摘　　要：以‘阳光玫瑰’葡萄为试验材料,研究赤霉酸(GA_(3))、氯吡脲(CPPU)、噻苯隆(TDZ)不同施药方式、处理时期、处理浓度以及搭配组合对果实品质的影响,以期筛选出适合‘阳光玫瑰’无核化栽培使用的组合配方。结果表明:在花开24 h内使用2 mg·L^(-1)TDZ+1 mg·L^(-1)CPPU+15 mg·L^(-1)GA_(3)浸蘸花穗,并且在果实膨大初期使用4 mg·L^(-1)TDZ+25 mg·L^(-1)GA_(3)浸蘸果穗处理效果最好,单穗质量、单粒质量分别为779.24 g、9.84 g,与清水对照相比分别增加了35.14%、22.24%;果粒长度为27.69 cm、宽度为24.75 cm、无核率为96%,与对照相比分别增加了8.97%、16.53%、118.18%;总酸含量为3.98 g·kg^(-1),与对照相比减少了7.44%,维生素C含量为7.98μg·g^(-1),比对照增加了48.60%,可溶性糖含量为16.28%,比对照增加了21.95%。该处理无核率高,果粒较大,口感较好,能显著改善果实品质,为‘阳光玫瑰’葡萄最适宜的植物生长调节剂组合。The‘Shine Muscat'grapes were used as the experimental material.Combined treatments of gibberellic acid(GA_(3)),forchlorfenuron(CPPU),tiabenon(TDZ)were used to study their effects on fruit quality under different application methods,treatment periods,concentrations and combinations.The results from this were then used to screen for the best combination of growth regulators,and provide scientific basis for its cultivation of denuclearization.Results showed that:dipping 2 mg·L^(-1) TDZ+1 mg·L^(-1) CPPU+15 mg·L^(-1) GA_(3) into flower spikes within 24 h of blooming,dipping 4 mg·L^(-1) TDZ+25 mg·L^(-1) GA_(3) in the early stage of fruit expansion had the best effect.The cluster mass and single fruit weight were 779.24 g and 9.84 g,respectively,which were increased by 35.14%and 22.24%compared with the water control group.The longth of the fruit was 27.69 cm,the width of fruit grain was 24.75 cm,and the seedless rate was 96%,which increased by 8.97%、16.53%and 118.18%compared with the control.The total acid content was 3.98 g·kg^(-1),decreased by 7.44%compared with the control group,vitamin C content was 7.98μg·g^(-1),increased by 48.60%compared with the control group,soluble sugar content was 16.28%,increased by 21.95%compared with the control group.This treatment had larger fruit size and better taste,and could significantly improve the fruit quality of‘Shine Muscat'.It is the most suitable combination of planting and conditioning for‘Shine Muscat'grape.
