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.
