachates from different green covers and a bare soil control were tested with a randomized design and five replicates. The vegetative and productive expression of the vines was evaluated. Seed germination tests were conducted using leachate from irrigation and different concentrations of the aqueous solution. Adverse effects were not detected in the vegetative growth, the grape production in young vines or the germination of other plant species. The pot trial showed that there is an interaction between cover crops and soil, whereby the balance of nutrients is altered depending on the species. This balance can positively or negatively affect the growth of the vines. |

Se presume que determinados cultivos de cobertura y malezas poseen efectos alelopáticos sobre el crecimiento de las cepas. Los objetivos del trabajo fueron: a) evaluar el efecto de los lixiviados de riego de diversas coberturas vegetales sobre plantas de vid y b) determinar su efecto inhibitorio sobre la germinación de semillas. Se efectuaron experimentaciones de campo e invernadero, con cultivos de cobertura y vides en macetas. Se utilizaron 11 lixiviados de diferentes cubiertas vegetales y un testigo con suelo descubierto, con un diseño completamente al azar y cinco repeticiones. Se evaluó expresión vegetativa y productiva de las vides. Se realizaron pruebas de germinación sobre semillas, utilizando lixiviados del riego y diferentes concentraciones de la solución acuosa. No se detectó efecto negativo en el crecimiento vegetativo ni en la producción de uva en plantas jóvenes de vid, ni tampoco en la germinación de otras especies vegetales. El ensayo en macetas evidenció que existe una interacción entre las coberturas y el suelo, mediante la cual el balance de nutrientes es alterado según la especie, y puede afectar positiva o negativamente el crecimiento de las vides.
