During the growing season, the cambium of conifer trees produces successive rows of xylem cells, known as tracheids. Current knowledge on this process mainly stems from xylogenesis monitoring spanning a few years. In...
Plants growing under elevated atmospheric CO2 concentrations often have reduced stomatal conductance and subsequently increased leaf temperature. Šigut et al. find that this is indeed the case for broadleaved Fagus...
Results indicate that not all gases dissolved in the xylem sap are trapped within the ice in the stem of Scots pine and Norway spruce, during freezing.
