摘要
[目的]了解无融合生殖核桃果实的矿质营养水平。[方法]用原子吸收分光光度仪测定不同时期果实中7种矿质元素含量。[结果]在所测矿质元素中,除Cu、Zn元素外,无融合生殖果实中K、Ca、Mg、Fe、Mn诸元素含量均低于对照;除Fe元素外,其他各元素在无融合生殖果实中的含量在年周期中都呈下降趋势,且无融合生殖果实比对照下降的要多。[结论]无融合生殖果实比自然授粉受精果实矿质营养水平低,致使其不能正常生长发育成熟。
[ Objective ] The purpose was to know the mineral nutrient level in apomictic walnut fruit. [ Method] Seven mineral nutrient con- tents of walnut fruit were determined during different growing periods by using atomic absorption speetrophotometer. [ Result] The contents of K, Ca, Mg, Fe, Mn in apomictic fruits were lower than the control except Cu and Zn. Except Fe, their contents in the apomictie walnuts were decreased gradually in the year cycle, and the decreased contents were more greatly than the control. [ Conclusion] The mineral nutrient level in apomictic walnut fruit was lower than natural pollination and fertilization fruits, which resulted in walnut fruit could not develop and mature normally.
