Response of morphological and physiological traits to heat stress in two CfT lines (PS and SG). (A) Imaging of PS and SG exposed to heat stress treatments. (B) Comparison on physiological traits in two CfT lines. The values show the relative percentage change for each trait in response to heat stress. PS and SG represent Polish Spirit and Stolwijk Gold, respectively. Symbol “*”, “**”, and “***” represent significant levels at P < 0.05, 0.01, and 0.001, respectively, based on student-t test. Each bar data is the average of 6 replicates ±SE.
