[目的]研究榛子果实发育过程矿物质的动态变化。[方法]研究3个榛子杂交品系果实发育中,氮、磷含量的动态变化规律。[结果]幼果迅速发育期和果仁发育期是榛子果实吸收、累积矿质元素的关键期。3个杂交品系中,氮素的变化规律为前期下降—中期平缓—后期快速增加,磷素的变化规律为前期下降—中期稳定—后期先快速增加,后快速下降。[结论]该研究为保证榛子果实发育中营养元素的合理补充提供理论依据。
[Objective] The research aimed to study the dynamic changes of minerals during the fruit development of hazelnut. [Method] The dynamic changes of nitrogen and phosphorus contents in the fruit development of three hazelnut hybrids were studied. [Result] The rapid development of young fruits and the development of nuts were the key period for absorbing and accumulating mineral elements in hazelnut fruits. Among the three hybrids, the variation of nitrogen decreased from early prophase to mid-term and then rapidly increased at the later stage. The change of P decreased from early prophase to mid-term, then rapidly increased at the later stage and then decreased rapidly. [Conclusion] The study provided the theoretical basis for ensuring the rational supplementation of nutrients in the fruit development of hazelnut.
