摘要
为研究喀什红枣果实主要营养物质间的相关性,以5年生喀什‘灰枣’和‘骏枣’为对象,测定成熟期果实矿质元素、总糖、总酸和维生素C含量。‘灰枣’和‘骏枣’果实主要矿质元素含量顺序均为:钾>氮>钙>磷>镁>铁>锌>铜>锰>硼。测定的13个营养物质指标中铁、镁、钾、磷、氮、维生素C和总酸7个指标的含量‘骏枣’极显著高于‘灰枣’,钙和总糖2个指标的含量‘骏枣’与‘灰枣’无差异;硼、锌、铜、锰4个指标的含量‘灰枣’较‘骏枣’高,但无显著差异。果实的矿质元素、总糖、总酸和维生素C共13个指标的72组相关性数据中,‘灰枣’72组全部存在相关性,其中35组具有显著相关性;‘骏枣’有71组数据存在相关性,其中30组具有显著相关性。喀什‘灰枣’和‘骏枣’果实中矿质元素、总糖、总酸和维生素C等因子之间是既有协同作用,又有相互抑制,果实品质形成是各营养物质协同调控的结果。
The purpose of this project was to study the correlation of fruit nutrients（mineral element, totalsugar, total acid and Vc） of‘Huizao＇and‘Junzao＇in Kashi, Xinjiang. The ripening fruits of 5 years old‘Huizao＇and‘Junzao＇were used as materials to determine the content of mineral elements, total sugar, totalacid and Vc. The results showed that the order of the main mineral elements was KNCaPMgFeZnCuMnB in both‘Huizao＇and‘Junzao＇fruits. 7（Fe, Mg, K, P, N, Vc and total acid） of 13 indicators in‘Junzao＇were significantly higher than that in‘Huizao＇. The contents of Ca and total sugar in‘Junzao＇werealso higher than that in‘Huizao＇but did not reach the significant levels. However, the contents of B, Zn, Cuand Mn in‘Huizao＇were higher than that in‘Junzao＇, but did not reach the significant levels. All 72 pairs ofdata from 13 indicators in‘Huizao＇were correlated. Among them, 35 pairs were correlated significantly. In‘Junzao＇, 71 out of 72 pairs data were correlated, among them 30 pairs were correlated significantly.Collaboration and suppression coexisted among mineral elements, total sugar, total acid and Vc in the fruits of both‘Huizao＇and‘Junzao＇. Fruit quality was the result of coordinated regulation of various nutrients.
