| 摘 要： | 以“黄金梨”和“鸭梨”为试材,分析了叶片和果实中主要矿质元素含量年变化及其二者间的相关关系.结果表明:叶片内氮、磷、钾含量随叶龄增长而降低,钙含量随叶龄增长而升高,镁则前期增加,后期减少；果实中氮、磷、钾、钙、镁含量随果实膨大而呈递减趋势.“黄金梨”叶片和果实中氮磷钾含量高于“鸭梨”.“黄金梨”叶片中氮磷含量和果实中氮磷含量呈显著正相关,镁则呈负相关.

| Abstract: | The changes of five mineral element contents and correlation among them in the leaves and fruits of 'Whangkeumbae' and 'Yali' pear were studied.The results showed that the contents of nitrogen,phosphorus,and potassium in the leaves manifested a decreasing tendency in growing season.The content of calcium showed increasing tendency,and the content of magnesium increased in early period and decreased in late period.The content of nitrogen,phosphorus,potassium,calcium,and magnesium in fruits manifested a decre... |
