Symptoms and growth components of feijoa (Acca sellowiana [O. Berg] Burret) plants in response to the missing elements N, P, and K

description	Plants often express deficiencies with visible abnormalities; however, it is necessary to obtain reliable information to make the proper diagnosis about the missing nutrients. Until now, research with this approach has not been carried out for crops such as feijoa (or pineapple guava). For this reason, the present investigation identified and described the symptoms produced in young feijoa plants due to poor fertilization of N, P, and K and its effect on some components of plant growth and development. To achieve this, different treatments were established: complete fertilization (control); complete fertilization -N; complete fertilization -P; complete fertilization -K; and one treatment with no element (negative control, H2O). We determined the symptoms associated with each deficiency by means of a photographic record and the description of the symptoms. Among these nutrients, N deficiency yielded the highest plant detriment, due to lower growth and a global pale green coloration, while -P plants showed foliar malformations and necrosis, -K plants exhibited the brown margin in old leaves, then turning necrotic, while young leaves showed a lack of turgor. Also, lack of N seriously affected apical growth, number of basal and apical shoots, and chlorophyll foliar content, while the -P and -K developed lower growth rate in the shoot than in the control. Such symptoms were registered after two months of treatment. This study indicated that the greatest affectation of the feijoa was due to a lack of nitrogen; and also P and K deficiencies showed symptoms and growth characteristics that were altered in the development of the plants.

Las plantas a menudo expresan las deficiencias con anomalías visibles; sin embargo, es necesario obtener información confiable para realizar un diagnóstico adecuado sobre el elemento nutritivo faltante. Hasta ahora, no se han realizado investigaciones con este enfoque para cultivos como feijoa. Por tal motivo, la presente investigación identificó y describió los síntomas que se producen en plantas jóvenes de feijoa debido a la deficiente fertilización en N, P y K y su efecto sobre algunos componentes del crecimiento y desarrollo de las plantas. Para lograrlo, se establecieron los siguientes tratamientos: fertilización completa (control); fertilización completa -N; fertilización completa -P; fertilización completa -K y un tratamiento sin ningún elemento (control negativo, H2O). Los síntomas asociados a cada deficiencia se determinaron mediante un registro fotográfico y la descripción de los síntomas. Entre estos nutrientes, la deficiencia de N produce el mayor detrimento de las plantas, debido a un menor crecimiento y una coloración verde pálida generalizada, mientras que las plantas -P mostraron malformaciones foliares y necrosis, las plantas -K comenzaron a exhibir un margen marrón en las hojas viejas y luego necróticas, mientras las hojas jóvenes expresaron falta de turgencia. Además, la falta de N afectó seriamente el crecimiento apical, el número de brotes basales y apicales y el contenido foliar de clorofila, mientras las plantas -P y -K desarrollaron brotes con menor tasa de crecimiento que el control. Estos síntomas se registraron después de dos meses de tratamiento. Este estudio muestra la mayor afectación de la feijoa por falta de nitrógeno, pero también las deficiencias de P y K generan síntomas y características de crecimiento alterados en el desarrollo de las plantas.
