| 中文摘要: |
| 本研究调查分析了内蒙、青海、宁夏、新疆、甘肃五省的7个不同枸杞产地的宁夏枸杞的果实外观形态以及枸杞多糖、总糖含量的差异；结合当地气象数据，分析了气象因子与枸杞果实外观形态的相关性，并采用主成分分析法对7个产地枸杞果实外观形态指标进行统计分析，对不同产地枸杞果实大小进行了排名。结果表明：青海诺木洪农场、甘肃白银市靖远县和新疆精河县的枸杞果实较大，而宁夏银川和中宁产枸杞较小；海拔和平均温度是影响枸杞果实形态的主导因子，海拔越高，平均温度越低则果实越大、越长；宁夏中宁县所产枸杞的枸杞多糖的含量最高，达到了7.525 g·100g-1，显著高于其它产地（P＜0.05），但总糖含量最低；内蒙杭锦后旗、青海诺木洪农场和内蒙乌拉特前旗3个产地枸杞果实的总糖含量较高。该研究结果，将为药用枸杞栽培和种植区域的定位提供理论依据，为综合评价不同枸杞产区枸杞的品质提供数据基础。 |
| 英文摘要: |
| The indexes of Lycium barbarum, morphological characteristics of fruits,and varieties of polysaccharide and total sugar contents from five provinces, Inner Mongolia, Qinghai, Ningxia, Xinjiang and Gansu with seven different producing areas in Ningxia, were investigated and analyzed. Based on the local meteorological data, the correlation between the meteorological factors and the morphological appearance of Lycium barbarum fruit was analyzed, and fruits’ appearance indexes in seven producing areas were estimated using the principal component analysis, the fruit sizes were ranked. The results showed that the fruit of Nuomuhong farm, Jingyuan county and Jinghe county were relatively large, while Yinchuan and Zhongning county were relatively small. The altitude and mean temperature were the main factors influencing the fruit morphology . The higher the altitude, the lower the mean temperature, resulted in the bigger and longer the fruit; The fruit produced in Zhongning county of Ningxia had the highest content of polysaccharide reaching 7.525 g·100g-1, which was significantly higher than that in other areas (P<0.05), but the content of total sugar was the lowest. The content of total sugar in the fruit was higher in Inner Mongolia Hangjinhouqi, Nuomuhong farm of Qinghai and Wulateqianqi of Inner Mongolia. The findings would not only provide the theoretical basis for the positioning of medicinal Lycium barbarum cultivation and planting area, but also provide a data base for the comprehensive evaluation of Lycium barbarum quality in different wolfberry producing areas. |
