Abstract：
Diguo (Ficus tikoua Bur.), an ancient wild fruit, is widely spread in southwest China. However, there is little information on the phenotypic traits, quality characteristics, and aroma compounds available to diguo fruit. The present study is an investigation into the effects of geographical origin on the phenotypic traits and quality characteristics of wild diguo fruit collected from southwest China. The volatile compounds in the mixed fruit samples were also investigated using gas chromatography-mass spectrometry. Our results indicated that significant variation existed among the sampling materials in all the phenotypic parameters. Fruit fresh weight ranged between 2.06 and 4.59 g. Moreover, significant variation existed among the selected materials in all macronutrients (dry matter, total soluble solids, crude protein, crude fat, and ash) and some nutritional parameters (glutamate, arginine, total soluble solids, maltose, and mannose, etc.). Regardless of their geographical origin, diguo fruit is relatively low in fat and fructose and high in fiber and glutamate. A total of 95 volatile constituents were identified in the frozen diguo fruit. In conclusion, diguo fruit with rich nutritional attributes has a promising future for commercial-scale production. The variability of the observed morphological and nutritional features of diguo fruit provides important characteristics for improving the breeding of diguo as a modern fruit crop.
摘要：
迪果(FicustikouaBur.),一种古老的野生水果，在中国西南地区广泛传播。然而,关于表型特征的信息很少，质量特性,和迪果果实可用的香气化合物。本研究是对中国西南地区野生地果果实表型性状和品质特征的影响的调查。还使用气相色谱-质谱法研究了混合水果样品中的挥发性化合物。我们的结果表明，在所有表型参数中，采样材料之间存在显着差异。水果鲜重在2.06至4.59g之间。此外，在所有大量营养素(干物质，总可溶性固体，粗蛋白，粗脂肪，和灰分)和一些营养参数(谷氨酸，精氨酸总可溶性固体，麦芽糖,和甘露糖,等。).不管他们的地理起源，地果果实的脂肪和果糖含量相对较低，纤维和谷氨酸含量较高。在冷冻的地果果实中总共鉴定出95种挥发性成分。总之,具有丰富营养属性的地果果实具有商业化生产的前景。观察到的地果果实形态和营养特征的变异性为改善地果作为现代水果作物的育种提供了重要特征。
