不同变黄温度对烘烤过程中烟叶变黄及能量代谢的影响牛浩1赵亚峰2刘剑君3尹光庭2赵浩宾3魏壮状2王鹏飞3段卫东2*（1河南农业大学烟草学院，河南郑州450002；2河南中烟工业有限责任公司技术中心，河南郑州450016；3中国烟草总公司河南省公司，河南郑州450018）摘要为明确变黄温度对烤烟烘烤过程中变黄速度及能量代谢活动的影响，以烤烟中部叶为试验材料，开展烘烤试验，通过对烟叶变黄程度、丙二醛（MDA）含量、浸出液电导率、能量代谢相关物质（ATP、ADP、AMP）含量、能荷进行测定，分析了不同变黄温度下烟叶的变黄过程。结果表明，与38℃处理相比，40℃处理烟叶烘烤过程中变黄更快，MDA含量和浸出液电导率更高，ATP峰值出现较早且ATP含量和能荷水平相对较高。较高的变黄温度可能提高了烟叶能量代谢强度，进而加快了烟叶变黄过程。关键词烤烟；变黄温度；烘烤；MDA；能量代谢中图分类号S572文献标识码A文章编号1007-5739（2023）07-0189-05DOI：10.3969/j.issn.1007-5739.2023.07.052开放科学（资源服务）标识码（OSID）：EffectsofDifferentYellowingTemperaturesonYellowingandEnergyMetabolismofTobaccoLeavesDuringCuringProcessNIUHao1ZHAOYafeng2LIUJianjun3YIGuangting2ZHAOHaobin3WEIZhuangzhuang2WANGPengfei3DUANWeidong2*(1CollegeofTobacco,HenanAgriculturalUniversity,ZhengzhouHenan450002;2TechnologyCenterofHenanChinaTobaccoIndustryCo.,Ltd.,ZhengzhouHenan450016;3ChinaTobaccoCorporationHenanBranch,ZhengzhouHenan450018)AbstractToclarifytheeffectofyellowingtemperatureontheyellowingrateandenergymetabolismduringthecuringprocessofflue-curedtobacco,themiddleleavesofflue-curedtobaccowereusedasmaterials,andthecuringtestwascarriedout.Throughthedeterminationofyellowingdegree,malondialdehyde(MDA)content,conductivityoflea-chingsolution,relatedsubstancescontentofenergymetabolism,andenergycharge,theyellowingprocessoftobaccoleavesatdifferentyellowingtemperatureswereanalyzed.Theresultsshowedthat,comparedwiththetreatmentat38℃,thetobaccoleavestreatedat40℃turnedyellowfasterduringthecuringprocess,andtheconductivityofMDAcontentandleachingsolutionwerehigher;theATPpeakappearedearlier,andtheATPcontentandenergychargelevelwererelativelyhigher.Thehigheryellowingtemperaturemay...
