Abstract
Exposures of wheat Triticum aestivum L. cv. ‘Olaf’ to gaseous hydrogen fluoride (HF) in the field reduced yield but did not cause foliar injury. The effects on yield were modified by the stage of development at the time of exposure. Four-day exposures to 0·9 μg of fluoride per cubic metre at the boot stage of development resulted in reduced yield due to smaller spikes. However, exposure to 2·9 μg of fluoride per cubic metre did not affect yield because the smaller size of spikes was offset by an increase in the number of spikes produced per plant. At anthesis, HF-induced yield reductions were the result of both smaller and fewer spikes per plant. There was no significant difference between the concentration of fluoride in the spikes of treated and control plants, indicating that fluoride accumulated in vegetative tissues during the exposures was not translocated to the developing grains.
