Abstract In this study, the morphological, genetical (molecular) and elemental compositions of morphologically similar three endemic Lathyrus L. species such as L. phaselitanus Hub.-Mor. & Davis, L. lycicus Boiss. and L. belinensis N. Maxted & D. J. Goyder belong to genus Lathyrus in Turkey were investigated. In the morphological part, some important parameters such as stem shape, plant height, leaflet number, leaflet length, leaflet width, stipule shape, stipule length, stipule width, fruit length, fruit width, fruit shape, number of flowers and standard were investigated. In the genetical part of the study, chloroplast intergenic spacer trnH-psbA was used to reveal the genetic diversity and phylogenetic relationship among the three endemic Lathyrus species to decide whether they were systematically similar or not. Additionally, the concentration of some elements such as Nickel (Ni), Iron (Fe), Copper(Cu), Cadmium (Cd), Chromium (Cr), Manganese (Mn), Magnesium (Mg), Zinc (Zn), Sodium (Na) and Potassium (K) were also determined by flame atomic absorption spectrometry to observe the similarities and/or differences among these three endemic Lathyrus species based on elemental composition. The results revealed that there was also a genetic similarity of 99% between morphologically similar L. belinensis and L. lycicus species but they were previously placed in different sections.

三种地方性 Lathyrus L. 物种的分子和元素特征及分类学说明

摘要 在这项研究中，形态学上相似的三种地方性 Lathyrus L. 物种，如 L. phaselitanus Hub.-Mor. 的形态、遗传（分子）和元素组成。＆戴维斯，L. lycicus Boiss。和 L. belinensis N. Maxted & DJ Goyder 在土耳其属于 Lathyrus 属。在形态学部分，对茎形、株高、小叶数、小叶长度、小叶宽度、托叶形状、托叶长度、托叶宽度、果实长度、果实宽度、果实形状、花数、标准等重要参数进行了考察。 . 在研究的遗传部分，叶绿体基因间间隔trnH-psbA用于揭示三种地方性Lathyrus物种之间的遗传多样性和系统发育关系，以确定它们是否系统相似。此外，某些元素的浓度，例如镍 (Ni)、铁 (Fe)、铜 (Cu)、镉 (Cd)、铬 (Cr)、锰 (Mn)、镁 (Mg)、锌 (Zn)、钠 (Na ) 和钾 (K) 还通过火焰原子吸收光谱法测定，以观察基于元素组成的这三种地方性 Lathyrus 物种之间的相似性和/或差异性。结果表明，在形态相似的 L. belinensis 和 L. lycicus 物种之间也存在 99% 的遗传相似性，但它们之前被放置在不同的部分。钠 (Na) 和钾 (K) 也通过火焰原子吸收光谱法测定，以观察基于元素组成的这三种地方性 Lathyrus 物种之间的相似性和/或差异性。结果表明，在形态相似的 L. belinensis 和 L. lycicus 物种之间也存在 99% 的遗传相似性，但它们之前被放置在不同的部分。钠 (Na) 和钾 (K) 也通过火焰原子吸收光谱法测定，以观察基于元素组成的这三种地方性 Lathyrus 物种之间的相似性和/或差异性。结果表明，在形态相似的 L. belinensis 和 L. lycicus 物种之间也存在 99% 的遗传相似性，但它们之前被放置在不同的部分。
