不同南瓜品种果实品质性状的比较试验

Comparative Trials of Different Pumpkin Cultivars for Fruit Quality

以8个优良的南瓜品种为研究对象,测定其成熟果实的硬度、含水量、可溶性固形物、维生素C、蛋白质、纤维素、β-胡萝卜素等7项品质指标。结果表明,南瓜富含可溶性固形物、β-胡萝卜素;果实硬度大,耐贮运;不同品种间差异较大,蜜本41号和昌德蜜本的综合营养品质较好,而蜜橙品种的综合品质则较差。

Fruits of 8 desirable pumpkin cultivars were determined in quality traits such as firmness, water content, soluble solids content, vitamin C, protein content, fiber content and β- carotene content to assess their fruit quality. The results showed that these pumpkin cultivars were high in the contents of soluble solids and be- ta-carotene, good in firmness and stored well. There are significant differences in nutritional composition among different pumpkin cuhivars. Pumpkin Miben 41 and Changde Miben had a higher while Pumkin Micheng had a lower nutritional quality.
