  1. 1 Mineral content (Cd, Cu, Fe, Mn, Zn) of low- and high-Cd near-isogenic lines of durum wheat (Triticum turgidum subsp. durum) at physiological grain maturity (42 d post-anthesis) expressed as a percentage of the whole-plant content. Plants were grown in chelator-buffered nutrient culture containing 0.5 μM Cd (0.014 nM free activity). Significant differences between near-isogenic lines as determined by F-test-protected Student’s t-test are indicated by * (P ≤ 0.05). The t-tests were computed only when the ANOVA of the complete data set (all harvests for each tissue) yielded significant NIL or NIL × harvest treatment effects. Numbers in parenthesis are SE (n = 4).
