Cumulative ¹⁴C activity lost from root to solution 4.5 h (measured) and 20 h (estimated) after the end of the pulse feed to leaf 2 of intact and partially defoliated plants of wheat

Values represent means ± sem (n = 3). Significant differences (P < 0.05) as determined by two-tailed unpaired t test are indicated by different postscripts.
