2、土中三种土壤酶活性的影响。结果表明,在整个生育期内,两种类型土壤的土壤脲酶活性均呈现“升高一降低一升高”趋势,蔗糖酶均呈现“升高一降低”趋势,而脱氢酶在盐碱土壤中呈现“升高一降低”趋势,在普通耕土中始终是降低的;盐碱土壤的脲酶和脱氢酶高于普通耕土,蔗糖酶活性低于普通耕土;与非转基因受体对照相比,转基因玉米株系种植在盐碱土中促进土壤脲酶活性,抑制土壤蔗糖酶活性,拔节期时达到差异显著(P3、抑制作用,分别在拔节期和吐丝期时达到差异显著(P4、ewithgeneBADH(ZeamaysL.)onsoilenzymesactivity[J].JournalofNo~heastAgriculturalUniversity,2014,45(4):25-29.(inChinesewithEnglishabstract)Effectofgeneticallymodifiedsalt-tolerantmaizewithgeneBADH(ZeamaysL.)onsoilenzymesactivity/DrHong,ZHOUChengsheng,ZENGXing,WANGShumin,WANGYuhe,WAN5、GZhenhua(Sch0ol0fAgriculture,NortheastAgriculturalUniversity,Harbin150030,China)Abstract:Theefectsofgeneticallymodifiedsalt-tolerantmaizewiththegeneBADHonsoilurease,sucraseanddehydrogenaseactivityatdifferentgrowthstagesinsaline-alkalisoilandcommonsoilunderthefiledcondition.Theres6、ultsshowedthatdudngthewholegrowthpedod,ureaseactivityincreasedatfirstandthendecreasedandincreasedfinallyintwotypesofsoil.Sucraseactivityincreasedatfirstandthendecreased,dehydrogenaseactivityincreasedatfirstandthendecreasedinsaline—alkalisoil,andalwaysdecreasedincommonsoil.Compare7、dtocommonsoil,theureaseanddehydrogenaseactivityofsaline-alkalisoilwerehigherandsucroseactivitywaslower.Theplantingoftransgenicmaizeinsaline-alkalisoilincreased(26_77%)ureaseanddehydrogenaseactivityanddecreased(53.73%)sucroseactivitycomparedwithnon-transgenicmaize,andthedifference8、sreachedthesignificantlevel(P<0.05)andth
