Production of Crisp Head Lettuce Cultivars in Hydroponic System Under Red Pigmented Mesh

Abstract

This study aimed to evaluate the production of twelve crisp head lettuce cultivars (Solaris, SVR 2005, Vera, Vanda, Invicta, Cristal, Alcione, Caipira, Camila, Thais, Brida and Bruna) in a hydroponic cultivation system. The experiment was conducted in a protected environment under red screen (ChromatiNet® Leno). The characteristics analyzed were: total and commercial fresh mass, stem and root fresh mass, stem length and diameter and total number of leaves. All evaluated cultivars reached the commercial weight for the market in natura, with Brida and Bruna cultivars showing higher total and commercial fresh mass.
