| description | Hop (Humulus lupulus L.) is a plant with economic importance due to its use in the brewing industry. The cones produced by the species contain the main substances responsible for the beer’s bitterness and aroma. Hop plants cultivation in Brazil is still incipient and information on efficient methods for its propagation in this context are scarce. The objective of the present study was to evaluate the effect of different leaf areas (two whole leaves, two leaves in half, one whole leaf, one leaf in half and without leaves) in herbaceous stem cuttings planted in environments with and without intermittent misting. The experiment was conducted in a greenhouse in Curitiba-PR, Brazil (25º25’40 “S and 49º16’23” W). After 30 days of planting, the survival, rooting, sprouting and leaf retention percentages, roots number, average roots length and roots and sprouts dry mass were evaluated. Cuttings with one or two whole leaves and two leaves in half in the misting environment showed the highest rooting percentages (between 90.0 and 97.5%). In the without misting environment, the highest values were observed in cuttings with one or two leaves in half and one whole leaf (between 62.5 and 72.5%). Leafless cuttings had low survival percentages (2.5% in both environments). Under intermittent misting conditions it is recommended to prepare stem cuttings with one or two whole leaves and, in the absence of control over the environment humidity, cuttings with one whole leaf are recommended. |

Lúpulo (Humulus lupulus L.) es una planta con una economía importante debido a su uso en la industria cervecera. Los conos producidos por esta especie contienen las principales sustancias responsables de la amargura y el aroma de la cerveza. El cultivo de plantas de lúpulo en Brasil es aún incipiente en la información y los métodos eficientes para su propagación son escasos en este contexto. El objetivo del presente estudio fue evaluar el efecto de las diferentes áreas de hoja (dos hojas enteras, dos hojas a la mitad, una hoja entera, una hoja a la mitad y estacas sin hojas) en estacas herbáceas plantadas en ambientes con y sin nebulización intermitente. El experimento fue conducido en un invernadero en la ciudad de Curitiba-PR, Brasil (25º25’40 “S y 49º16’23” W). Después de 30 días se evaluaron los porcentajes de supervivencia, enraizamiento, brotación y retención de hojas, número de raíces, longitud promedio de raíces y masa seca de raíces y brotes. Las estacas con una o dos hojas enteras y dos hojas a la mitad, bajo nebulización, mostraron los porcentajes de enraizamiento más altos (entre 90 y 97,5%). En el ambiente sin niebla, los valores más altos se observaron en los esquejes con una o dos hojas por la mitad y una hoja entera (entre 62,5 y 72,5%). Las estacas sin hojas tuvieron bajos porcentajes de supervivencia (2,5% en ambos ambientes). Bajo condiciones de neblina intermitente, se recomienda preparar esquejes de tallo con una o dos hojas enteras y, sin nebulización, se recomiendan esquejes con una hoja entera.
