Exudation of sap was never observed to occur from stumps of detopped seedlings of loblolly pine or white spruce, but measurable exudation occurred from apical root segments, 4 to 8 centimeters long, which were removed from the root systems and observed individually.

Biogeochemistry of Adjacent Conifer and Alder‐Conifer Stands
Ecology, 1992To determine the long—term effect of alder on soil fertility, biogeochemical fluxes were measured and calculated for two pairs of adjacent, 55—yr—old stands dominated by conifers, primarily Douglas—fir (Pseudotsuga menziesii), and by conifers and nitrogen—fixing red alder (Alnus rubra).

The Hydraulic Architecture of Conifers
2015The water-conducting cells in the xylem of conifers are tracheids. Despite the fact that these conduits are limited in diameter and length, the tracheid-based xylem structure of conifers supports the largest and tallest trees. This is explicable in the light of highly conductive pits and the fact that a large fraction of conifer wood is occupied by ...

Resins are plant exudates of economic importance used by plants as defence. They flow out of resin ducts, open and long tube-like intercellular spaces lined by a layer of specialized parenchyma cells, called the epithelium, which secrete resin into the duct lumen.
