榛子果仁发育中矿质元素的累积规律研究

摘要

选取3个榛子杂交品系,研究榛子果仁发育中矿质元素的动态变化.结果表明,从果仁发育期开始到果实完全成熟,单个果仁中N、P、K、Ca含量逐渐上升.果仁发育期和充实期是榛子果仁吸收、累积矿质元素的关键期,矿质元素增长速率累积值达到70%以上.%The variation dynamic of mineral elements of kernel during the development period was studied in three crossbreds of hazelnuts. The results showed that the contents of nitrogen, phosphoms, potassium and cadmium in single kernel increased continually from the kernel development stage to the fruit complete maturity stage. The kernel development and filling stage were the critical periods for the absorption and accumulation of mineral elements, the accumulation rate of mineral elements was beyond 70％ at this stage.
