| 摘要: |
| 野生火棘在贵州省的资源分布广泛，由于省内各地区气候因子的不同，导致野生火棘果实的营养性成分存在差异。为探究贵州省野生火棘果的营养性成分差异，明确影响营养成分积累的气候因子，筛选出适宜生长区域，采用硫酸-苯酚法、全自动凯氏定氮仪、索氏提取法和福林-酚比色法对火棘果粗多糖、总蛋白、总脂肪和总多酚含量进行测定，并进行差异性分析、主成分分析和聚类分析；同时结合气候因子，进行灰色关联度的相关性分析。结果显示，不同产地之间4种营养成分含量存在明显差异，可将10个不同产地火棘分成3大类；灰色关联度分析表明，相对湿度是影响贵州野生火棘果营养成分含量的主要影响因子；降低相对湿度利于火棘果中营养性成分的积累。 |

| Abstract: |
| The resources of wild Pyracantha fortuneana （Maxim.） Li are widely distributed in Guizhou Province. Due to the different climatic factors in different regions of the province， the nutritional components of wild Pyracantha fruit are different. In order to explore the differences of nutrient components in wild Pyracantha fortuneana fruit in Guizhou Province， identify the climatic factors affecting the nutrient accumulation， and screen suitable growth areas， the contents of crude polysaccharide， total protein， total fat and total polyphenol were determined by sulfuric acid phenol method， fully automatic Kjeldahl nitrogen analyzer， Soxhlet extraction， and Folin-phenol colorimetry， and differential analysis， principal component analysis and cluster analysis were performed. At the same time， the correlation analysis of grey correlation degree was carried out combined with climate factors. The results showed that there were significant differences in the contents of four nutritional components from different producing areas. Pyracantha fortuneana fruits from 10 different producing areas could be grouped into three categories. Grey correlation analysis showed that relative humidity was the main factor affecting the contents of nutritional components of wild Pyracantha fortuneana fruits in Guizhou， and reducing the relative humidity facilitates the accumulation of nutrients in the fruits. |
