The response of bean fruiting to HF fumigation was investigated in a series of experiments. The plants were exposed to various concentrations of HF, either for 7 to 14 days at different times relative to flowering or continuously from seeding to harvest. To accentuate the response to HF, the plants were grown with with low calcium (40 ppM) nutrient solution in most studies. Hydrogen fluoride treatments averaging up to 8.0 ..mu..g F/m/sup 3/ for 9 days and 7.8 ..mu..g F/m/sup 3/ for 14 days, applied before, during, or after flowering, had no apparent effects on fruiting of any of four varieties of beans. Fruiting was not affected in four bean varieties continuously fumigated at 2.2 ..mu..g F/m/sup 3/. Bean plants exposed continuously to HF at concentrations averaging 5.4, 6.6, and 13.9 ..mu.. F/m/sup 3/ produced fewer fruit and/or fewer seeds per fruit than comparable control plants. Only Tendergreen beans were tested at 5.4 ..mu..g F/m/sup 3/. Tendergreen and Pencil Pod Wax varieties showed effects on fruiting at 6.6 ..mu..g F/m/sup 3/, but Red Kidney and Tendercrop varieties did not. Fruiting was affected in both bean varieties tested at 13.9 ..mu..g F/m/sup 3/ (Red Kidney and Tendergreen). The severity of the HF treatments required to produce a response indicates that effects of HF on bean fruiting are of little practical significance. 7 references, 3 tables.
