摘要
研究澳洲坚果叶片矿质元素含量与水分胁迫的关系,实验结果表明:不同水分胁迫程度下,随水分胁迫程度的加剧,叶片中含量降低的矿质元素有Zn、Ca、N、Mg和B,含量升高的矿质元素有K和Mn,水分胁迫对叶片中Co元素的影响不大,而P元素含量的变化不一致。水分胁迫时间与矿质元素含量的关系为:长期水分胁迫下,叶片矿质元素含量升高的有B和K,含量降低的有Ca、Mg、Mn、P、Zn和N,表现不一致的是Co。
It is studied the relation between the mineral content and moisture stress in the macadamia leaf. Underdifferent degree moisture stress, as moisture stress increase ,the contents of Zn,Ca,N,Mg and B depress, the contentsof K and Mn increase ,the Co content does not change largely, but the change of P content content disaccord.Under longmoisture stress,B and K contents increase,the contents of Ca,Mg,Mn,P,Zn and N element depress,the Co content isinconsistent.
