Abstract

The construction and use of a variable force penetrometer for measuring the woodiness of kale stems is described.

The force required to cause penetration of the probe through the xylem tissue was found to bear a close relationship to estimates of quality based on in vitro digestibility determinations, crude fibre content and visual assessment of lignification in stained transverse sections of stems.
