Wheat plants were harvested and separated into individual leaves, stem and roots, enabling an analysis of whole-plant dark respiration (R dark). a A representative image of a tiller with the roots, stem and leaf positions labelled. Leaf position 1 refers to the oldest leaf and position 5 refers to the newest emerging leaf. b Individual leaf, stem and root R dark on a mass basis (Mass flux; plotted on the left-axis) and total flux basis (Total flux; plotted on the right-axis). c A pie diagram illustrating the partitioning of the total flux of R dark between leaves as a whole, the stem and roots. The total plant leaf, stem and root fresh masses (g) are provided, as well as the % flux of total R dark. Values are based on the mean ± SE of six biological and pot replicates
