摘要
为了解瓜蒌中矿物质元素的分布及与土壤的相关性,以瓜蒌及其生长土壤为实验材料,采用光谱法初步测定了瓜蒌果核、果皮、茎叶以及其生长土壤中的Cu、Zn、Mn、Fe、Ca、Mg、K、Na元素含量.结果为瓜蒌中富含人体必需的矿质元素,果实各组织及其与土壤中元素之间存在相关关系(P<0.05,P<0.01),果实组织对土壤中元素具有一定的富集能力,尤其是茎叶对Ca、Mg、K的富集系数分别为1.23、0.98和2.93.果实中矿物质元素存在组织分布特点和区域分布差异,多数元素差异具有显著性(P<0.05),变异系数最大为49.4%.种植环境对瓜蒌品质存在较大的影响,进一步研究瓜蒌矿物质元素与环境的关系对提高品质和药效具有重要意义.
In order to get a clear picture about the distribution of the mineral elements in snakegourd fruit and its correla- tion with the soil, using the snakegourd fruit and its growth soil as experimental materials, the contents of the elements like Cu, Zn, Mn, Fe, Ca, Mg, K, Na in its core, peels, leaves and the soil, were determined by atomic absorption spectrometry. The result showed that the snakegourd fruit was rich in mineral elements essential to the human body; the elements in different tissues of the fruits and the soil , had correlation（P〈0.05 ,P=0.01）, and the peels , core, leaves had some accumulation abil- ity of the elements in the soil, especially the accumulation ability of leaves for the Ca, Mg, K, in which the accumulation coeffi- cient was 1.23, 0.98 and 2.93 respectively. The mineral elements in the fruits had tissue distribution and regional distributing difference, in which most of the element differences were significant（P〈0.05）, and the largest RSD was 49.4 %. The planting environment had significant influence on the quality of the snakegourd fruit, and further study on the relationship between the mineral elements in the snakegourd fruits and the environment, had obvious significance for the improvement of the quality and medical efficacy.
