This study was undertaken to determine the influence of different treatments of temperature, photoperiod, gibberellic acid, and kinetin on the flowering responses of certain biennial species of the Umbelliferae. Seven species were selected for study, namely: carrots, wild carrots, parsnips, wild parsnips, poison hemlock, celery, and parsley.
