The effect of H2S on the growth of curly kale (B. oleracea Bornick) was investigated in the Netherlands. Kale was insensitive to atmospheric H2S: growth was only adversely affected at >=0.4 micro l/litre. Shoots formed a sink for H2S. The uptake rate showed saturation kinetics with respect to atmospheric concentration. H2S uptake rate was high in comparison with other species, which may reflect the high S need of kale. Net uptake of sulfate by roots of hydroponically grown plants was substantially reduced after 1 week of exposure to 0.25 micro l H2S/litre. Plants were S deficient after 2 weeks of S deprivation.
