Cumulative plant water uptake (PWU) of 'Norstar' and 'Rose' (A), and in a separate experiment 'Arapahoe' and 'YTO-117' (B) plants, northern adapted genotypes compared to the reference FR cultivar Winoka after soil drying 2 and 6 wk at 2°C. PWU was determined from the same plants as described in Fig. 6, data was calculated from soil water removed by each plant and normalized to plant dry weight. Vertical lines in each bar indicate standard error of the mean.
