- Abstract:
- Taking the ‘Cabernet Sauvignon’ grape at different altitudes in different basins of Shangri-La as test materials,the reducing sugar,total acid,total phenolics,tannin and total anthocyanins content of the grape were determined from the development stage to the mature stage.To provide a theoretical reference for the production of high-quality and characteristic grapes and wines in Shangri-La and other high-altitude regions of the world,the differences in fruit quality and the accumulation law of basic quality indexes were discussed during the development period of the grape at different altitudes in the Jinsha River Basin and Lancang River Basinto provide a theoretical reference for the production of high-quality and characteristic grapes and wines in Shangri-La and other high-altitude regions of the world.The results showed that the longer duration of sunshine,UV radiation,and the larger temperature difference made great contribution to the grapes at Liutongjiang vineyard (located at about 2 121 m above sea level) with the highest sugar content,the lowest total acid.The sugar content was 265.16 g·L-1,while total acid content was 4.01 g·L-1.In addition,the content of total phenolics,tannin and total anthocyanins of the Dari vineyard (about 2 238 m) were the highest (8.58 mg·g-1,11.54 mg·g-1 and 160.53 A520·g-1,respectively) in all sampling vineyards.The soluble solids and sugar content of grape in all sampling vineyards of Jinsha River and Lancang River Basin showed an increasing trend,and the total acid content increased first and then decreased.The rapid accumulation period of reducing sugar content and rapid decline period of total acid content of the Jinsha River Basin (Waka and Dari) were generally about two weeks earlier than the Lijiang River Basin (Xidang,Sinong,and Adong).Meanwhile,the content of total phenolics,tannin,and total anthocyanins increased with the increasing of altitude between 2 000-2 250 m in both Basins.They reached their maximum values respectively at the sampling vineyards of 2 250 m in both Basins (Dari and Sinong).But as the vineyard′s altitude increased again,the content of total phenolics,tannin decreased again at Adong vineyard (2 602 m),and total anthocyanins of Adong vineyard had no significant change.The accumulation of total phenols and tannins in Waka and Dari in the River Basin during the period from four weeks to 16 weeks after flowering was different from the Lancang River Basin,and the period during which the maximum was reached was also different.This might be due to the fact that the terroir of the Liutongjiang vineyard in Lancang River Basin was similar to those in the Jinsha River Basin,the quality indexes,especially the reducing sugar and total acid,had a similar accumulated pattern during the development period.
