Microclimate and photosynthetic and transpiration rates of tomato plants in different growth environments

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.
