以‘长芒仔’锥栗为试材，对其种仁发育期营养枝叶片、结果枝叶片及果实（种仁、刺苞、果皮 ＋ 种皮）中 N、P、K、Ca、Mg、Mn、Fe、Zn、Cu 矿质元素含量及果实不同组织质量变化进行分析。结果表明：坚果从幼胚发生期至成熟期为种仁发育的关键时期，坚果、种仁和淀粉干质量较前期都有显著增长，分别增加了 6.14 g（92.4%）、4.97 g（99.43%）及 3.82 g（99.92%）。在种仁发育期，营养枝及结果枝叶片中 Cu 含量呈显著下降变化，P、Zn 含量波动上升；果实刺苞中 Ca、Fe、Cu 含量显著下降，Zn 含量上升后下降，其余元素变化甚微；果皮 ＋ 种皮中 N、P、K、Mg、Cu 含量前期变化甚微，后期显著下降，...

In order to realize scientific fertilization and achieve high and stable yield, we investigated changes of main mineral elements （N, P, K, Ca, Mg, Mn, Fe, Zn, and Cu） in developing fruits i.e. kernel, prickly burs, and pericarp ＆ seed coat, and different type of leaves in ＇Changmangzi＇. In addition, dynamic changes of the weight of different tissues of the fruit were also measured. Compared to the embryo initiation stage, nut weight, kernel weight, and total starch weight in the kernel increased by 6.14 g （92.4%）, 4.97 g （99.43%）, 3.82...
