用原子吸收光谱法对大马士革玫瑰枝、叶中Ca、Mg、Fe、Cu、Mn 5种微量元素的含量进行了测定,并研究了不同生理条件、不同器官中5种元素含量的动态变化规律。结果表明:大马士革玫瑰枝叶中含有丰富的Ca、Mg、Fe、Cu、Mn微量元素,元素含量高低顺序依次为:Ca>Mg>Fe>Mn>Cu;玫瑰叶片中的微量元素含量均明显高于枝条,甚至较枝条要高出一个数量级以上;未开花植株和开花植株微量元素含量的动态变化规律总体上基本相似,但是未开花植株的微量元素含量要显著低于开花植株;在生长季节内,5种微量元素含量各呈现不同的动态变化规律,这与植物的生长发育和元素的植物生理功能密切相关。
The contents of five trace elements Ca, Mg, Fe, Cu and Mn in rose branches and leaves of Damascus were determined by atomic absorption spectrometry. The dynamic changes of five elements in different physiological conditions and organs were studied. The results showed that the leaves and leaves of Damascus rose were rich in trace elements Ca, Mg, Fe, Cu and Mn. The order of elements was Ca> Mg> Fe> Mn> Cu. The contents of trace elements in rose leaves were significantly higher Branches, and even more than the branches to an order of magnitude more than the non-flowering plants and flowering plants trace elements in the dynamic changes of the law is generally similar, but the flowering plants were significantly lower than the content of trace elements in flowering plants; in the growing season, The contents of five trace elements show different dynamic changes, which are closely related to plant growth and development and plant physiological functions.
