Seed germination studies on Chickpeas, Barley, Mung beans and Wheat with natural biomass and plastic waste derived C-dots

Agronomical providence of nanoparticles in enhancing food productivity has brought new revolution in agricultural sector. However, the comprehensive ingenuity of their synergetic impact on environment and living flora and fauna is still poorly explored. The current study endeavours to tackle this apprehension by systematically exploring the agronomical paradigm of six different types of C-dots derived from natural biomass and plastic waste on the four different types of seeds viz. black chick peas (Cicer arietinum), barley (Hordeum vulgare), mung beans (Vigna radiata) and wheat (Triticum aestivum) at room temperature. C-dots have displayed a dose responsive effect (250 to 5000 mg/L) on the growth of chosen seeds, including the elongation of root length and coleoptile length. The development of seedlings under atmospheric conditions exhibited excellent physiological stability in presence of synthesized C-dots for all types of seeds with concentrations as high as 3000 mg/L for dry seed. The direct exposure of C-dots resulted in enhanced growth as compared to the water exposure and considered as the most important novel aspect of present work. The developed C-dots provide more nutrient content and easy penetration to the seeds due to their enhanced surface area and very small size. The germination and Vigor index have also been augmented in presence of C-dots after 7 days of exposure. C-dots have affected the chlorophyll content in mung beans as a function of time and concentration. The developed C-dots possess excellent biocompatible behaviour and help in the complete growth of the different types of seeds which suggest their enhanced utilization in the agronomical field. This is one of the detailed studies, which explore the impact of C-dots on widely used food crops with the non-toxic and biocompatible C-dots. The information achieved herein will allow the usage of C-dots as a capable nanopriming agent for the natural germination of seeds.
