Effect of thermal stress on biomass production of two cultivars of Brassica oleracea exposed to chilling (12 °C) and high (32 °C) temperatures. a. Fresh weight (g) of the aerial part of seedlings grown under cold and heat conditions. b. Dry weight (g) of the aerial part recorded after drying in a oven at 80 °C until constant weight. c. Percentage of dry weight. In all pannels bars denote the mean of 20 measurements ± SE. Mean values within each cultivar with different letters are signifficantly different (P < 0.05)
