Fig. 5. Percent deviation from cold stressed mean for carbon exchange rate (CER), SPAD value, quantum efficiency of Photosystem II (_PSII), stomatal conductance, dry weight (DW), root/shoot ratio, and days from 7- to 8-leaf stage the for five inbred lines with the highest CER (A) and the five inbred lines with the lowest CER (B). *Percent deviation from DW mean for CG81 was 67.5%. **Percent deviation from DW mean for W23 was 138.2%.
