以大棚栽培的早熟温州蜜柑‘宫川’为试材,研究了果实发育及延迟采收过程中果实品质与抗氧化能力的变化。结果表明,延迟采收期间果皮、囊瓣皮部分占全果的比例维持一个较低水平,而汁囊所占比例相对较高。延迟采收提高了果实蔗糖、总糖、可溶性固形物、总类胡萝卜素和总黄酮的含量,并提高了果实的抗氧化能力,而可滴定酸含量则下降。但过迟采收,果皮、囊瓣皮占果实的比例上升,果皮增厚,相应地汁囊占果实的比例下降,果实的葡萄糖、果糖含量急剧下降,类胡萝卜素、总黄酮含量和抗氧化能力也略有下降。以上结果表明,延迟采收是提高果实品质的有效措施,但延迟采收期不宜迟于1月中旬,过迟则品质下降。 The early maturity Wenzhou satsuma ’Miyagawa’ cultivated in greenhouse was used to study the changes of fruit quality and antioxidant capacity during fruit development and delayed harvesting. The results showed that the percentage of pericarp and pericicle during the postharvest harvest period was low, while the percentage of juice sac was relatively high. Delayed harvesting increased the content of sucrose, total sugar, soluble solids, total carotenoids and total flavonoids, increased the antioxidant capacity of fruit and decreased the titratable acid content. However, after harvesting too late, the proportion of pericarp and pericarp increased, the pericarp became thickened, the proportion of juice sac in fruit decreased, the content of glucose and fructose in fruit decreased sharply, the contents of carotenoids, total flavonoids and antioxidation Capacity also declined slightly. The above results show that delayed harvesting is an effective measure to improve fruit quality, but delayed harvesting period should not be later than mid-January, then the quality will be reduced.
