Abstract:Highlights
Hourly sap flow measured in co-located and identically managed maize, sorghum, and soybean closed canopies.
PAR, VPD, and ETr were strongly correlated to transpiration (T) normalized by LAI.
Negative response of T to high VPD (3-4 kPa) was observed for maize and sorghum.
Counterclockwise hysteresis observed for diurnal T-VPD and T-PAR.
MLR models were developed to estim… Show more
