Ecological Section Ross, Sonya [1], Rice, Stanley [2]. Germination of Phacelia strictiflora is enhanced by smoke. Phacelia strictiflora is a wildflower that blooms abundantly after large fires in the cross-timbers forest of Oklahoma. It blooms only rarely at other times. We hypothesized that the seeds of P. strictiflora required exposure to smoke chemicals in order to germinate. In our experiment, the seeds germinated best in dilute smoke solution. Of several hundred seeds, only one seed germinated without exposure to smoke chemicals. When we replicated the experiment, however, a number of seeds germinated without exposure to smoke chemicals; but exposure to dilute smoke chemicals nevertheless stimulated germination relative to the controls. We therefore modified our hypothesis to state that germination of P. strictiflora seeds is enhanced by exposure to smoke chemicals. Broader Impacts:
