irrigation intensity
2.Stomatal closure degree was reduced obviously by irrigation. Leaf stomatal resistance on the outer crowns of Coffea arabica,irrigated or non-irrigated,increased swiftly on sunny or cloudy days with a decrease in solar radiation intensity at below 300 μmolm-~2s-~1,and the daily average stomata1 resistance was 11.230 s/cm for the irrigated and 20.036 s/cm for the non-irrigated on sunny days.
