Abstract
The image of a tangential microscope section is projected on to a surface on which two parallel lines are drawn at a known distance apart and at right angles to the long axis of the tracheids. The number of cell tips occurring between the lines in a predetermined number of contiguous cells is counted. Values are then substituted in the following relationship: Mean tracheid length=Number of cells × distance between lines/numbers of cell tips The method is faster than the usual maceration technique, but its greatest advantage is the accuracy with which samples can be located.Keywords
