Alleviation of salinity stress on Vicia faba L. plants via seed priming with melatonin

Melatonin is an environmentally friendly-molecule with a potent free radical scavenger and antioxidant capacity. Two pot experiments were conducted during two successive winter seasons (2011/2012 and 2012/2013) at the wire-house of the National Research Centre, Dokki, Cairo, Egypt to study the poten...

description Melatonin is an environmentally friendly-molecule with a potent free radical scavenger and antioxidant capacity. Two pot experiments were conducted during two successive winter seasons (2011/2012 and 2012/2013) at the wire-house of the National Research Centre, Dokki, Cairo, Egypt to study the potentiality of melatonin (100 mM and 500 mM) in alleviating the harmful effect of diluted sea water at a relatively low and high concentrations (3.85 dS/m and 7.69 dS/m, respectively) on the performance of faba bean plant. The results revealed that irrigation of faba bean plants with diluted sea water reduced growth parameters (plant height, leaves number/plant, fresh and dry weights /plant), relative water content (RWC), photosynthetic pigments (chlorophylls a, b and carotenoids), indole acetic acid, total carbohydrate, K+,Ca+2, as well as the ratios of K+/Na+ and Ca+2/Na+ .Thiswasaccompanied by significant increases in phenolic content, compatible solutes (total soluble carbohydrate, free amino acids, proline), Na+ and Cl- , relative to the control plants (untreated plants). On the other hand, melatonin treatments improved growth parameters, RWC, photosynthetic pigments, total carbohydrate, total phenolic content, indole acetic acid, K+,Ca+2 as well as K+/Na+ and Ca+2/Na+ ratios, either in the plants irrigated with tap water or with diluted sea water, as compared with corresponding controls. Meanwhile, melatonin treatments reduced the levels of compatible solutes, as well as Na+ and Cl-  contents, relative to those of corresponding controls. Salinity stress and/ or melatonin treatments induced the production of new protein bands that did not occur in the control plants. Melatonin at 500 mM had a more pronounced effect in alleviating the adverse effects of the two salinity levels under study on the performance of faba bean plants than 100 mM melatonin.

Dos experimentos en materas fueron realizados en dos inviernos consecutivos (2011/2012 y 2012/2013) en instalaciones del Centro Nacional de Investigaciones, Dokki, Cairo, Egipto, para estudiar el potencial de la melatonina (100 mM and 500 mM) para disminuir los efectos nocivos del agua de mar diluida a concentraciones relativamente bajas y altas (3,85 dS/m and 7,69 dS/m, respectivamente). Los resultados mostraron que la irrigación de plantas de haba con agua de mar diluida reduce los parámetros de crecimiento (altura de la planta, número de hojas/planta, peso fresco y seco de la planta), el contenido relativo de agua (RWC), los pigmentos fotosintéticos (clorofilas a, b y carotenoides), el ácido indo lacético, los carbohidratos totales, K+ , Ca+2, al igual que las relaciones K+ /Na+ y Ca2+/Na+ . Esto fue acompañado por un incremento significativo en el contenido de fenoles, solutos compatibles (carbohidratos solubles totales, aminoácidos libres, prolina), Na+ y Cl- en comparación con las plantas control (plantas no tratadas). De otro lado, los tratamientos con melatonina mejoraron los parámetros de crecimiento, RWC, los pigmentos fotosintéticos, carbohidratos totales, contenido fenólico total, ácido indo acético, K+ ,Ca+2 al igual que las relaciones K+ /Na+ y Ca+2/ Na+ , tanto en las plantas irrigadas con agua dulce de la llave como en las irrigadas con agua de mar diluida en comparación con los controles correspondientes. De otro lado, los tratamientos con melatonina redujeron los niveles de solutos compatibles, al igual que los contenidos de Na+ y Cl- , en comparación con los controles. El estrés por salinidad y/o los tratamientos con melatonina indujeron la producción de nuevas bandas de proteínas que no estuvieron presentes en las plantas control. El tratamiento de melatonina 500 mM tuvo un efecto más pronunciado que el tratamiento de 100 mM en disminuir los efectos adversos de los dos niveles de salinidad estudiados sobre el comportamiento de las plantas de habaapplication/pdfspaUniversidad Nacional de Colombia - Sede Bogotá - Faculdad de Ciencias - Departamento de Biologíahttps://revistas.unal.edu.co/index.php/actabiol/article/view/43291Universidad Nacional de Colombia Revistas electrónicas UN Acta Biológica ColombianaActa Biológica ColombianaDawood, Mona Gergis (2015) Alleviation of salinity stress on Vicia faba L. plants via seed priming with melatonin.
