Soluble Sugar and Mineral Contents of Sijiyou Pummelo during Development Period

摘要: 以四季柚为试材,跟踪测试果实发育过程中可溶性糖和矿质元素百分含量,分析两者之间的相关性,为树体营养调控和合理施肥提供理论依据。结果显示,果实发育过程中果肉可溶性糖含量8月中旬开始上升,果肉和果皮N、P、K、Ca、Mg、S百分含量均以幼果期最高,随着果实发育逐渐下降,但果实中各元素积累持续增加。果肉可溶性糖百分含量与单果K积累量呈显著相关。

Abstract: Contents of soluble sugars and minerals in the fruits of Sijiyou pummelo(Citrus grandis(L.) Osbeck) were determined.The correlation between them during fruit development could help better understand the nutritional regulation of and improve the fertilization practice for the plant.It was found that,during the development of the fruits,the soluble sugars in the flesh increased in mid-August,and all major components accumulated continuously.On the other hand,the contents of N,P,K,Ca,Mg and S in the flesh and peel decreased gradually.A significant correlation appeared to exist between the contents of soluble sugars in flesh and the accumulated K of the individual fruit.
