外源钙对‘金太阳杏’果实品质的影响

Effect of exogenous calcium on the quality of gold-sun apricot fruits

以生产上主栽品种‘金太阳杏’为研究试材,通过外源喷钙处理,研究钙处理对果实可溶性固形物含量、单果重、可溶性糖含量、可滴定酸含量和矿质元素含量的影响。结果表明:钙处理提高了果实可溶性固形物含量、可溶性糖含量、Vc含量、果实硬度和钙含量,降低了磷和铁的含量,但对单果重、铜和锰的含量影响不大。

by sprinkling the gold-sun apricot fruits which was cultivated in production in a large scale with exogenous calcium, the author studied the effects of calcium on soluble solid content（SSC）, single fruit weight, soluble sugar content, organic acid content and the contends of mineral elements. Results showed the exogenous calcium improved the contents of SSC, soluble sugar, Vc, fruit hardness and content of mineral element Ca, decreased P and Fe contents. Single fruit weight, Cu and Mn contents had no difference.
