| description | The algarrobo blanco tree (Prosopis alba), a tree species used in afforestation in semi-arid zones in Argentina, requires greater knowledge of its growth phases in the nursery to adjust irrigation, fertilization, and plant production time programs, in order to produce quality plants that ensure better responses in the field. For this, in this study, different durations in the hardening phase and their influence on the morphological attributes of quality in Prosopis alba Griseb plants were evaluated. The recorded variables were diameter at neck height (DAC), total height (Ht), root dry weight (PSR) and aerial dry weight (PSA); and the morphological indices: Dickson's index (ICD), aerial and root dry weight ratio (PSA/PSR) and slenderness index (IE). To determine the effects of the treatments tested, longitudinal measurements were made on the DAC and Ht evaluated by repeated means analysis of the mixed linear model’s module. The other parameters were evaluated by analysis of variance in the measurement 105 days after sowing. The results indicated that the treatment with duration of 60 days in the hardening phase presented the morphological parameters with the best quality. It is concluded that a longer duration in the hardening phase generated better morphological attributes, mainly 60% to 140% more root biomass and in the ICD a value 90% to 140% higher with respect to the other treatments. |

El algarrobo blanco (Prosopis alba), especie arbórea utilizada en forestaciones en zonas semiáridas en Argentina, requiere de un mayor conocimiento de sus fases de crecimiento en vivero para ajustar programas de riego, fertilización y época de producción de plantas, con el fin de producir plantas de calidad que aseguren mejores respuestas en campo. Para ello, en este estudio se evaluaron diferentes duraciones en la fase de endurecimiento y su influencia sobre los atributos morfológicos de calidad en plantas de Prosopis alba Griseb. Las variables registradas fueron: diámetro a la altura de cuello (DAC), altura total (Ht), peso seco radical (PSR) y aéreo (PSA); y los índices morfológicos: índice de Dickson (ICD), relación entre peso seco aéreo y radical (PSA/PSR) e índice de esbeltez (IE). Para determinar los efectos de los tratamientos ensayados, se efectuaron mediciones longitudinales en las variables DAC y Ht evaluadas mediante análisis de medias repetidas del módulo de modelos lineales mixtos. Los demás parámetros fueron evaluados mediante análisis de varianza en la medición a los 105 días de la siembra. Los resultados indicaron que el tratamiento con una duración de 60 días en la fase de endurecimiento presentó los mejores parámetros morfológicos de calidad. Se concluye que una mayor duración en la fase de endurecimiento generó mejores atributos morfológicos, principalmente 60% a 140% más de biomasa radicular y en el ICD un valor 90% a 140% más alto con respecto a los demás tratamientos.
