What is a simple and short method to calculate the water use efficiency of different maize Inbred Lines?
The relative water content of a piece of leaf,
15 mm long, was estimated according to Weatherley
(1950). The amount of transpired water (T) was
calculated by subtracting the evaporated water (Es),
determined for the control tubes, from the total water
loss per column. The WUE was calculated as WUE=
TE/(1+Es/T) where TE is the transpiration efficiency
(StDW/T) (Richards 1991).
The term efficiency mean a slope of carbon gain versus transpired water, but for practice is often used the water quotient thatis the yield relative to water supply. If you have data on parcels you may rank the ones that are less affected yunder partial stress relative to pan evaporation ratios
