Barley plants had the lowest transpiration rate and oats the highest under both greenhouse and growth chamber conditions. For all plants there was a linear relationship between soil moisture content and transpiration loss. Plants subjected to a single period of moisture stress showed a marked reduction in transpiration from the prestress rate. Water use efficiency was the same for the 3 genera in the growth chamber, but in the greenhouse barley had a much greater efficiency than wheat or oats.
