| The aim of the work was to evaluate the growth and productivity of lettuce cultivars cultivated in greenhouse with and without thermo-reflective screens. The experiment was conducted in greenhouse in Assis Chateaubriand, Paraná State. The experimental design was in a randomized block design with six replications and treatments arranged in a 2 x 4 factorial. The first factor consisted of culture environments (with and without thermo-reflective screens 50%) and the second of four cultivars of lettuce (Itapuã, Paola, Vera and Verônica).
