Resumo: | The aim of this study was to evaluate the photosynthetic and transpiration rates in differentlayers of tomato cultivars. Photosynthetic rate, transpiration, stomata conductance, internal CO2 concentration, leaf temperature, air temperature and photosynthetically active radiation were evaluated in the beginning of the harvest. There were no differences among cultivars for all parameters. Photosynthetic rates were higher inthe upper layers. However, the photosynthetic rates in all layers were above the light compensation point, contributing with carbohydrates for the growth and development of the fruits. The transpiration rates were alsohigher in the upper layers. The leaf temperature was higher in the downer layers. |

O presente trabalho teve por objetivo avaliar as taxas fotossintéticas e transpiratórias em cultivares de tomate nos estratos superior, médio e inferior do dossel. As taxas fotossintéticas e transpiratórias, a condutância estomática, a concentração interna de CO2, a temperatura da folha, a temperatura do ar e a radiação fotossinteticamente ativa incidente foram avaliadas no início da colheita. Não houve diferenças expressivas entre as cultivares com relação às variáveis estudadas. As taxas fotossintéticas no início da colheita foram maiores nos estratos superiores do dossel. Todavia, em todos os estratos as taxas fotossintéticas estavam acima do ponto de compensação luminosa, contribuindo com fotoassimilados para o crescimento e desenvolvimentodos frutos. As taxas transpiratórias também foram maiores nos estratos superiores. Já a temperatura foliar foi maior nos estratos inferiores.
