Abstract

This study aimed to evaluate the growth and photosynthetic pigments of tamarind seedlings as a function of different wavelengths promoted by colored growing benches in various protected environments. The experiment was conducted in two protected environments: an agricultural greenhouse, covered with low density polyethylene film and aluminized thermal-reflective net (Aluminet®), which provided 50% shading under the film; and a roof, covered and closed at 45 degrees with black monofilament fabric, also providing 50% shading. In each environment, a completely randomized design was used, with five treatments and four replications: T1: control, with no material on the bench surface; T2: bench covered with glossy white laminate; T3: bench covered with glossy red laminate; T4: bench covered with glossy blue laminate and T5: bench covered with glossy yellow laminate. The different wavelengths were enhanced by the colors of the countertops, which were covered with glossy, reflective laminates (Fórmicas®). The growing bench covered with bright white reflective material had the highest reflectance. Using the bench covered with yellow reflective material increased the growth of tamarind seedlings in the growing environments. Using yellow, blue, and red reflective benches increased the concentration of photosynthetic pigments in tamarind seedlings in protected environments. It can be said that the different wavelengths promoted by colored benches bring promising results for the quality of tamarind seedlings, in which it can be observed that the laminates influenced the growth and production of photosynthetic pigments.
