YIELD, BIOCHEMISTRY AND ECOPHYSIOLOGY OF HYBRIDS TOMATO PLANTS GROWING DIFFERENT TYPES OF ENVIRONMENT
Solanum lycopersicum (L.); Protected cultivation; environment protected; Tropical horticulture; High temperature;
The use of protected cultivation systems for tomato plants has corroborated the agronomic viability of the crop, but plastic coverings and/or polycarbonate can bring a different dynamic regarding production in regions with humid tropical climate by interfering in the environmental conditions of cultivation for the species. The present study aims to analyze physiological and productive aspects of tomato hybrids of determined habit of the salad group influenced by protected cultivation environments covered with polycarbanate and agricultural film and open field, in summer cultivation in a transition region between Cerrado and Amazon, in Sinop /Mt. 'Thaise', 'Trucker' and 'DS0060' salad tomato hybrids were cultivated in a protected environment covered with agricultural film (FA) and another with polycarbonate (P) and under field conditions. The hybrids Thaise and Trucker showed high productivity 92.6 and 88.2 t ha-1 in the environment covered with polycarbonate, respectively. The fruits of the hybrid 'Thaíse' showed higher antioxidant activity.
