| 中文摘要: |
| 以1 a生枝条为试材，以当地传统硬籽石榴品种御石榴为对照，采用实验室模拟低温胁迫引起的相对电导率、可溶性糖等生理指标的变化，结合田间观测的结果，对12种软籽、半软籽石榴在渭北旱塬进行适应性综合评价。结果发现：13个石榴品种抗寒强弱顺序为御石榴＞宗山红＞铁炉红＞中榴2号＞中榴1号＞突尼斯半软籽石榴＞突尼斯软籽＞中农红软籽＞红如意软籽＞塔山软籽＞中榴8号＞淮北软籽2号＞淮北软籽1号；中榴2号、中榴1号、突尼斯半软籽石榴、宗山红、和铁炉红5个品种可替代渭北旱塬传统的硬籽石榴；突尼斯软籽石榴可在该地区背风向阳处栽种。 |
| 英文摘要: |
| One-year-old branches were used as experimental materials, and the traditional hard-seeded pomegranate cultivar ‘Yu Shiliu’ was used as the control. Laboratory simulations of low-temperature stress were conducted to examine changes in physiological indicators such as relative electrical conductivity and soluble sugar content, combined with field observations to comprehensively evaluate the adaptability of 12 soft-and semi-soft-seeded pomegranate cultivars in the Weibei Arid Plateau.The results showed that the cold resistance ranking of the 13 pomegranate cultivars was as follows: ‘Yu Shiliu’ > ‘Zongshan Hong’ > ‘Tielu Hong’ > ‘Zhongliu 2’ > ‘Zhongliu 1’ > ‘Tunisian Semi-Soft-Seeded Pomegranate’ > ‘Tunisian Soft-Seeded’ > ‘Zhongnong Hong Soft-Seeded’ > ‘Hongruyi Soft-Seeded’ > ‘Tashan Soft-Seeded’ > ‘Zhongliu 8’ > ‘Huaibei Soft-Seeded 2’ > ‘Huaibei Soft-Seeded 1’.Among these, five cultivars—‘Zhongliu 2’, ‘Zhongliu 1’, ‘Tunisian Semi-Soft-Seeded Pomegranate’, ‘Zongshan Hong’, and ‘Tielu Hong’—can serve as potential substitutes for the traditional hard-seeded pomegranate grown in the Weibei Arid Plateau. ‘Tunisian Soft-Seeded Pomegranate’ is suitable for cultivation in sheltered, sunny sites in this region. |
