I杂环腺类细胞分裂素诱导荔枝单性结实的试验研究李再峰，欧阳乐军，李莉梅(湛江师范学院广东高校边缘热带特色榊物工程技术开发中心，湛江524048)摘要：[目的】试验探索无单性结实能力和自然单性结实的荔枝品种在杂环號类细胞分裂素诱导下产生单性结实果和异常果的可能性，【方法】应用研制的杂环腺类细胞分裂素2mg/L,对廉江良堀镇果园无单性结实的桂味、广良红、妃子笑和单性结实的海南无核荔枝在花期喷施果穗，10-15d再喷施1次，果实成熟取单性结实果、异常果和正常果样品测定并进行分析。【结果】花期应川杂环魔类细胞分裂索，使无单性结实能力的桂味、广良红、妃子笑和单性结实的海南无核品种荔枝诱导产生无核的单性结实果和异常果，但单性结实和片常果的果实比正常果实小，桂味、广良红、妃子笑单性结实果和海南无核界常果比正常果的平均单果重分别降低112.2%、29.5%、93.1%和79.3%；桂味、广良红荔枝单性结实果的可溶性固形物比正常果高，而妃子笑单性结实果和海南无核果的可溶性固形物比正常果低。【结论】试验说明杂坏咏类细胞分裂索可以激发某些无单性结实能力的荔枝品种的单性结实潜能，无单性结实能力的荔枝可通过化学诱导产生单性结实果。关键词：荔枝；杂环腺类细胞分裂素；单性结实；无核果：S667.1TheexperimentalstudyofLitchi(LitchichinensisSonn)parthenocarpyinducedbyheterocyclicureascytokininLIZai-feng,OUYANGLe-jun,LILi-meiUniversityEngineeringTechnologyDevelopmentCenterofFringeTropicalCharacteristicPlantinGuangdongZhan激angNormalUniversity,Zhan激ang,524048Abstract:EObjective1Theobjectiveofthestudyistoexplorethepossibilitiesoftheparthenocarpicseedlessfruitsofthenon-parthenocarpicabilitylitchiesandtheabnormalfruitsoftheparthenocarpicabilitylitchiwereproducedbyapplyingheterocyclicureacytokinin-induction>[Method]2mg/LoftheheterocyclicureacytokininpreparationwereappliedtosprayingdirectlyontheearsinfloweringofnonparthenocarpicGuiwei,Guanglianghong,FeizixiaoandofparthenocarpicHainanSeedlessLitchiesatLian激angLiangdongtown'sorchard,10-15dthensprayed1,theparthenocarpicfruits,abnormalfruitandthenormalfruitsweresampledanddeterminedanalysiswhentheygetripe.【Result]Theresultsshowedthattheparthenocarpicseedlessfruitsofthenon-parthenocarpicabilityGuiwei,GuanglianghongandFeizixiaolitchiesandtheabnormalfruitofparthenocarpicHainanSeedlesslitchiwereinducedbyapplyingheterocyclicureacytokinintoLitchiesinflowering,butparthenocaipicfruitsweresmallerthannormalfruit,theaveragefruitweightsoftheparthenocarpicfruitofGuiwci,Guanglianghong,FeizixiaolitchiesandoftheabnormalfruitofHainanSeedlesslitchiweredecreasedby112.2%,1、基金项hl：岭南佳果龙眼.荔枝的烏效抗裂果剂的研制和应用推广(国家星火项H20UGA780057)；广东高校边缘热带特色杭物工程技术开发中心项目(GCZX-B1002).2、作者：李再峰(1952.2),男,宁夏银川人,教授,硕士，长期从事有机化学、农业化学方面教学和科研工作。E-mail：lizaifcng_zjnu@163,lc】:0759・318258729.5%,93.1%and79.3%relativetoofthenormalfruitrespectively;thesolublesolidscontentsoftheparthenocarpicseedlessfruitsofGuiweiandGuanglianghonglitchieswerehigherthanoffruitofnormalGuiweiandGuanglianghong,andoftheparthenocarpicfruitofFeizixiaoandoftheabnormalfruitofHainanSeedlesslitchieswerelowerthanofnormalfruit・【Conclusion]Thestudiessuggestedthattheparthenocarpicpotential,ofsomenon-parthenocarpicabilityvarietiesoflitchiesmaywerestimulatedbyheterocyclicureacytokinin,andtheparthenocarpicfruitsofthenon-parthcnocarpicabilitylitchiesmaywereproducedbychcmical-inductionprocess・Keywords:Litchi；Heterocyclicureacytokinin;Parthenocarpic;Seedlessfruit园艺作物单性结实(parthenocarpy)的性能已早为...
