摘要 以8年生釀酒葡萄品種“赤霞珠”為試驗材料,在葡萄轉色期7月下旬到8月上旬噴施SA,探究在果實發育中SA對果實品質的影響,為改善釀酒葡萄品質提供參考。結果表明,對葡萄葉面噴施SA,整個生長周期“赤霞珠”百粒重無顯著差異,葡萄進入轉色期后,各SA處理下葡萄果實中糖類物質均逐漸增加,有機酸含量逐漸減少,采收期時,糖類物質含量達到最高,有機酸含量達到最低。采收期(花后110 d),5 mmol/L SA處理可以明顯降低葡萄中可滴定酸含量,3 mmol/L SA處理可以顯著提高葡萄果實中糖類物質和酚類物質含量。3 mmol/L SA處理有利于“赤霞珠”葡萄果實品質的改善。

Abstract Eight-year-old wine grape variety ‘Cabernet Sauvignon’ was sprayed with SA from late July to early August during the grape color transformation period to explore the effect of SA on fruit quality during fruit development, to provide reference for improving wine grape quality. The results showed that there was no significant difference in 100-seed weight of ‘Cabernet Sauvignon’ during the whole growth period when the grape was sprayed with SA, the content of organic acid decreased gradually. At harvest time, the content of carbohydrate reached the highest and the content of organic acid reached the minimum. 5 mmol/L SA treatment at harvest time (110 days after anthesis) could significantly reduce the content of titratable acid in grape fruit, while 3 mmol/L SA treatment could significantly increase the content of carbohydrate and phenol in grape fruit. The SA treatment could improve the quality of ‘Cabernet Sauvignon’ grape fruit.

水楊酸作為植物體內重要的內源信號分子和酚類物質,SA在植物體中扮演著不可或缺的角色,對于植物生長發育有著眾多積極的作用和效果[1-3]。水楊酸的應用為提高葡萄抗性、促進果實品質和葡萄果實的生長提供了更多的可能。近年來,釀酒葡萄品種在我國得到大力發展,北方與西北地區是當前我國釀酒葡萄的主要產區,其中寧夏賀蘭山東麓已成為我國重要的釀酒葡萄優質生態產區之一[4]。
