摘要
以8个酿酒葡萄品种的一年生枝条为试材,测定不同低温胁迫下葡萄枝条电导率和可溶性糖含量2个指标,并进行抗寒性分析。结果表明:随着处理温度的降低,各品种枝条的相对电导率、可溶性糖含量逐渐升高,递增的速度和幅度存在一定差异,且递增幅度大小与抗寒性强弱一致;根据相对电导率、可溶性糖含量增幅大小不同可知,"威代尔"、"黑比诺"、"赤霞珠"和"霞多丽"抗寒性较强,"梅鹿辄"和"品丽珠"抗寒性较弱,其它品种抗寒性居中。
Annual dormant branches of 8 wine grape cultivars were used as test materials,to measure the electrical conductivity and soluble sugar content under low temperature stress and analysis the freezing tolerance.The results showed that,with the temperature decreased and the soluble sugar content in their branches were gradually increased,but the change speed and range were significantly different among varieties.The order of species parameters consistent with the cold resistance.‘Vidal＇,‘Pinot Noir＇,‘Cabernet Sauvignon＇and ‘Chardonnay＇showed greater cold-resistance ability,but the‘Merlot＇and‘Cabernet Franc＇were weaker in all species and the other varieties were in the middle.
