Physiological and morphological features denote that salt stress in Stevia rebaudiana is based on nonstomatic instead of stomatic limitation

Stevia rebaudiana is a very widespread plant throughout the world, due to the production of diterpenic steviol glycosides, with high sweetening power, being up to 300 times sweeter than sugar at a concentration of 0.4% (w/v). In the Colombian Caribbean, research has focused on evaluating the adaptat...

description	Stevia rebaudiana is a very widespread plant throughout the world, due to the production of diterpenic steviol glycosides, with high sweetening power, being up to 300 times sweeter than sugar at a concentration of 0.4% (w/v). In the Colombian Caribbean, research has focused on evaluating the adaptation and management of commercial genotypes and experimental lines, however, their behavior against soil salinization is unknown. The objective of this research was to evaluate the response of some physiological and morphological characteristics of two promising genotypes against salt stress. The relationship between gas exchange, chlorophyll a fluorescence, and growth parameters was modulated as a function of the NaCl concentration. Although stomatal conductance and perspiration did not show a response to salt levels, the reduction in net photosynthesis as salinity increased was not associated with stomatal effects, but rather with a drop in the rate of electron transport, which articulates the absorption of light energy and its conversion into photoassimilates. Therefore, it could be inferred that salinity-stressed S. rebaudiana plants are more sensitive to non-stomatal limitation than to stomatal limitation.

En el Caribe colombiano la investigación se ha enfocado en evaluar la adaptación y manejo de genotipos comerciales y líneas experimentales, sin embargo, se desconoce su comportamiento frente a la salinización del suelo. El objetivo de esta investigación fue evaluar la respuesta de algunas características fisiológicas y morfológicas de dos genotipos prometedores, frente al estrés salino. La relación entre el intercambio de gases, la fluorescencia de la clorofila a y los parámetros de crecimiento se moduló en función de la concentración de NaCl. Aunque la conductancia estomática y la transpiración no mostraron una respuesta a los niveles de sal, la reducción de la fotosíntesis neta a medida que aumentaba la salinidad no se asoció con efectos estomáticos, sino con una caída en la tasa de transporte de electrones, que articula la absorción de la energía luminosa y su conversión en fotoasimilados. Por lo tanto, se podría inferir que las plantas de S. rebaudiana estresadas por salinidad son más sensibles a la limitación no estomática que a la limitación estomática.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/12928/10802Copyright (c) 2021 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_abf207http://purl.org/coar/access_right/c_abf2Revista Colombiana de Ciencias Hortícolas; Vol. 15 No. 3 (2021); e12928Revista Colombiana de Ciencias Hortícolas; Vol. 15 Núm. 3 (2021); e12928Revista Colombiana de Ciencias Hortícolas; Vol. 15 No 3 (2021); e12928Revista Colombiana de Ciencias Hortícolas; V. 15 N. 3 (2021); e12928Revista Colombiana de Ciencias Hortícolas; v. 15 n. 3 (2021); e129282422-37192011-2173Biomass distributionDisruption between energy input and photosynthesisGas exchangeSalinityStomatal conductancePlant physiologyProducción de biomasa vegetalEquilibrio entre la captura de energía y la fotosíntesisIntercambio de gasesSalinidadConductancia estomáticaFisiología vegetalPhysiological and morphological features denote that salt stress in Stevia rebaudiana is based on nonstomatic instead of stomatic limitationCaracterísticas fisiológicas y morfológicas indican que el estrés salino en stevia está basado en limitaciones no estomáticasTextTextoinfo:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6706http://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/publishedVersionhttp://purl.org/coar/version/c_970fb48d4fbd8a290http://purl.org/coar/version/c_970fb48d4fbd8a85Colombia; Cordoba; MonteriaColombia; Cordoba; MonteriaCastillejo-Morales, AngelaJarma-Orozco, AlfredoPompelli, Marcelo F.001/16976oai:repositorio.uptc.edu.co:001/169762025-07-18 11:49:07.192https://creativecommons.org/licenses/by-nc/4.0/metadata.onlyhttps://repositorio.uptc.edu.coRepositorio Institucional UPTCrepositorio.uptc@uptc.edu.co
