| description | Small containers used in seedlings production of tree species with different root architecture can result in serious constraints for root growth and unsuitable plant quality, with potential impacts on field performance. We compare responses of root morphology to changes in container size and shape in both deep-rooting (Acacia caven) and shallow-rooting (Baccharis linearis) species, both commonly used in active restoration plans in central Chile. For both species, seedlings were cultivated in four different PVC container-types varying in size (440 mL and 880 mL) and shape ([10, 20, 35, and 45] cm in length), and a control treatment that consists in the commonly container-type used in Chilean nurseries (440 mL black polyethylene bag). Seedlings were cultivated for one growing season under controlled conditions and a set of above- and belowground morphological parameters were evaluated. A second short experiment was performed afterwards to evaluate potential seedling quality through the root growth potential (RGP) test. Results showed that an increase in container volume differently affected morphological parameters of A. caven and B. linearis seedlings. The control treatment had high presence of spiral roots for the deep-rooting species, restricting normal root growth. For both species, elongated containers (>35 cm) produced seedlings with smaller shoots with longer root systems and without deformations in the taproot or main root. Elongated containers also restarted growth of new roots more deeply in the container as result of the RGP test. We concluded that contrasting root architecture of native species require different container size in nursery to promote an adequate root development and growth. |

El uso de contenedores pequeños en producción de especies arbóreas con diferente arquitectura radical puede generar serias restricciones para el crecimiento de las raíces y producir plantas de pobre calidad y bajo desempeño en campo. El objetivo del estudio fue comparar respuestas morfológicas radicales al cambiar el tamaño y la forma del contenedor en especies de enraizamiento profundo (Acacia caven) y superficial (Baccharis linearis), ambas de alto interés para la restauración activa en Chile central. Las plántulas fueron cultivadas en cuatro tipos de tubos de PVC, que variaban en tamaño (440 mL y 880 mL) y forma ([10, 20, 35 y 45] cm de longitud vertical), más el control definido por la bolsa negra tradicional de polietileno de 440 mL (contenedor tradicional). Las plántulas fueron cultivadas durante una temporada de crecimiento bajo condiciones controladas. Al final del periodo de estudio se evaluaron altura y diámetro de tallo, longitud de raíz principal o pivotante, biomasa de raíces laterales y relación biomasa aérea/radical. Posteriormente, se aplicó la prueba de potencial de crecimiento radical (PCR) a un conjunto de plántulas seleccionadas al azar. Los resultados mostraron que un incremento en el volumen del contenedor afectó de forma diferenciada los parámetros morfológicos de A. caven y B. linearis. Se observó un alto porcentaje de raíces en forma de espiral en la especie con raíz pivotante (A. caven) cultivada en contenedores tradicionales. En ambas especies, los contenedores alargados (>35 cm) produjeron plantas con vástagos más pequeños, raíces más largas, sin deformaciones y con mayor capacidad de recuperar el crecimiento de raíces nuevas en zonas profundas del contenedor. Este estudio concluye que especies arbóreas con diferente arquitectura radical requieren de contenedores diferentes durante la fase de producción en vivero para promover el adecuado desarrollo y crecimiento de raíces.
