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 …

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 …

Background Xylem, the most abundant tissue on Earth, is responsible for lateral growth in
plants. Typical xylem has a radial system composed of ray parenchyma cells and an axial …

This account presents information on all aspects of the biology of Fraxinus excelsior L.(Ash)
that are relevant to understanding its ecological characteristics and behaviour. The main …

Stem photosynthesis can contribute significantly to woody plant carbon balance, particularly
in times when leaves are absent or in 'open'crowns with sufficient light penetration. We …

Abstract Background and Aims Studies have indicated that plant stomatal conductance (gs)
decreases in response to elevated atmospheric CO2, a phenomenon of significance for the …

The oxygen stable isotope composition of plant organic matter (OM)(particularly of wood and
cellulose in the tree ring archive) is valuable in studies of plant–climate interaction, but there …

Reassimilation of internal CO 2 via woody tissue photosynthesis has a substantial effect on
tree carbon income and wood production. However, little is known about its role in xylem …

Drought-induced tree stress has gained increasing interest because of the recent coupling
between forest decline and global change associated droughts (Allen et al., 2010; Anderegg …

Key message Woody tissue photosynthesis might play a key role in maintaining plant
carbon economy and hydraulic function under unfavourable conditions such as drought …
