Short‐term variation in the isotopic composition of organic matter allocated from the leaves to the stem of Pinus sylvestris: effects of photosynthetic and postphotosynthetic carbon isotope fractionation (2006, background): “…that the d13C and d18O of water-soluble carbon in leaves or phloem are strongly dependent on ci/ca (or on proxies for this value) and on Gs, respectively (Brugnoli et al., 1988; Barbour & Farquhar, 2000; Barbour et al., 2000b; Cernusak et al., 2003; Keitel et al., 2003; Scartazza et al., 2004).”
Improving water use in crop production (2008, methodology): “More recently, the isotopic ratio of 18O to 16O has been used to indicate the transpiration conditions during C fixation (e.g. Farquhar et al. 1994; Yakir & Israeli 1995; Barbour et al. 2000).”
Mesophyll diffusion conductance to CO2: an unappreciated central player in photosynthesis. (2012, methodology): “From these models, a “scaled effective path length” ( Leff, the product of the actual distance and the scalin g factor) can be determined by comparing modeled enrichment at the s i e of evaporation with observed values [154-156].”
Environmental Factors Determining Carbon Isotope Discrimination and Yield in Durum Wheat under Mediterranean Conditions (2003, background): “A negative relationship between and either (2000) and Barbour et al. (2000).”
Stable oxygen isotope composition of plant tissue: a review. (2007, methodology): “Barbour et al. (2000b) suggested that because a rapid exchange is expected for triose phosphates, exported sucrose should be in full isotopic equilibrium with average leaf water.”
Physiological traits and cereal germplasm for sustainable agricultural systems (2007, background): “Rebetzke et al., 2003) and integrative traits such as carbon or oxygen isotopic composition also show promise (Barbour et al., 2000).”
Breeding for Yield Potential and Stress Adaptation in Cereals (2008, background): “Accordingly, Barbour et al. (2000) proposed the use of δ18O in plant matter as an integrative indicator of genetic differences in stomatal conductance in bread wheat and its application to drought conditions has been further assessed (Ferrio et al., 2007).”
Understanding plant responses to drought - from genes to the whole plant. (2003, background): “Comparisons of 18O and 13C isotopic compositions can thus aid our understanding of plant response to stress because the effects of stomatal conductance and photosynthetic capacity on changes in water use efficiency can be separated (Farquhar et al. 1998; Barbour et al. 2000).”
Plant breeding and drought in C3 cereals: what should we breed for? (2002, background): “Recently, the stable oxygen isotope composition (d18O) of ¯ag leaves has been found to be signi®cantly negatively correlated with gs, CTD and grain yield in this historic set of CIMMYT wheats for two of the three seasons studied (Barbour et al., 2000).”
