Abiotic stress caused by foliar applications of boron to the yellow diploid potato (Solanum tuberosum, Group Phureja) cultivar Criolla Galeras
Foliar applications of boron (B) constitute a frequent practice in the fertilization of the yellow diploid potato and are generally done with excessive and empirical doses generating toxicities in crops. The effect of foliar applications of B at doses of 0, 0.5, 1.2, or 4 kg ha-1 was determined for...

| description | Foliar applications of boron (B) constitute a frequent practice in the fertilization of the yellow diploid potato and are generally done with excessive and empirical doses generating toxicities in crops. The effect of foliar applications of B at doses of 0, 0.5, 1.2, or 4 kg ha-1 was determined for physiological and metabolic variables and toxicity symptoms in the yellow diploid potato cultivar Criolla Galeras under greenhouse conditions using Na octaborate (20.5% B, 11% Na) or boric acid (17.5% B) as sources of B. Significant differences (P<0.05) were found between the sources and doses for dry matter (DW), leaf area (LA), proline content, and electrolyte leakage (ECh). The highest toxicity was observed for B applied as sodium octaborate at concentrations of 2 and 4 kg ha-1 B with a reduction of DM up to 40%, a decrease of LA up to 90%, a loss of 60% in ECh, and a significant increase in the concentration of proline (65 μmol/g fresh weight). The lower toxicity of boric acid at doses higher than 2 kg ha-1 B indicated that the octaborate Na presented synergism with B, which can result in a greater oxidative stress, causing instability of the membranes, necrosis and premature tissue death, as evidenced in the description of the visual symptoms. The doses of 0.5 and 1.0 kg ha-1 B for both sources resulted in positive responses in the DW and non-significant (P<0.05) differences with the control, associated with the levels of proline and ECh, which indicated a narrow range between the deficiency and toxicity of B for cv. Criolla Galeras, where the effect of the accompanying ion must be considered in the selection of the boron source. |

La aplicación foliar de boro (B) es una práctica frecuente en el manejo de la fertilización en papa amarilla diploide, generalmente, se realiza de manera excesiva y empírica generando toxicidades en el cultivo. Se determinó bajo condiciones de invernadero el efecto de la aplicación foliar de B en dosis de 0; 0,5; 1,2 y 4,0 kg ha-1, utilizando como fuentes octaborato de Na (20,5% B, 11% Na) o ácido bórico (17,5% B), sobre variables fisiológicas, metabólicas y síntomas de toxicidad en papa amarilla diploide cultivar Criolla Galeras. Se presentaron diferencias significativas (P<0,05) entre fuentes y dosis para materia seca (MS), área foliar (AF), contenido de prolina y pérdida de electrolitos (CEh). Se observó una mayor toxicidad por B cuando se aplicó octaborato de sodio en concentraciones de 2 y 4 kg ha-1 B con un detrimento para MS hasta del 40%, disminución del AF hasta del 90%, pérdida del 60% de CEh e incremento significativo en la concentración de prolina (65 µmol/g de peso fresco). La mayor toxicidad de ácido bórico a dosis mayores a 2 kg ha-1 B indicó que el Na proveniente de la fuente de octaborato creó un sinergismo con el B, lo cual puede incidir en un mayor estrés oxidativo, causando inestabilidad de membranas, necrosis y muerte prematura en tejidos como se evidenció en la descripción de la sintomatología visual. Las dosis de 0,5 y 1,0 kg ha-1 B para ambas fuentes resultaron en respuestas positivas en MS y no significativas (P<0,05) con el control, asociado a niveles de prolina y CEh, que comprueban el rango estrecho entre deficiencia y toxicidad para el cv. Criolla Galeras, donde se debe considerar el efecto del ion acompañante en la selección de la fuente.
