|a The effects of hypoxia at 0.003 mol O2 m-3 on growth and nitrogen uptake of wheat seedlings (Triticum aestivum L. ev. Gamenya) was compared between plants growing in nutrient solutions containing either NO3 - only, or NO3 - plus NH4 + . Hypoxia reduced the uptake of N by the plants, however both at 0.28-0.31 mol O2 m-3 (aerated solutions) and 0.003 mol O2 m-3 , rates of N uptake from solutions containing NO3 - plus NH4 + were 34% higher than from solutions containing NO3 - only. In aerated solutions, growth was faster when NO3 - plus NH4 + was supplied. By contrast, at 0.003 mol O2 m-3 both N treatments had the same low growth rate (expressed on a dry weight basis) despite considerably higher internal N concentrations in the plants supplied with NO3 - plus NH4 + . It is concluded that N nutrition did not limit growth at 0.003 mol O2 m-3 in either N treatment. Other possible causes of the growth reduction and differences in uptake characteristics between NO3 - and NH4 + are discussed
