The effect of pretreatment on zinc‐ and copper‐enriched media on subsequent tolerance of F. hygrometrica to these metals was tested in three individuals each from a tolerant and a nontolerant population. Some individuals showed a significant response to pretreatment and some did not, and those that did varied in both intensity and direction. In general, pretreatment affected protonemal growth more than stem production. Although pretreatment effects were demonstrated, genetic differences between individuals and populations were more important determinants of the level of tolerance.
