Effect of drought treatment on performance parameters and their correlation with the drought score rank.

Mean values for the performance parameters water use efficiency (WUE), chlorophyll fluorescence (PAM Yield) 18 days after the start of the treatment, fresh weight (FW) and dry weight (DW) of the shoot and the entire plant, and relative dry weight compared to the control. F indicates the effect of the factor condition or cultivar on performance parameters. Bold and italic print indicates a significant effect with p
