In this work the principal elements (K, Ca, Fe, Mg, Cu, Zn, Mn, Na) constituting the mineral component of the pollen in some Gymnospermae, have been determined. This type of investigation has few matches in literature despite the importance some mineral elements have in germinating the pollen granule. The pollen samples, appropriately treated, were analysed in atomic absorption spectrophotometry and biometrically characterized under the optical microscope. Examination of the analytical data allows verification of the great influence deriving from soil characteristics and, within the families, a specific role of the type. The morphobiometric parameters show that a link exists between small and medium granules and with thin walls and minimum concentration values of Na, Fe, Cu, Zn and Mn.
在这项工作中,已测定了一些裸子植物花粉矿物成分中的主要元素(钾、钙、铁、镁、铜、锌、锰、钠)。尽管某些矿物元素对花粉粒萌发很重要,但这类研究在文献中很少见。对经过适当处理的花粉样本进行了原子吸收分光光度法分析,并在光学显微镜下进行了生物特征表征。对分析数据的检查证实了土壤特性产生的巨大影响,以及在科内类型的特定作用。形态生物特征参数表明,中小颗粒与薄壁以及钠、铁、铜、锌和锰的最低浓度值之间存在联系。
