WebThese results (1) indicate that transport of photoassimilate occurs through the leptome of perennating rhizomes, (2) demonstrate that translocated carbon is subsequently utilized or stored, and (3) raise important questions about the significance of long distance transport in the life strategy of this complex clonal moss. Authors: WebPost-photosynthetic fractionation processes during translocation, storage and remobilization of photoassimilate are closely related to intra-annual sigma13C of tree rings, and understanding how these processes affect tree-ring sigma13C is therefore indispensable for improving the quality of climate reconstruction.
