【摘要】 本次研究以‘阳光玫瑰’葡萄为试验材料,研究GA3、CPPU、SM以及TDZ之间在不同处理时期、不同浓度及不同搭配方式下对‘阳光玫瑰’葡萄花穗生长、无核率以及果实品质的影响,期望找到进一步提高‘阳光玫瑰’葡萄花果管理效率及果实品质的方法,为生产上提供一些理论支持。研究结果如下:1.在花前使用不同浓度CPPU处理‘阳光玫瑰’葡萄研究中,结果表明:花前CPPU处理对于提高‘阳光玫瑰’葡萄果实纵、横径及单果质量,花穗拉长效果显著,而且随着CPPU处理浓度的升高而升高,以使用CPPU3 mg/L处理效果最佳。2.在花前使用不同浓度SM处理‘阳光玫瑰’葡萄研究中,结果表明:各处理均能有效提高‘阳光玫瑰’葡萄无核率,最高可达96.1%,提高了果实的可溶性固形物含量,降低可滴定酸含量,提高固酸比效果显著。同时,SM会降低果实的单果质量,并不是使用浓度越高越好。综合以上情况考虑,花前以SM 200 mg/L处理‘阳光玫瑰’葡萄综合品质较好。3.在搭配使用GA3、TDZ及CPPU处理‘阳光玫瑰’葡萄研究中,结果表明:在盛花期使用GA3 20mg/L+TDZ 3 mg/L处理‘阳光玫瑰’后,花后两周运用几种浓度梯度的CPPU搭配GA3 25 mg/L处理‘阳光玫瑰’可有效增大果实的纵横经、单果重以及可溶性固形物含量。花后两周将GA3与TDZ及CPPU三者混合处理‘阳光玫瑰’葡萄对于品质提升效果不好。综合各项因素考虑,花后以GA3 25 mg/L+CPPU2 mg/L处理效果较好。综合以上情况来看,于花前使用使用CPPU3mg/L处理‘阳光玫瑰’葡萄对于花穗拉长效果最好,可显著降低人工修果难度,降低工人成本。在花前两周用SM 200 mg/L处理‘阳光玫瑰’葡萄显著提高了果实无核率,有效提升了‘阳光玫瑰’综合品质。在盛花期以GA3 20 mg/L+TDZ 3 mg/L处理‘阳光玫瑰’,花后处理以GA3 25 mg/L+CPPU 2 mg/L混合使用对于提升‘阳光玫瑰’果实单果质量、可溶性固形物含量等方面效果较好。更多还原

【Abstract】 In this study,’Shine Muscat’ grapes were used as test materials to study the spike growth,seedless rate and fruit of ’Shine Muscat’ grapes under different treatment periods,different concentrations and different combinations between GA3,CPPU,SM and TDZ The impact of quality is expected to find ways to further improve the management efficiency and fruit quality of ’Shine Muscat’ grapes and provide some theoretical support for production.The findings are as follows:1.In the study of using different concentrations of CPPU to treat ’Shine Muscat’ grapes before flowering,the results show that CPPU treatment before flowering can improve the fruit length,horizontal diameter and single fruit quality of ’Shine Muscat’ grapes.With the increase of CPPU treatment concentration,treatment with CPPU 3 mg/L was the best.2.In the study of using different concentrations of SM to treat ’Shine Muscat’ grapes before flowering,the results show that each treatment can effectively increase the seedless rate of ’Shine Muscat’ grapes,up to 96.1%,and increase the soluble solid content of the fruit,Decrease the content of titratable acid,improve the effect of solid acid ratio is significant.At the same time,SM will reduce the single fruit quality of the fruit,not the higher the concentration,the better.Based on the above considerations,the comprehensive quality of’Shine Muscat’ grapes treated with SM 200 mg/L before flowering was better.3.In the research of using GA3,CPPU and TDZ to treat ’Shine Muscat’ grapes,the results show that after GA3 20 mg/L+TDZ 3 mg/L is used to treat ’Shine Muscat’,CPPU with different concentrations after flowering GA3 treatment of ’Shine Muscat’ can significantly increase the fruit longitudinal,horizontal warp,single fruit weight and soluble solid content.After flowering,the combination of GA3,CPPU,and TDZ at the same time was not effective in treating ’Shine Muscat’ grapes.Taking all factors into consideration,the effect of GA3 25 mg/L+CPPU 2 mg/L after flowering is better.In view of the above,using CPPU 3 mg/L before flowering to treat ’Shine Muscat’grapes has the best effect on flower ear elongation,which can significantly reduce the difficulty of artificial fruit repair and reduce labor costs.Treatment of ’Shine Muscat’ grapes with SM 200 mg/L before flowering significantly improved the seedless rate of the fruit,and the overall quality was better,which could effectively improve the overall quality.Treatment of ’Shine Muscat’ with GA3 20 mg/L+TDZ 3 mg/L in full bloom period,and treatment of ’Shine Muscat’ with GA3 25 mg/L+CPPU 2 mg/L two weeks after flowering can improve the fruit single fruit quality and soluble solid form The comprehensive effect of the content and other aspects is better.更多还原
