中国农业科学2007,40(2):345-351 ScientiaAgriculturaSinica 套袋对越冬番茄果实特性及品质的影响 王磊1,2,徐坤1,高方胜3,徐宁1 (1山东农业大学园艺科学与工程学院,泰安271018;2德州农业科学研究院,德州253015;3德州学院农学系,德州253015) 摘要:【目的】明确套袋对番茄果实生长发育、果实特性、果实品质及农药残留的影响。【方法】以番茄品种 JYK为试材,研究了不同材质果袋处理的生物学效应。【结果】套袋显著降低了番茄果实的硬度、可溶性固形物含 量和糖酸比,减少了果实Vc、可溶性糖等物质含量,降低了果实的农药残留,加速了果实叶绿素的降解,但增加 了果实含水量,促进了果实类胡萝卜素和番茄红素的合成。番茄果实成熟时,硫酸纸袋、无纺布袋及塑料袋处理 的果实番茄红素含量分别比不套袋提高了8.2%、60.9%和41.7%,且不套袋和套袋之间番茄红素含量达到了显著差 异。此外,套袋还可增加果实的单果重,其中以硫酸纸袋效果最佳,塑料袋和无纺布袋次之,三者分别比不套袋 增加了15.34%、13.22%和9.02%,套袋与不套袋之间差异达显著水平。【结论】套袋影响番茄果实的营养品质,但 改善了番茄果实外观商品性状。 关键词:番茄;套袋;果实特性;色素;品质 EffectsofBaggingonFruitCharacteristicsandQualityinTomato FruitsThroughWinter WANGLei1,2,XUNKun1,GAOFang-sheng3,XUNing1 (1CollegeofHorticulturescienceandengineeringofShandongAgriculturalUniversity,Taian271018;2AcademyofAgriculture ScienceofDezhouCity,Dezhou253015;3AgronomyDepartmentofDezhouUniversity,Dezhou253015) Abstract:【Objective】Thestudyresearchedeffectsofbaggingonthedevelopment,fruitcharacteristics,qualityandpesticide residualintomato.【Method】Tomato“JYK”(LycopersiconesculetumMill)wasusedtodeterminethebiologicaleffectsofdifferent texturebags.【Result】Baggingdecreasedfruitrigidity,solublesolidandtheratioofsugarandacid,significantly,otherwisebagging alsoreducedthecontentofpesticideresidual,flavorqualitysuchasvitamineC,solublesugaretc..Meanwhile,thechlorophyll decomposingwasaccelerated,watercontentwasincreasedandthebiosynthesisofcarotenoidandLyconepewereimprovedunder bagging.Inthefruitripeningstage,contentsofLyconepeofparchmentbag,no-spinningclothbagandplasticbagseparatelywere higherthannon-baggingby8.2%,60.9%and41.7%,andbetweennon-baggingandbagging,itwassignificantlydifferent.Moreover, thetreatmentswithbaggingincreasedthesinglefruitweightby15.34%,13.22%and9.02%respectivelycomparedtonon-bagging, andthatofparchmentbagwashighest,higherthanplasticbagandno-spinningclothbag.Singlefruitweightbetweenbaggingand non-baggingwassignificantlydifferent.【Conclusion】Therefore,thequalityoftomatofruitwasinfluencedunderbaggingwh
