Do pathways of water movement and leaf anatomical dimensions allow development of gradients in H218O between veins and the sites of evaporation within leaves

Abstract

The oxygen isotope enrichment of bulk leaf water (ΔL) is often observed to be poorly predicted by the Craig-Gordon-type models developed for evaporative enrichment from a body of water (Δe). The discrepancy between ΔL and Δe may be explained by gradie Show more
