“…4a). These responses were in accord with the results of Siopongco et al (2008), which implicated leaf ABA as a chemical signal from roots to reduce stomatal conductance under mild drought. Upon severing roots subjected to drought, reductions in both Ψ L and g s were observed for one day, which were probably due to wounding, but both parameters resurged strongly and thereafter, continued to increase progressively with time.…”

“…The previous study in this series, (Siopongco et al, 2008), demonstrated the existence of root signals in rainfed lowland rice. The decrease in g s and transpiration rate (Tr) before any decrease in leaf water potential (Ψ L ), which was associated with increased soil moisture tension (SMT) and a rise in leaf ABA, was consistent with the influence of a chemical signal under mild drought.…”
