Abstract

and loss of dry weight. Low temperatures especially increase the antioxidant defenses and decrease the chlorophyll content compared to the heat conditions. However, dry weight losses are higher when plants are grown under heat than under cold conditions, probably because of the inactivation of Rubisco and/or the associated enzymes. Both crops were more resilient to cold than to heat temperatures, the capitata group being more resistant.
