Abstract：Toimprovethegermnationqualityoftobaccoseeds，cultivatestrongsedings，anddevelopanoveltobaccosdviality synergist，the majorflue-cured tobacocultivator Zhongyan10Oseeds wereusedasexperimentalmaterials inthisstudy.Water was usedas thecontrol，andteefectsofibberell，Haiinong，anddierentconcetrationsofstraw-derivedsokewatered germinationandseedling growth werecompared.Treatment withsmoke waterata1：80o dilutionsignificantly increased germiation potential， germination rate，and germination index by 4.30% 3.93% ，and 5.62% respectively， compared to the control. Notably， the germinationindexunderthis treatment was significantly beterthanthatunder Haiyinong treatment.The dynamicchanges in antioxidantenzymeactivitydurigseedgerminationinalltreatmentsweregenerallyconsistentwiththoseofthecontrol.Totdry mass，shoot fresh mass， and dry mass of tobacco seedlings treated with 1：800 smoke water were significantly greater than those treatedwith gibberellin，withthe increases of 35.32% 53.19% ，and 43.92% ，respectively.However， chlorophyll content under smoke watertreatment wassignificantlylowerthanthatundergibberellntreatment.Underdual treatmentofseed initiationandseedling spraying with 1：800 smoke water， the membership function values of key indicators including plant height，root length， shoot and rootdryandfreshmassandchlorophyllcontentwerehigher thanthoseobservedwithHaiyinongandgiberelintreatments.These resultsindicatethatsmoke wateratthisconcentrationmost efectivelypromotes tobaccoseed germinationandseedlinggrowth， demonstratingitspromisingapicationpotential.Withitshigheficiency，safety，lowcost，andevironmentalfrendlise smoke water canserve as a new gree plant growth promoter for tobacco sed priming andsedlingcultivation.This study also provides areference for the broader application of smoke water in seed priming and seedling development of other crops.
