Abstract

Quality seedlings can guarantee the establishment of a productive crop, and, at the same time, light quality makes it possible to increase photosynthetic pigments. This study evaluated plant pigments along with the growth of Guaraci Cumari do Pará ornamental pepper seedlings on different-colored benches that emitted specific wavelengths. The wavelengths appeared from different reflective colored laminates (reflective bright blue laminate, reflective bright red laminate, reflective bright white laminate, reflective bright yellow laminate, and a control treatment without reflective material) on growth benches considered as treatments. The treatments were in a completely randomized design with six replications. The white laminate increased the photosynthetic-active radiation inside the experimental environment by 16.6%. The blue laminate promoted quality in pepper seedlings similar to the control bench regarding growth parameters, such as seedling height, stem diameter, and dry matter. However, the seedlings in the control bench had a higher quality index. The wavelengths promoted by the blue, red, and yellow laminates increased the production of chlorophyll a (41, 49, and 44%), chlorophyll b (36, 34, and 31%), and total chlorophyll (39, 45, and 40%) in the Guaraci Cumari do Pará pepper seedlings compared to the control. The color of laminates on the cultivation benches reflected different levels of photosynthetic-active radiation, influencing the traits of photosynthetic pigments in the Guaraci Cumari do Pará pepper seedlings.
