渭北旱塬老藤酿酒葡萄资源的品种特性研究
Research on Cultivar Characteristics of Old Vine Resources of Wine Grape in Wei Bei Arid Region
摘要
Abstract
To protect and develop the old vine resources of wine grape in the Wei Bei arid region,this study systematically compared the botanical characteristics,growth and development habits,cane uprightness,cold resistance,berry characteristics,and winemaking properties of Muscat Blanc and Muscat Rouge,two old vine resources of wine grape.The results showed that both Muscat Blanc and Muscat Rouge possessed strong and upright canes.Compared to Cabernet Sauvignon,the width of xylem in new shoots was significantly greater and the distribution area of lignin was wider.This improved the mechanical performance and load capacity of canes,making them suitable for non-trellis cultivation.Additionally,Muscat Blanc and Muscat Rouge had high budburst rates,fruiting shoot rates,fruiting coefficients and average yield per plant,suggesting their good productivity.Both Muscat Blanc and Muscat Rouge showed strong resistance to low temperatures and,therefore,did not require burying in soil to protect against winter cold in the Wei Bei arid region.The study also found that Muscat Blanc berries had light green skin with a slight red blush,a reducing sugar content of 195.17 g·L-1,and a titratable acidity of 5.97 g·L-1 at the mature stage.These berries had a low content of phenolic compounds,making them suitable for producing refreshing dry white wine.The matured berries of Muscat Rouge had purple-red skin,a reducing sugar content of 208.33 g·L-1,and a titratable acidity of 3.64 g·L-1.These berries had a high content of phenolic compounds,making them suitable for producing fresh rose wine.Lastly,the dry white wine made from small containers showed an alcohol content of 11.12％(V/V),a total acidity of 5.06 g·L-1,and a total sugar content of 2.70 g·L-1.The rose wine had an alcohol content of 12.97％(V/V),a total acidity of 4.69 g·L-1,and a total sugar content of 2.87 g·L-1.The grape berries and produced wines of the two old vine resources had a rose flavor.The results of this study provide some guidance for the breeding of wine grape cultivars.关键词
