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.
纳米粒子在提高粮食产量方面的农业恩赐给农业领域带来了新的革命。然而，它们对环境和生物多样性的协同影响的综合智慧仍然没有得到充分的探索。本研究旨在通过系统地探索六种不同类型的 C 点（源自天然生物质和塑料废物）对四种不同类型的种子（黑鹰嘴豆（Cicer arietinum）、大麦（Hordeum vulgare）、绿豆（Vigna radiata）和小麦（Triticum aestivum））在室温下的农业范式来解决这一担忧。C 点对选定种子的生长表现出剂量反应效应（250 至 5000mg/L），包括根长和胚芽鞘长的伸长。在合成 C 点存在的情况下，在大气条件下发育的幼苗对所有类型的种子都表现出极好的生理稳定性，干种子的浓度高达 3000mg/L。与水暴露相比，C 点的直接暴露导致生长增强，这被认为是本工作的最重要的新方面。由于其增强的表面积和非常小的尺寸，所开发的 C 点为种子提供了更多的营养物质并使其更容易渗透。在暴露 7 天后，发芽和活力指数也在 C 点存在下得到了提高。C 点对绿豆中的叶绿素含量随时间和浓度的变化而变化。所开发的 C 点具有出色的生物相容性行为，并有助于不同类型种子的完全生长，这表明它们在农业领域的增强利用。这是探索 C 点对广泛使用的粮食作物的影响的详细研究之一，这些 C 点具有无毒和生物相容性。本文所获得的信息将允许将 C 点用作种子自然萌发的有能力的纳米引发剂。
