Abstract :

Introduction: Zinc oxide nanoparticles are very important due to their utilization in gas sensors, biosensors, cosmetics, drug–delivery systems, and many more. Zinc oxide nanoparticles (ZnO NPs) exhibit remarkable optical, physical, and antimicrobial properties and therefore have great potential to upgrade agriculture. The purpose of these NPs leads to their discharge and growth up in the environment affecting both plants and animals system, which highlight to study the toxicity of both bulk and NPs. Aim:– The present study is aimed at investigating the effects of zinc oxide nanoparticles (nano–ZnO) and zinc oxide bulk particles on chickpeas. Method:–Four parameters are examined in this study: seed germination percentage, root length, Different concentration (250, 500, 1000 and 2000 mg/L) of ZnO Nps and ZnO bulk particles were prepared in distilled water and used for the treatment in chickpeas. Result:–The results showed that with increase in the concentration of zinc oxide nanoparticles the germination percentage decreases. This study showed that the use of the zinc oxide nanoparticles and bulk zinc oxide can reduce of the seed germination under controlled condition in comparison with control seed. The present study showed that with increasing the concentration from 250mg/L>500mg/L>1000mg/L>2000mg/L the root length decreases Conclusion:–It was concluded that the zinc oxide nanoparticles affect the physiological expression of plant. Nano–ZnO is found to stunt roots length
