Abstract
Se llevó a cabo un estudio con el objetivo de evaluar el potencial de crecimiento radicular (PCR) como una herramienta única para calificar las plantas de Quillaja saponaria producidas a raíz cubierta, provenientes de tres viveros diferentes. Para validar los resultados obtenidos, se realizó un ensayo en terreno con una duración de seis meses, durante el cual se midieron diversas variables morfológicas tanto al inicio como al final del experimento.
Los resultados mostraron que el PCR fue un buen indicador únicamente para el incremento relativo porcentual de la variable de diámetro a la altura del cuello en el ensayo en terreno. El PCR no fue un buen indicador del incremento relativo porcentual de la longitud de tallo ni de otras variables morfológicas evaluadas. Además, la comparación de los atributos indicó que el PCR no constituye un indicador confiable de los atributos morfológicos de las plantas en condiciones de terreno, lo que sugiere la necesidad de complementar su uso con otras variables para una evaluación más precisa.
A study was conducted to evaluate the root growth potential (RGP) as a unique tool for assessing container-grown Quillaja saponaria plants produced in three different nurseries. To validate the results, a six-month field trial was carried out, during which various morphological variables were measured at both the beginning and the end of the experiment. The results showed that RGP was a good indicator only for the relative percentage increase in the diameter at the root collar during the field trial. However, RGP was not a reliable indicator for the relative percentage increase in stem length or other evaluated morphological variables. Additionally, the comparison of attributes indicated that RGP is not a dependable predictor of morphological traits under field conditions, suggesting the need to complement its use with other variables for a more accurate assessment.
