摘　　要：为探讨赤霉素在酿酒葡萄花序拉长上的处理时间和浓度,以美乐葡萄品种为试材,在花前22天(花序分离前期)、花前19天(部分花序分离期)和花前16天(花序完全分离期)进行20、30、40 mg/kg赤霉素处理,通过测定处理后果穗长度、果粒质量、果实糖酸及次生代谢物质含量筛选适宜的处理浓度和时间。结果表明,花前22天30 mg/kg赤霉素处理对花序拉长效果显著,且增加了果实次生代谢物质多酚、单宁、类黄酮、黄烷醇和总花色苷的含量。In order to find out the optimal spraying time and concentration of gibberellin on wine grape for inflorescence elongation,the variety Merlot was used as material,and three concentrations of gibberellin(20,30 and 40 mg/kg)were designed for spraying at 22 days before flowering(early stage of inflorescence separation),19 days before flowering(inflorescence separation)and 16 days before flowering(inflorescence complete separation).The results showed that,spraying 30 mg/kg gibberellin at the early stage of inflorescence separation significantly increased the length of bunch,total phenol,tannins,flavonoids,flavanols and total anthocyanin of Merlot grape.
