Abstract：To clarify the effects offorchlorfenuron（CPPU）onthe growth and qualityof different cucumber types and provideatheoreticalbasis for preciseregulation，this studyusedthe SouthChina-type cucumber Lubaozhu No.6，the European-type cucumber Licui No.2，and the North China-type cucumber Bojie 616 as test materials.On the day of femalefloweropening，a10mg·LCPPUsolutionwasappliedbyspraying，andthefruit-settingrate，fruit growthdynamics， single fruit mass，and quality indicators suchassoluble protein，soluble sugar，soluble solids，vitamin C，andamino acid content were systematicallmeasured.Theresultsshowed thatcompared withthecontrol，CPPU treatmentsignificantly increased the growthrate，single fruit massand fruit-settingrateofallcultivars，and increased the fruit-settingrateof Lubaozhu No.6 and Liicui No.2 to 100% . It also significantly enhanced the soluble sugar，soluble solid，and protein content in allthree cucumber cultivars.Specifically，after treatment，Licui No.2 exhibited increases of 3.7% ， 8.9% ，and 8.4% compared to the control，while Lüibaozhu No.6 showed increases of 11.9% ， 13.7% ，and 11.9% ，respectively. The regulation offreeaminoacidsby CPPU exhibited significantcultivar-dependent differences，increasing the contentof various freeaminoacidsinLubaozhuNo.6andLucuiNo.2，andreducing theaminoacidcontentofofkeyflavors such as glutamate and proline in Bojie 616. In conclusion， 10mg⋅L-1 CPPU effectively improves cucumber yield and most nutritionalflavorindicators，butitsregulationofaminoacidisstronglyvariety-dependent.Therefore，theapplicationof CPPU in production must fully consider cultivar characteristics to achieve genuine high quality and yield.
