Blogpost - Counting Leaf Hairs on Fast Plants for Selection Experiments

This blog post from the Wisconsin Fast Plants website describes the observation of plant hairs (trichomes) for conducting a selective breeding experiment (such as in AP Biology investigations). The number of hairs is variable in Fast Plants seed varieties, and selection for or against plant hairiness is heritable, with measureable gain/loss from selection in offspring generations. This post describes strategies for identifying and counting plant hairs, including instructions for use of free ImageJ software.
