Abstract
The objective of this work was to evaluate the production of cherry tomatoes in protected environments composed of different photoselective screens. The work was conducted in June / July 2018. The treatments consist of different types of protected environments: open sky, black screen (mesh for 30% shade); white fabric (mesh for 20% shade); blue screen (mesh for 20% of shade) and red screen (mesh for 20% of shade). The experimental design was a randomized block with four replicates, ten plants per experimental plot. The following analyses were performed on cherry tomatoes: leaf number, stem diameter, shoot height, root length, total fresh matter, shoot fresh matter, fresh root matter, shoot dry matter, root, chlorophyll a and chlorophyll b. The black shading, white photoselective, blue photoselective and red photoselective screens did not influence the number of leaves, stem diameter, shoot height, root length, total fresh matter, fresh shoot matter, aerial shoot dry matter, root dry matter, chlorophyll a and chlorophyll b. The red photoselective screen showed superiority in the fresh matter of the root of the other treatments.
