Abstract

Soybean (Glycine max L.), maize (Zea mays L.), peanut (Arachis hypogaea L.) and navy bean (Phaseolus vulgaris L.) were exposed to SO2 (≈280, ≈140 or < 13 μg/m3) and HF (≈0.26 or <0.03 μg/m3) separately or together, for 8 hr per day in a factorial experiment in open top chambers from the seedling stage to harvest. The gases had little effect on soybeans. SO2 or HF alone caused an accelerated or more even kernel ripening in maize, and their combination increased the dry weight of maize cobs by over 40%. SO2 alone reduced the number of mature pods and kernels in peanut, but the weight of kernels produced was unchanged. In contrast, HF alone reduced yield (expressed as weight of kernels per plant.) Mixtures of HF and SO2 induced less than additive responses. Exposure of navy beans to SO2 or HF alone increased the number of pods and beans per plant. However, average bean weight was reduced by exposure to HF or 290 μg/m3 of SO2 resulting in no net change in yield. Yield was, however, increased by exposure to 141 μg/m3. Mixtures of SO2 and HF induced less than additive responses in navy bean. Leaf sulfur concentrations were increased by exposure to ≈ 280 μg SO2/m3 but unaffected by ≈ 140 μg/m3.
