Foliage water content (FWC) of 'Norstar' and 'Rose' (A), and in a separate experiment 'Arapahoe' and 'YTO-117' (B), northern adapted genotypes compared to the reference FR cultivar (Winoka) after soil drying 2 and 6 wk at 2°C. Five-day seedlings were grown 23 d in the greenhouse at 25°C before cold treatment. Immediately prior to 2°C exposure, soil water content was adjusted to a soil matric potential of -0.004 MPa; no additional water was supplied. Each FWC value is a mean from 3 plants. Vertical lines in each bar indicate standard error of the mean.
