摘要
为比较杂交种和常规种之间矿质元素钙、铁、锌的含量,本试验选取张杂谷5号、张杂谷13号、晋谷21号、晋谷59号为试验材料,用火焰原子吸收光谱和方差分析比较4种谷子钙、铁、锌元素的含量,结果表明:4种谷子的钙元素含量存在极显著差异(P<0.01),晋谷21号的钙元素含量极显著高于其他3种谷子,但晋谷59号与张杂谷5号不存在差异;4种谷子的铁元素含量存在显著差异(P<0.05),张杂谷5号的铁元素含量显著高于晋谷59号,晋谷59号与张杂谷13号不存在差异;4种谷子的锌元素含量不存在差异(P>0.05)。在杂交谷的产量远远高于常规谷的条件下,杂交谷的矿质元素含量并不比常规谷差,为大面积推广杂交谷提供理论依据。
In order to compare the contents of calcium, iron and zinc in the mineral elements between conventional and hybrid fox tail millet, this paper select Zhangzagu No.5, Zhangzagu No.13, Jingu No.21 and Jingu No.59 as experimental materials. The content of calcium, iron and zinc in four kinds of foxtail millet was determined by flame atomic absorption spectrometry. The contents of calcium, iron and zinc in four kinds of foxtail millets are compared by analysis of variance. The results show that there is extremely significant differences in the calcium content of the four kinds of foxtail millet(P<0.01). The calcium content of Jingu No.21 is significantly higher than the other three kinds of foxtail millet, but there is no difference between Jingu No.59 and Zhangzhagu No.5. The difference of the iron content of the four kinds of foxtail millet is significant(P<0.05), and the iron content of Zhangzagu No.5 is significantly higher than that of Jingu No.59. There is no difference between Jingu No.59 and Zhangzagu No.13. There is no difference in the zinc content of the four foxtail millet seeds(P>0.05). Under the condition that the yield of hybrid foxtail millet is much higher than that of conven-tional foxtail millet, the content of mineral elements in hybrid foxtail millet is not worse than that of conventional foxtail millet. It provides a theoretical basis for large-scale promotion of hybrid foxtail millet.
