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 enhancem ent in abscisic acid (AbA) contents. Since cytokinin (CK) and abscisic acid (AbA) levels are known to differentially influence the senescenc e process, their effect(s) on chlorophyll contents of salinity stresse d wheat (Triticum aestvium L.) seedlings showed that chlorophyll degra dation was reduced by CK, benzylamino purine, BAP, but not by other tr eatments.
