Abstract Detail

Bioinformatic and Biometric Methods in Plant Morphology

Green, Walton [1].

Quantifying dicot leaf venation.

The reticulate venation that is characteristic of a dicot leaf has excited interest from systematists for more than a century, and from physiological and developmental botanists for decades. The tools of digital image acquisition and computer image analysis, however, are only now approaching the sophistication needed to quantify aspects of the venation network found in real leaves quickly, easily, and reliably enough to produce biologically meaningful data. Using some unpublished data collected in the 1980s by the late Leo Hickey, as well as more recent measurements, I will review some methodological issues that arise in trying to quantify a vein network, and propose criteria for comparing the strengths and weaknesses of automatic data collection and hand measurement.
