2、对两因素对我国农作物的不利影响提供基础理论依据。【方法】以八月黄大豆品种为试材,采用大田开顶式气室(OTC)进行太阳辐射减弱和O,浓度增加单因子及其复合条件下对大豆荧光特性与产量的影响试验。试验设4个处理,分别为:CK(不通0,、不作辐射减弱处理)、Tl(不通0,,辐射减弱20%)、T2(100n饥0,处理)、T3(100n饥0,和辐射减弱20%复合处理)。【结果】相对于CK,T1、T2、T3处理条件下大豆的Pm、I。、Yield、qP显著下降;L(一)、NPQ、Y(NPQ)、(1.qP)/NPQ显著增大;T1、T2、T3
3、处理对快速光响应曲线的初始斜率(0【)没有明显影响;T1处理对F卯。值无明显影响,T2、T3处理的FF。值显著下降;T1处理的Y(NO)值显著增大,T2处理的Y(NO)值显著减小,而T3处理没有显著改变Y(NO)值。相对于CK,T1、T2、T3处理条件下大豆的固氮能力、生物量和产量均显著降低,且呈TI4、豆;叶绿素荧光;产量;太阳辐射;臭氧中图分类号:$565.1l文献标志码:A文章编号:2095—1191(2013)08—1295—08Combinationeffectsofreducedradiationandenhanced03stressonchlorophyllfluorescencecharacteristicsandyieldofsoybeanZHENGYou—fei8,GUKang—le8,WURong-jun6,XUJing-xin8,SHIMing—huaa,HUHui-fan96(8Collegeof5、AtmosphericPhysics,NanjingUniversityofInformationScience&Technology,Nanjing210044,China;bCollegeofEnvironmentalScienceandEngineering.NanjingUniversityofInformationScience&Technology,Nanjing210044,China)Abstract:【Objective】Effectsofenhancedozonestressandreducedsola6、rirradianceonthechlorophyllfluorescenceresponsesofsoybeanwerestudiedtoprovidetheoreticalreferencesforreducingthenegativeeffectsofthetwoelementsoncropsinChina.【Method】nefieldopentopchamber(OTC)wasappliedtoreducesolarirradianceandenhanceozonestress.Augustyellowsoybe7、anvarietywasusedtoevaluatetheeffectsofenhancedozonestressandreducedsolarirradianceonyieldandchlorophyllfluorescenceresponsesofsoybean.Fourtreatmentswereperformedinfield(CK,OTC;T1,80%naturallight;T2,100n饥103;T3,100nI几03and80%naturallight).【Resuh]P。,Ik,yieldandqPofT8、l,rI'2,T3treatmentsdecreasedsignificantlycomparedtoCK.L(PFD),NPQ,Y(NPQ),(1-qP)/NPQofT1,r112,T3treatmentsincreasedsignifi—candycomparedtoCK.Thedofrapidli
