description Estimating photosynthetic pigments, such as chlorophylls, as well as the foliar nitrogen content is very important for the evaluation of the nutritional and physiological status of a plant. However, producers cannot easily carry out these estimations because they involve analyses in laboratories that are costly and time-consuming. The SPAD-502 total chlorophyll index meter is efficient at rapidly estimating total chlorophyll contents in situ, along with its relationship with the total nitrogen concentration in tissues. The objective of this research was to validate a non-destructive in situ method (SPAD) for use in place of destructive estimation methods for chlorophylls a, b and total, as well as the foliar nitrogen concentration in guava plants (Psidium guajaba L.), cv. Regional Roja, in three phenological stages under the conditions of the municipality of Vélez-Santander (Colombia). The data obtained with the SPAD-502 and the content of chlorophylls a, b and total were adjusted to a second-degree polynomial with correlation coefficients (r) greater than 0.91 for the three phenological stages, while the concentration of foliar nitrogen was adjusted to a linear type model with determination coefficients (R2) higher than 0.90, indicating a highly linear correlation between the non-destructive method and the destructive methods used in the present study.

El medidor de índice de clorofila total tipo SPAD-502 es un equipo que ha demostrado su eficiencia en cuanto a la estimación rápida de los contenidos totales de clorofila in situ, así también, su relación con la concentración del nitrógeno total en tejido. El objetivo de la investigación fue el de validar el método in situ, no destructivo (SPAD) frente a los métodos de estimación destructivos de clorofilas a, b y total, así como la concentración de nitrógeno en tejido foliar en plantas de guayaba (Psidium guajaba L.) cv. Regional Roja en tres estadios fenológicos, bajo condiciones del municipio de Velez-Santander (Colombia). Los datos obtenidos con el SPAD-502 y el contenido de clorofilas a, b y total, se ajustaron a un polinomio de segundo grado con coeficientes de correlaciones (r) mayores a 0,91, en los tres estadios fenológicos evaluados, mientras que la concentración de nitrógeno foliar se ajustó a un modelo de tipo lineal con coeficientes de determinación (R2) superior al 0,90, esto indica la existencia de una alta correlación lineal entre el método no destructivo y los métodos destructivos empleados en el presente estudio.application/pdfengengSociedad Colombiana de Ciencias Hortícolas-SCCH and Universidad Pedagógica y Tecnológica de Colombia-UPTChttps://revistas.uptc.edu.co/index.php/ciencias_horticolas/article/view/11341/9782Copyright (c) 2020 Revista Colombiana de Ciencias Hortícolashttps://creativecommons.org/licenses/by-nc/4.0/http://purl.org/coar/access_right/c_abf40http://purl.org/coar/access_right/c_abf2Revista Colombiana de Ciencias Hortícolas; Vol. 14 No. 1 (2020); 26-31Revista Colombiana de Ciencias Hortícolas; Vol. 14 Núm. 1 (2020); 26-31Revista Colombiana de Ciencias Hortícolas; Vol. 14 No 1 (2020); 26-31Revista Colombiana de Ciencias Hortícolas; V. 14 N. 1 (2020); 26-31Revista Colombiana de Ciencias Hortícolas; v. 14 n. 1 (2020); 26-312422-37192011-2173SPADPhotosynthetic pigmentsMineral nutritionPortable meterNutritional statusPlant nutritionNitrogenFruitSPADPigmentos fotosintéticosNutrición mineralMedidor portátilEstatus nutricionalNutrición vegetalNitrógenoFrutalesEstimation and correlation of chlorophyll and nitrogen contents in Psidium guajava L. with destructive and non-destructive methodsEstimación y correlación de contenidos de clorofilas y nitrógeno en Psidium guajava L. mediante métodos destructivos y no destructivosTextTextoinfo:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6539http://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/publishedVersionhttp://purl.org/coar/version/c_970fb48d4fbd8a123http://purl.org/coar/version/c_970fb48d4fbd8a85Colombia; Santander; VelezColombia; Santander; VélezGüiza-Castillo, Luisa-LilianaPinzón-Sandoval, Elberth-HernandoSerrano-Cely, Pablo-AntonioCely-Reyes, Germán Eduardo Serrano-Agudelo, Pablo-Cesar001/16936oai:repositorio.uptc.edu.co:001/169362025-07-18 11:48:08.848https://creativecommons.org/licenses/by-nc/4.0/metadata.onlyhttps://repositorio.uptc.edu.coRepositorio Institucional UPTCrepositorio.uptc@uptc.edu.co
