Abstract

With the development of nanotechnology, metal oxide nanoparticles have been applied in many industries, increasing their potential exposure level in the environment, yet their environmental safety remains poorly evaluated. Present work demonstrated the effects of ZnO and TiO2 nanoparticles on the germination, morphoanatomical attributes and biochemistry of Cicer arietinum. The nanoparticles are used in three doses, i.e., 100, 500 and 1000 ppm along with control and each dose has three replicates. Results demonstrated that ZnO nanoparticles did not aid in the germination of seed, whereas TiO2 nanoparticles showed positive impact on germination at 48-h observation. But at 72-h observation both the nanoparticle-treated and control seeds showed 100% germination. Morphological parameters revealed that ZnO nanoparticles have drastic negative impact on both root and shoot length, root and shoot fresh and dry biomass. On the other hand, the status of chlorophyll is almost opposite, i.e., ZnO nanoparticle-treated plants showed higher pigment content than TiO2 nanoparticle-treated plants. From the statistical point of view, it is revealed that ZnO nanoparticle-treated plant showed significantly different results than that of TiO2 nanoparticle-treated plants in Chl ‘a’ (p
