Abstract
Bush beans, Phaseolus vulgaris var. humilis, when subjected to either gaseous fluoride or solutions containing fluoride, have abnormal oxygen uptake when compared with similar plants not subjected to fluoride. Plants given gaseous fluoride for 24 hours prior to harvest consistently had greater oxygen uptake than their control counterparts. Plants given continuous fluoride from time of germination had, with the exception of a short period around the fifth day, greater oxygen uptake than their control plants. Between the fourth and sixth days, continuously fumigated plants had a lower oxygen uptake than the unfumigated control plants. There appeared to be little difference in respiration patterns between gaseous fluoride-mediated respiration and aqueous fluoride-mediated respiration. This physiological disturbance induced by fluoride which has been demonstrated is considered to be an example of ''invisible injury'', by classical definition.
