Efecto de la calidad espectral sobre el desarrollo vegetal de Salvia splendens variedad Vista Red and White

Abstract

<p class="p1">Tres diferentes calidades de luz fueron analizadas sobre una especie ornamental de importancia económica y comercial: <span class="s1"><em>Salvia splendens </em></span>ó <em>Scarlet Sage </em>(variedad Vista Red &amp; White de PanAmerican Seeds©), mediante la utilización de tres distintas fuentes de luz artificial (azul tipo LED, púrpura tipo LED y fluorescente) para modificar el ambiente de crecimiento de cada una de ellas. La investigación abarcó el análisis de la duración de días a floración, la altura, el diámetro, número de brotes y valores SPAD. Estudios existentes acerca del efecto de la calidad espectral sobre el desarrollo vegetal demuestran que hay alteraciones significativas en variables fotomorfogénicas y de crecimiento vegetal. Por ejemplo en el peso seco de la planta, altura, longitud entrenudos, número de brotes, duración del periodo de floración, número de estomas por planta y cantidad de almidones y azúcares reductores. Sin embargo, en el estudio realizado se encontró que la calidad espectral proporcionada con luz suplementaria sólo tiene efecto en los días a floración, comparado con el tratamiento testigo, puesto que reduce en una semana la floración, pero, no hay diferencia entre los tres diferentes tratamientos con luz suplementaria. La demás variables analizadas (número de brotes, altura, diámetro promedio y valores SPAD) no tienen un efecto significativo por la calidad espectral utilizada (p&gt;0.05). El estudio fue realizado en el invernadero académico del Tecnológico de Monterrey, ubicado en Monterrey, Nuevo León, México; durante el periodo de Agosto-Diciembre, 2013. </p>
