华山梨生长期矿质元素含量的变化

Changes of Mineral Nutrient Elements in Growing Period of Whasan Pear

对华山梨叶片和果实中矿质元素含量的年变化进行了研究,结果表明:叶片内N、P、Cu含量随叶龄增加而降低,Ca、Mn、Mg含量随叶龄增加而升高。果实中N、P、Ca、Mg、Mn、Cu含量随果实膨大而呈递减趋势。叶片和果实中Fe,Zn含量变化波动较大。

This paper reported the seasonal changes of nine mineral element contents in the leaves and fruits of Whasan pear. The results showed that the contents of N,P,Cu in the leaves manifested a decreasing tendency in a year, while the content of Ca,Mn,Mg showed increasing tendency. The content of N,P,Ca, ,Mg,Mn,Cu in fruits manifested a decreasing tendency from setting fruit to harvesting. The contents of Fe and Zn in leaves and fruits changed largely .
