dc.descriptionTwo tomato genotypes with different sensitivity to high temperatures (cv Amalia and the wild type Nagcarlang) were exposed to several stress conditions (450C-2 hour exposition, 450C-3 hour exposition and 250C as control). Gas exchange and chlorophyll fluorescence were determined as well as antioxidant response expressed by SOD and APX activities. Physiological and biochemical variables changed depending on the genotype and stress exposure time. Gas exchange was reduced by stress conditions (45oC-3 hours), while chlorophyll fluorescence was reduced since the first hours of imposed stress in cv Amalia. The variables evaluated might be useful to describe genotype tolerance to high temperatures.
