摘要(Abstract)：
以采收后的高妻、佳利酿、田野红3个成熟葡萄品种为试材,采用外源喷施法研究了水杨酸(Salicylicacid,SA)对葡萄果皮白藜芦醇(Resveratrol,Res)含量的影响;采用裂区试验对比研究不同品种、不同紫外线种类、同一紫外线不同辐射剂量对葡萄果皮Res含量的影响。结果表明,100mg/L的SA喷施处理可以显著提高3个葡萄品种果皮中的Res含量,诱导田野红的Res合成的效果显著高于高妻和佳利酿。除UV-B处理对高妻果皮中Res含量无显著影响外,其他UV-B和UV-C处理均能导致采后3个品种的葡萄果皮中Res含量的显著增加,且UV-C对Res诱导积累效果极显著地优于UV-B。辐射剂量在0～3.6kJ/m2范围内,3个葡萄品种果皮Res含量有随UV-B和UV-C辐射剂量的增加而增大趋势,但不同紫外线种类和辐射剂量对Res诱导积累效果因品种不同存在差异。
