| description | Mexico is the country with the highest number of Quercus species worldwide (157). The oaks have great ecological importance and economic potential. However, their seeds and nursery propagation have been scarcely studied. The aim of this study was to investigate the effect of nut size and color, as well as shade, on germination of Quercus deserticola. The experiment was installed in a controlled environment chamber (25 °C/20 °C, with a photoperiod of 10 h of light). The experimental factors were nut size (small and large), color (light brown and dark brown), and shade (with and without 40% shade). The experimental design was completely randomized blocks, with the blocks nested into the shade factor. An analysis of variance with a mixed procedure and a Tukey means comparison were conducted, with the variables germinative capacity and germinative energy and a logistic model was constructed to estimate the probability of germination. There was a significant effect of seed size (p = 0.0067), seed color (p < 0.0001) and shade (p = 0.0078) on germinative capacity. The highest germinative capacity (100%) was for large seeds of dark brown color and under shade. The germinative energy (number of days to reach 70% of the germinative capacity) was affected by seed color (p < 0.0001) and by the interaction seed size*color (p = 0.0267). The highest germinative energy (11.5 days) was for large and dark brown colored seed. |

Los encinos tienen una gran importancia ecológica y potencial económico. No obstante, sus semillas y propagación han sido poco estudiadas. El objetivo del presente trabajo fue estudiar la influencia de tamaño y color de la nuez, así como de la sombra, en la capacidad y energía germinativas de Quercus deserticola. Para ello se instaló un experimento en cámara de ambiente controlado (25 °C/20 °C), con un fotoperiodo de 10 h luz. Los factores fueron tamaño de la nuez (chica y grande), color (café claro y café oscuro) y sombra (40%) (con y sin). El diseño experimental fue en bloques al azar, anidados dentro del factor sombra. Se condujo un análisis de varianza con un modelo mixto y una comparación de medias de Tukey, para las variables capacidad germinativa y energía germinativa, y se obtuvieron los parámetros de un modelo logístico para estimar la probabilidad de germinación. Se halló un efecto significativo de tamaño (p = 0.0067) y color (p < 0.0001) de la semilla, así como de la sombra (p = 0.0078) en la capacidad germinativa. La mayor capacidad germinativa, de 100%, se logró con semilla de nuez grande, café oscuro y con sombra. De acuerdo con el análisis de varianza, la energía germinativa (número de días para alcanzar 70% de la capacidad germinativa) fue influida por el color (p < 0.0001) y por la interacción tamaño*color (p = 0.0351). La mayor energía germinativa, con un valor de 11.5 días, se alcanzó con semilla de nuez grande y café oscura.
