The terrestrial carbon (C) cycle has received increasing interest over the past few decades,
however, there is still a lack of understanding of the fate of newly assimilated C allocated …

In addition to the green leaves, commonly considered as the primary sources of
photosynthate production, higher plants can potentially use almost all vegetative and …

Although some CO2 released by respiring cells in tree stems diffuses directly to the
atmosphere, on a daily basis 15–55% can remain within the tree. High concentrations of …

Below the outer peridermal or rhytidomal layers, most stems of woody plants possess
greenish tissues. These chlorophyll-containing tissues (the chlorenchymes) within the stems …

We measured oxygen isotope ratios (δ18O) of xylem sap, phloem sap, leaves, wood and
bark of Eucalyptus globulus Labill. growing in southwestern Australia. Carbon isotope ratios …

In this review, I first address the basics of gas exchange, water‐use efficiency and carbon
isotope discrimination in C3 plant canopies. I then present a case study of water‐use …

Upward transport of CO 2 via the transpiration stream from belowground to aboveground
tissues occurs in tree stems. Despite potentially important implications for our understanding …

In many plant species that remain leafless part of the year, CO 2 fixation occurring in green
stems represents an important carbon gain. Traditionally, a distinction has been made …

Temperature and light responses of CO2 efflux of Fagus sylvatica (beech) current‐year
stems were measured for 1 yr to estimate their annual carbon balance.• Gas exchanges …

Respiration consumes a large portion of annual gross primary productivity in forest
ecosystems and is dominated by belowground metabolism. Here, we present evidence of a …
