Title

The effect of drought stress on physiological responses of maize plants originating from seeds of different ages

Ljiljana Prokić; Anja Lužaić; Bojana Živanović; et al. Selekcija i semenarstvo 2019. doi:10.5937/selsem1902009p

Other claims from this paper (6)

Intervention effect Drought decreased leaf area and transpiration rate in maize.
Intervention effect Drought treatments induced distinct chemical and hydraulic signals in maize.
Association Hydraulic signals had the same impact on stomatal reactions in D2012 and D2016 maize treatments.
Mechanism ABA chemical signaling promoted stomatal closure, with its effect dependent on leaf or root origin.
Association Leaf-originating ABA had a greater effect on D2012 stomatal closure.
Association Root-originating ABA and pH were more active in D2016 maize plants.
