Response of maize (Zea mays L. saccharata Sturt) to different concentration treatments of deltamethrin
چکیده انگلیسی


• We investigate the effect of the deltamethrin pesticide on the biological properties of maize.
• We determined the germination, morphological, anatomical and physiological responses of maize seedlings.
• We observed that all seedling growth characters were decreased with increasingly deltamethrin doses.
• The results showed that chlorophyll and caretonoids decreased with deltamethrin treatments.
• Anthocyanin and proline content increased in parallel with deltamethrin concentration.

The aim of this study was to investigate the effect of the deltamethrin pesticide on the biological properties of maize (Zea mays L. saccharata Sturt). Maize seeds were exposed to environmentally relevant dosages (0.01, 0.05, 0.1 and 0.5 ppm) of deltamethrin. On the 7th day of germination, morphological, anatomical and physiological responses were determined. All seedling growth characters were decreased with increasing deltamethrin levels. The most negative effect on the radicle length of maize was observed by the highest deltamethrin concentration with a 61% decrease (P < 0.05). Both stomatal density and stomatal dimension reduction were caused by increasing concentrations of deltamethrin. Moreover, the pigments like chlorophyll a, chlorophyll b, total chlorophyll and caretonoids decreased with the increase in deltamethrin concentration. Conversely, anthocyanin and proline content increased in parallel with deltamethrin concentration. As a result, all morphological traits and pigments except for proline and anthocyanin were significantly reduced with an increase in pesticide concentration, compared to control (P < 0.05).
