Salinity stress and the senescence process in wheat (Triticum aestivum L.)

Salinity stress and the senescence process in wheat (Triticum aestivum L.)

Salinity/Water stress commonly cause leaf yellowing due to changes in chlorophyll, reduction in endogenous cytokinins as well as an enhancement in abscisic acid (AbA) contents. Since cytokinin (CK) and abscisic acid (AbA) levels are known to differentially influence the senescence process, their eff...

Zusammenfassung:Salinity/Water stress commonly cause leaf yellowing due to changes in chlorophyll, reduction in endogenous cytokinins as well as an enhancement in abscisic acid (AbA) contents. Since cytokinin (CK) and abscisic acid (AbA) levels are known to differentially influence the senescence process, their effect(s) on chlorophyll contents of salinity stressed wheat (Triticum aestvium L.) seedlings showed that chlorophyll degradation was reduced by CK, benzylamino purine, BAP, but not by other treatments.
