Oxygen isotope ratio of leaf and grain material correlates with stomatal conductance and grain yield in irrigated wheat.
Theory (Craig and Gordon 1965; Dongmann et al. 1974; Sternberg et al. 1986; Farquhar and Lloyd 1993) suggests that the oxygen isotope ratio (δ18O) of plant material should reflect the evaporative conditions under which the material was formed, so that di
