酿酒葡萄媚丽在不同气候区的适应性及果实品质研究

通过调查媚丽在暖热半湿润区（陕西杨凌地区、白鹿原地区和河南民权县）；暖温半干旱区（陕西合阳县和山西夏县）；中温干旱区（内蒙古乌海市）共6个地区的栽培特性及果实品质，评估其在这些地区的适应性。结果表明，采收时果实含糖量最高的为夏县媚丽（211.74 g/L），最低的为杨凌媚丽（177.59 g/L）。乌海媚丽的果皮总花色苷含量和单宁含量均为最高，分别为15.29 mg/g和17.03 mg/g，民权媚丽的总花色苷含量最低，为2.10 mg/g，夏县媚丽的单宁含量最低，为6.86 mg/g。总花色苷/单宁比值最大的为乌海媚丽（0.56），最低为民权媚丽（0.11）。以暖热半湿润区的杨凌地区作对照综合分析，媚丽在其他气候区的适应性最好的是乌海，最差的是民权。

Adaptability and quality of wine grape Meili in different climate zones

The study aimed to assess the adaptability of wine grape Meili in 3 climate zones, warm hot sub-humid zone (Yangling, Shaanxi; Bailuyuan, Shaanxi and Minquan, Henan), warm semi-arid zone (Heyang, Shaanxi and Xiaxian, Shanxi) and mid temperature-arid zone (Wuhai, Inner Mongolia). The results were showed that, the reducing sugar contents of Xiaxian Meili fruit was the highest of 211.74 g/L at harvest, the lowest one was Yangling Meili with 177.59 g/L. The total anthocyanin and tannin contents of Wuhai Meili peel were the highest and they were 15.29 mg/g and 17.03 mg/g, respectively. The contents of total anthocyanin of Minquan Meili was the lowest of 2.10 mg/g, and the tannin contents of Xiaxian Meili was the lowest of 6.86 mg/g. Total anthocyanin/tannin ratio of Wuhai Meili was the highest of 0.56, and total anthocyanin/tannin ratio of Minquan Meili was the lowest of 0.11. From comprehensive analysis, compared with Yangling region (warm hot sub-humid zone), the most adaptive region of Meili in other climate zones was Wuhai (mid temperature-arid zone), and the worst one was Minquan (warm hot sub-humid zone).
