以‘突尼斯’、‘宁津三白酸’、‘峄城三白甜’3个石榴栽培品种1年生枝为试材,进行不同低温处理,测定了相关半致死温度、脯氨酸等生理指标,并综合分析了隶属函数。结果表明:3个石榴品种的抗寒性为‘峄城三白甜’>‘宁津三白酸’>‘突尼斯’,即‘突尼斯’为不抗寒品种,‘宁津三白酸’为中抗寒品种,‘峄城三白甜’为抗寒品种。
The 1-year-old branches of 3 pomegranate cultivars from Tunisia, Ningning Trimesic Acid and Tancheng Sanbaitei were used as test materials for different low-temperature treatments and physiological indexes such as semi-lethal temperature and proline , And a comprehensive analysis of the membership function. The results showed that the cold resistance of three pomegranate cultivars was Tancheng Sanyitian, Ningjin Trimethoprim, Tunisia, that is, Tunisia was not cold-tolerant and Ningjin tricaprate was In the cold-resistant varieties, ’Tancheng three white sweet’ for the cold-resistant varieties.
