嫁接是一种广泛应用于提高甜瓜对各种非生物和生物胁迫的耐受性，改善果实品质和作物产量的技术。甜瓜因其独特的味道和香气而成为世界各地受欢迎的葫芦科作物。提高甜瓜采后品质，延长货架期，对保证甜瓜市场供应具有重要意义。在这项研究中，我们评估了10种南瓜砧木嫁接的甜瓜在室温（25°C ± 2°C）和低温（10°C ± 1°C）条件下贮藏期间的采后果实品质。我们调查了几个生理，生化和抗氧化参数与采后水果品质。不同砧木、贮藏温度和贮藏时间对这些品质指标有明显影响。结果表明，以甜砧2号为砧木的甜瓜果实在室温下贮藏7 d后，其可滴定酸（0.21%）、苹果酸（0.84 mg/g）和总酚（15.96 mg/g）含量均低于其它嫁接组合。冷藏28 d后，银光砧木嫁接甜瓜果实可溶性固形物（15.40°）和蔗糖（169.30 mg/g）含量较高，而苹果酸（0.97 mg/g）和总酚（15.31 mg/g）含量较低。天珍2号嫁接甜瓜果实短期室温贮藏和长期冷藏后的综合品质指标均以隶属函数值0.67和银光砧木0.66居第一位。根据本研究结果，砧木的使用有助于保持采后果实在贮藏期间的品质，并延长甜瓜的货架期。因此，利用砧木沿着与其他采后贮藏技术可以是一个潜在的研究领域，以提高甜瓜果实的贮藏寿命。
Grafting is a technique widely utilized to enhance the tolerance of melon against various abiotic and biotic stresses and improve fruit quality and crop production. Melon is a popular Cucurbitaceae crop around the world due to its unique taste and aroma. Improved postharvest fruit quality with prolonged shelf-life is important to ensure the supply of melon in the market. In this study, we evaluated the postharvest fruit quality of melons grafted on ten pumpkin rootstocks during storage at room temperature (25°C ± 2°C) and cold conditions (10°C ± 1°C). We investigated several physiological, biochemical, and anti-oxidative parameters related to postharvest fruit quality. These quality parameters were evidently affected by the use of different rootstocks, storage temperature, and storage duration. The melon fruits obtained from Tianzhen No. 2 rootstock had no weight loss and relatively lower titratable acidity (0.21%), malic acid (0.84 mg/g), and total phenolic (15.96 mg/g) contents compared with other grafting combinations after 7 days of room storage. Moreover, Yinguang rootstock-grafted melon fruits showed relatively higher total soluble solids (15.40°) and sucrose (169.30 mg/g) but lower malic acid (0.97 mg/g) and total phenolic (15.31 mg/g) contents after 28 days of cold storage. The melon fruits grafted on Tianzhen No. 2 with membership function value (0.67) and Yinguang rootstock (0.66) ranked 1st regarding overall fruit quality attributes after short-term room-temperature and long-term cold storage, respectively. Considering the results of our study, the use of rootstock helped maintain the post-harvest fruit quality during storage and extended the shelf life of melons. Thus, the use of rootstocks along with other post-harvest storage techniques can be a potential research area to improve the storage life of melon fruits.
