The revolutionary growth in the usage of carbon quantum dots (CQDs) in different areas have ultimately directed their discharge in the environment and further augmented the exposure of agricultural crops to these released particles. Therefore, the aim of current study is to evaluate the uptake, translocation and phytotoxicity of blue emissive CQDs on Allium sativum plant. The genotoxicity and cytotoxicity assessment of CQDs towards Allium sativum roots was estimated as function of three different concentrations. Considering the role of CQDs in promoting seed germination at 50 ppm concentration, a greenhouse experiment was performed to evaluate their effect on plant growth. Systematic investigations have shown the translocation of CQDs and their physiological response in terms of increased shoot length wherein P-CQDs exhibited more accumulation into Allium sativum parts. Our investigations unfold the opportunity to utilize Aegle marmelos fruit derived CQDs as a growth regulator in variety of other food plants.
碳量子点（CQDs）在不同领域的使用呈革命性增长，最终导致其在环境中的排放，并进一步增加了农业作物对这些释放颗粒的暴露。因此，目前的研究旨在评估蓝色发光 CQDs 对大蒜植物的吸收、迁移和植物毒性。根据三种不同浓度，评估了 CQDs 对大蒜根的遗传毒性和细胞毒性。考虑到 CQDs 在 50ppm 浓度下促进种子发芽的作用，进行了温室实验来评估它们对植物生长的影响。系统研究表明，CQDs 的迁移及其在增加茎长方面的生理反应，其中 P-CQDs 更多地积累到大蒜的各个部位。我们的研究揭示了利用酸橙衍生的 CQDs 作为各种其他食用植物生长调节剂的机会。
