Liming applications and the SPAD chlorophyll index and stomatal conductance in cocoa exposed to cadmium in the soil
Cadmium is a heavy metal that affects cell structures, such as walls and membranes, especially in the photosynthetic apparatus (PSII), chlorophylls, chloroplasts and stomata, producing losses in production quantity and quality. In addition, it is harmful to the health of humans and animals. The obje...

description |
Cadmium is a heavy metal that affects cell structures, such as walls and membranes, especially in the photosynthetic apparatus (PSII), chlorophylls, chloroplasts and stomata, producing losses in production quantity and quality. In addition, it is harmful to the health of humans and animals. The objective was to analyze the behavior of the relative chlorophyll index (SPAD units) and stomatal conductance in clone CCN-51 cacao plants every 45 days (45, 90, 135 and 180 days) after liming application. Four doses of a dolomite + agricultural gypsum mixture were applied, increasing Ca+2 saturation in the soil to 7, 8 and 9 cmolc kg-1. The control treatment did not have applications. The results indicated a reduction in SPAD units in the plants without liming, with high cadmium levels in the soil (3.3 mg kg-1), and there were no statistical differences in the other treatments, possibly because of edaphic factors such as pH, organic matter content and Al+3. The best stomatal conductance was observed with 7 cmolc kg-1 in the foliar gas exchange. Supersaturated liming applications efficiently reduce the losses in quality and quantity caused by the accumulation of cadmium in cacao plants. |

Además, es un agente potencialmente maligno para la salud de humanos y animales. El objetivo de este trabajo consistió en analizar el comportamiento del índice relativo de clorofilas (unidades SPAD) y la conductancia estomática en plantas de cacao clon CCN-51 con la frecuencia de 45 días (45, 90, 135 y 180 días) posterior a la aplicación de encalado. Se aplicaron cuatro dosis de la mezcla dolomita + yeso agrícola aumentando la saturación de Ca+2 en el suelo a 7, 8 y 9 cmolc kg-1 y el tratamiento control sin aplicación. Los resultados indican reducción de las unidades SPAD en plantas sin encalado con altos niveles de cadmio en el suelo (3.3 mg kg-1) y no se presentaron diferencias estadísticas con los demás tratamientos, posiblemente a la incidencia de factores edáficos como el pH, los contenidos de materia orgánica y Al+3. Los mejores resultados de conductancia estomática se observaron en 7 cmolc kg-1 en el intercambio gaseoso foliar. Las aplicaciones de materiales encalántes en sobresaturación pueden convertirse en una medida eficiente para disminuir pérdidas en calidad y cantidad ocasionadas por las acumulaciones de cadmio en cacao.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/14530/12327Copyright (c) 2022 Revista Colombiana de Ciencias Hortícolashttp://creativecommons.org/licenses/by-nc-sa/4.0https://creativecommons.org/licenses/by-nc/4.0/http://purl.org/coar/access_right/c_abf577http://purl.org/coar/access_right/c_abf2Revista Colombiana de Ciencias Hortícolas; Vol. 16 No. 2 (2022); e14530Revista Colombiana de Ciencias Hortícolas; Vol. 16 Núm. 2 (2022); e14530Revista Colombiana de Ciencias Hortícolas; Vol. 16 No 2 (2022); e14530Revista Colombiana de Ciencias Hortícolas; V. 16 N. 2 (2022); e14530Revista Colombiana de Ciencias Hortícolas; v. 16 n. 2 (2022); e145302422-37192011-2173Heavy metalsSoil amendmentsTranspirationPigmentsTheobroma cacao L.CocoaMetales pesadosEnmiendas del sueloTranspiraciónPigmentosTheobroma cacao L.CacaoLiming applications and the SPAD chlorophyll index and stomatal conductance in cocoa exposed to cadmium in the soilAplicaciones encalántes y el índice de clorofilas SPAD y la conductancia estomática de cacao expuesto a cadmio en el sueloTextTextoinfo:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_7076http://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/publishedVersionhttp://purl.org/coar/version/c_970fb48d4fbd8a660http://purl.org/coar/version/c_970fb48d4fbd8a85Colombia; Boyaca; OtancheColombia; Boyaca; OtancheSuárez-Parra, Karen VictoriaCastañeda-Serrano, Cristian SantiagoForero-Ulloa, Fabio EmilioAlmanza-Merchán, Pedro JoséSerrano-Agudelo, Pablo César001/17012oai:repositorio.uptc.edu.co:001/170122025-07-18 11:49:35.721https://creativecommons.org/licenses/by-nc/4.0/metadata.onlyhttps://repositorio.uptc.edu.coRepositorio Institucional UPTCrepositorio.uptc@uptc.edu.co |
