Abstract

Root research can benefit under many circumstances
from determination of the % fraction of root volume occupied by air (root porosity). Root
porosity provides an indication of root reaction or adaptability to environments with insufficient
oxygen availability. Three primary approaches have been used for root porosity determinations:
cross-sectional ratios, pycnometry, and dynamic gas displacement. These three methods are
explained and their relative advantages and disadvantages discussed.
