| description | Under natural conditions, the environmental light of plants varies spatially and temporally in terms of quality, quantity and duration. Reduction in light quantity affects numerous aspects of plant development. Many of these effects are related to the reduction in photosynthesis and consequential changes in sugar availability. The most studied responses are those of the induction of flowering and the elongation of stems and petioles. The effect of shading prior to cut of flowers in sea lavender plants cv. Blue stream on number of leaves and harvested flowers, the leaf specific weight and the flower stem length were evaluated. Plants grew under greenhouse conditions in Guasca (Colombia). For shading, black nets of 47 and 80% light reduction 1.5 m over plants were deployed. Control plants grew without a net over. Results showed reduction by all evaluated parameters through nets in comparison to control plants, but the stem length was more negatively influenced by shading. Flower stems were 36.5 and 49.0% shorter in comparison to those harvested in control plants under nets of 47 and 80% of light reduction, respectively, affecting strongly the flower quality for exportation. Results suggested high sensibility of sea lavender plants for light reduction. |

Bajo condiciones naturales, la luz ambiental disponible para las plantas varía espacial y temporalmente en términos de calidad, cantidad y duración. La reducción en la cantidad de luz afecta numerosos aspectos del desarrollo vegetal. Muchos de esos efectos están relacionados con la reducción en la fotosíntesis, con sus consecuentes cambios en la disponibilidad de azucares. Las respuestas más estudiadas al respecto son la inducción de la floración y la elongación de tallos y pecíolos. Se evaluó el efecto de la sombra antes del corte de las flores en plantas de limonio cv. Bluestream sobre el número de hojas y de flores cosechadas, el peso específico de las hojas y la longitud del tallo de las flores. Las plantas se desarrollaron bajo invernadero en Guasca (Colombia). Para inducir el sombreado, se desplegaron mallas polisombra de 47 y 80% de reducción de luz, 1,5 m por encima de las plantas. Las plantas control crecieron sin red por encima. Los resultados mostraron reducción, mediante la red, en todos los parámetros evaluados, en comparación con las plantas control, pero la longitud del tallo de la flor fue influenciada negativamente en mayor grado por la sombra. Los tallos florales fueron 36,5 y 49,0% más cortos que aquellos cosechados las plantas control bajo las mallas de 47 y 80% de reducción de luz, respectivamente, afectando severamente la calidad de la flor para exportación. Los resultados sugieren una alta sensibilidad de las plantas de limonio a la reducción de la luz.
