Abstract
In this study, investigated the possible mediatory role of salicylic acid (SA) in protecting Zea mays L. “Martha F1” seedlings from glyphosate toxicity. 0.5 mM SA was treated as preemergence and 17-145 mM glyphosate herbicide was treated postemergence to same groups. The effects upon Peroxidase (POD), Ascorbate Peroxidase (APX), Superoxide Dismutase (SOD), Catalase (CAT) reduced glutathione (GSH), Glutathione Reductase (GR), Glutathione S Transferase (GST), lipid peroxidation, total chlorophyll and total soluble carbohydrate content of this herbicide were investigated on the 1st, 5th and 10th days following the treatment.
Highlights
IntroductionWhile in western countries maize production is highly mechanized, in many other -mainly developing countries - the crop is still grown by smallholders and medium-scale farmers, using traditional and low-input cultivation techniques
Zea mays L. is the most important cereal crop in the World after wheat and rice
POD activity was highest on the 1st day in 66 mM glyphosate applied group, on the 5th day and 10th day in 111 mM glyphosate applied group
Summary
While in western countries maize production is highly mechanized, in many other -mainly developing countries - the crop is still grown by smallholders and medium-scale farmers, using traditional and low-input cultivation techniques. Yields under those circumstances are much lower. Maize is an important staple food in developing countries, and a basic ingredient for local drinks and food products. It is and outstanding feed for livestock, high in energy, low in fiber and digestible. As a source of starch, it is major ingredient in industrialized food products [1]
