Transpiration Patterns of Wheat, Barley and Oat Seedlings Under Varying Conditions of Soil Moisture1

Synopsis

Synopsis

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.
