| Abstract | ||||
| THE MITIGATING effects of salicylic acid (SA) and cytokinin (CK) against glyphosate stress on young maize plants were investigated. The application of glyphosate has harm effects on maize plants, i.e. plants became shorter, chlorosis, leaves turned to yellow more or less dry in some parts then died. The morphological changes associated with decrease in the chlorophyll content; meanwhile the levels of protein, proline and the activity of ascorbate peroxidase (APX), catalase (CAT), peroxidase (POD) and superoxide dismutase (SOD) were increased. Available data suggest that the protective effect of SA and CK was accompanied with increase in chlorophyll content and reduction in proline and the activity of APX, CAT, POD and SOD in comparison with glyphosate treatment. The combination between SA and CK not alleviate the harm effects of glyphosate on maize. The present results gave an insight about the use of SA and CK alone in alleviated in some extent the detrimental effects due to the glyphosate action. | ||||
