Abstract

The aim of this study was to estimate the microclimate and the photosynthetic and transpiration rates of tomato grown at open air plots (CA); in screenhouses with citrus insect-proof screen (RT); in plastic covered greenhouses without insect-proof screen (ST) and in plastic covered greenhouses with three types of insect-proof screen, anti-aphidian (AF), citrus (CI) and clarity (CL), in Itajaí, SC, in 2004. The protected cultivation with screens with smaller thickness provided greater leaves and air temperatures. Thirty-five days after planting
photosynthetic rates were greater in protected cultivation while transpiration rates were greater in protected cultivation with anti-aphidian and citrus screens.
