银杏种子生长发育过程中营养元素含量相关性分析

研究并分析了银杏种子中氮、磷、钾、钙、镁、锌、铁、锰等８种营养元素之间相互影响，相互作用的关系。结果表明，银杏种子中各种营养元素间存在显著的线性相关关系，相关系数均达到极显著水平，多元素间的加合效应大于单一元素的作用；不同营养元素两两间的相互作用各有其特点，氮与磷、钾、镁间相互促进，钙与钾呈正相关，而与氮，磷呈负相关，微量元素锌、铁相互促进，锰则妨碍对锌的吸收。

CORRELATION BETWEEN NUTRITION ELEMENTS DURING GROWTH AND DEVELOPMENT OF Ginkgo biloba SEEDS

This article studied the mutual effect and interaction among the eight mineral nutrition elements in Ginkgo biloba seeds such as N,P,K,Ca,Mg,Zn,Fe,Mn. The result shows that there are distinct linear correlative relations among nutrition elements. All correlation coefficients reach the upmost distinct level. The synergetic effect of multi-elements is greater than that of the single etements. The interaction of different pairs of nutrition elemerts has its own characters. The interaction between N and P,K,Mg is mutually advanced and that between Ca and K is of possitive correlation, but there is negative correletion between Ca and N,P. The micronutrients Zn and Fe accelerate each other, but Mn impedes the absorption of Zn.
