Abstract：Carbondots（CDs），asanovel class ofnanomaterials，have garnered increasing atention intheagriculturalfieldduetotheiradvantagessuchaslowcost，easeofsynthesis，lowtoxicity，biodegradability，highquantumyield， small ize，and excellentbiocompatibility.Inthis paper，wereviewedtheefectsofCDsonthegrowthanddevelopmentof cropsand elaborated on the mechanisms through aspects such as seed germination，root growth and development，mineral elementbsorption，photosyntheticeactions，carbonassimilation，ntioxidantcapacity，ndstress resistance，withtheim of providing theoreticalreferences forthesafeandsustainableimprovementofcropyield.Finally，wediscussedthechallnges faced by the potential applications of CDs in agricultural systems.
