Root hair dimensions and surface/volume/weight ratios of roots with the aid of scanning electron microscopy

Summary

Scanning electron micrographs were used to determine dimensions of hairy roots and formulae were derived for estimation of root surface area and volume. The method proved suitable for the structurally-complex proteoid roots ofLeucadendron laureolum whose surface area was 10.6×that of equivalent ‘normal’ roots on a volume basis and 15.8×on a dry weight basis.
