Keyword:  牡丹元素含量盆栽地栽相关性;
Abstract: 为了比较盆栽和地栽方式的差异,以牡丹品种洛阳红为试材,测定了盆栽和地栽方式下不同生长期牡丹叶、新茎、老茎三部位的氮、磷、钾、钙、镁、铁、锰、铜、锌元素含量,并分析了同一部位年周期内各元素间的相关性.结果表明:元素含量在同一器官呈现一定的相关性.盆栽和地栽牡丹的叶片中相关元素对最多,其中氮与磷、铜,磷与锌,钙与铁,铜与锌的含量表现出显著或极显著正相关;其次为新茎,相关性一致的元素对有磷与钾(呈显著或极显著正相关),磷与钙(显著负相关).但盆栽牡丹钾与钙的含量呈显著负相关,而在地栽牡丹新茎中钾与钙呈显著正相关,出现了差异.在老茎中,盆栽牡丹和地栽牡丹元素之间的相关性也出现了较大的差异.
