Allocation and residence time of photosynthetic products in a boreal forest using a low‐level ¹⁴C pulse‐chase labeling technique

Abstract

Much of our understanding about how carbon (C) is allocated in plants comes from radiocarbon ( 14 C) pulse-chase labeling experiments. However, the large amounts of 14

Environmental forcing does not induce diel or synoptic variation in the carbon isotope content of forest soil respiration

“…These results suggest that natural abundance carbon isotope studies in C 3 ecosystems are not likely to be a generally useful tool for partitioning of soil respiration. We recommend that future isotopic studies focused on partitioning the components of soil respiration take advantage of recent major advances in isotopic labeling (Carbone et al, 2007;Epron et al, 2012;Högberg et al, 2008).…”

“…We recommend that future isotopic studies that seek to disentangle the components of soil respiration take advantage of powerful recent advances in isotopic labeling (Carbone et al, 2007;Epron et al, 2012;Högberg et al, 2008). Author contributions.…”

Nonstructural Carbon in Woody Plants

“…The majority of our knowledge of new assimilates in woody plants comes from isotopic work, primarily pulse and continuous labeling (with 13 C or 14 C). These studies revealed how much and on what timescales new assimilates are allocated to growth, respiration, defense, storage, and exudates by following the fate of individual atoms as they move through plants.…”

“…NSC pool sizes are typically estimated allometrically, and dynamics are inferred from the net changes in concentration or pool size (69). Carbon isotopes have also been used to date different NSC pools or to provide a more dynamic picture of how recent photosynthate is allocated (13,106).…”

Connecting silvan and lacustrine ecosystems: transport of carbon from forests to adjacent water bodies

“…Because higher plants need energy and carbon compounds not only in photosynthetic leaves but also in other parts such as the roots, the assimilated carbon must be transported inside plants and the allocation is divided into above-and belowground compartments (e.g. Carbone et al 2007). The aboveground parts can be further divided, for instance, into leaves, stems and bark, and belowground parts into coarse roots, fine roots and mycorrhizae (e.g.…”
