| description | Nutrient deficiency symptoms are widely used to determine the nutrient demands of a crop and to clarify nutritional disorders, especially when they are nutrient specific. Until now, a calcium (Ca), magnesium (Mg) and boron (B) deficiency experiment has not been carried out on feijoa, and diagnostic symptoms have not been described. For this reason, 9-months-old ‘Quimba’ feijoa plants were studied using the missing nutrient method. A modified Hoagland and Arnon solution was applied for each treatment, leaving out one element in each treatment. The treatments were: (1) complete fertilization (control); (2) complete fertilization -Ca; (3) complete fertilization -Mg; (4) complete fertilization -B; and (5) without fertilization (negative control). Deficiency symptoms in the plants were described, and photographic records were made. The Ca deficiency was noted early in the shoot tips and later in fully-expanded, young leaves. The Mg-deficiency was observed in older and fully-expanded leaves, mainly as interveinal chlorosis, while the B deficiency generated a variety of symptoms, interveinal and total chlorosis in fully and not fully-expanded leaves and a mosaic of symptoms in adult leaves. For the growth components, the Mg deficiency reduced the number of apical shoots, while the Ca- and Mg-deficiencies reduced the seedling growth rate significantly. For future experiments, the authors suggest an experiment period longer than 102 d to achieve more conclusive results. |

Los síntomas de deficiencia de nutrientes se utilizan ampliamente para determinar las demandas de nutrientes de un cultivo y aclarar los desórdenes nutricionales, en particular cuando son específicos de un determinado elemento nutritivo. Hasta el momento no se ha realizado un experimento de deficiencias de calcio (Ca), magnesio (Mg) y boro (B) en feijoa y descritos síntomas diagnosticados. Por esta razón, se estudiaron plantas de feijoa ‘Quimba’ de 9 meses de edad utilizando el método del nutriente faltante. Se aplicó una solución modificada de Hoagland y Arnon, suprimiendo un elemento en cada tratamiento. Los tratamientos fueron: (1) fertilización completa (testigo); (2) fertilización completa -Ca; (3) fertilización completa -Mg; (4) fertilización completa -B; (5) sin fertilización (control negativo). Se describieron los síntomas de deficiencia diagnosticados en las plantas y se hicieron registros fotográficos. La deficiencia de Ca se notó temprano en los ápices de los brotes y luego en las hojas jóvenes completamente expandidas. La falta de Mg se presentó en hojas más viejas y completamente expandidas principalmente como clorosis intervenal, mientras que la deficiencia de B generó una variedad de síntomas, clorosis intervenal y total en hojas completamente y no completamente expandidas, y un mosaico de síntomas en hojas adultas. Con respecto a los componentes de crecimiento, la deficiencia de Mg redujo el número de brotes apicales, mientras que las plantas deficientes de Ca y Mg redujeron significativamente la tasa de crecimiento de las plántulas. Para experimentos futuros, los autores sugieren un período experimental más largo que 102 d para lograr resultados más concluyentes.
