Abstract

The genus Tilia L. belongs to Malvaceae and it is represented by four species in Turkey. These are T. cordata, T. platyphyllos, T. rubra subsp. caucasica, and T. tomentosa. Tilia species have medicinal importance, especially to treat colds, flu, and coughs, and are also used as sedatives. Inflorescence with bract is recorded in the pharmacopeia as used parts. This study aimed to investigate the differences in leaf and bract characteristics in distinguishing Tilia species. Leaves and bracts were examined anatomically and micromorphologically under light and scanning electron microscopes (LM and SEM). There is no comparative anatomical and micromorphological study of Tilia species from Turkey. Microscopic examination allows for the observation of stomata types, trichomes, and other anatomical structures. These features can vary among species and can aid in differentiation. Features of bract that is medicinally used part were evaluated to find efficient diagnostic characters. The leaves also possess distinct characteristics, and leaf morphology is already used in the identification key in Flora. The emphasis is on identifying the species of medically used drugs. A diagnostic key was created using LM and SEM based on bract features to differentiate taxa for the first time.

Research Highlights

Leaf and bract anatomy of Tilia taxa was studied via LM and SEM.
The raw plant material is inflorescence with bract so identification by bract is important for species adulteration.
An diagnostic key based on bract features was created for the first time.

土耳其椴树物种的解剖学和微形态学及其分类学意义。

椴属属于锦葵科，在土耳其有四个品种。它们是 T. cordata、T. platyphyllos、T. rubra subsp.椴树具有重要的药用价值，尤其是治疗感冒、流感和咳嗽，还可用作镇静剂。花序和苞片在药典中被记录为使用部分。本研究旨在调查叶片和苞片特征在区分椴树物种方面的差异。在光镜和扫描电子显微镜（LM 和 SEM）下对叶片和苞片进行了解剖学和微观形态学检查。目前还没有对土耳其的椴树物种进行解剖学和微形态学比较研究。显微镜检查可以观察气孔类型、毛状体和其他解剖结构。这些特征在不同物种之间会有差异，有助于区分。为了找到有效的诊断特征，我们对苞片（药用部分）的特征进行了评估。叶片也具有明显的特征，叶片形态学已被用于《植物志》的鉴定关键中。重点在于识别药用植物的种类。根据苞片特征，首次使用 LM 和 SEM 创建了诊断密钥，以区分类群。研究亮点：通过 LM 和 SEM 研究了椴树类群的叶片和苞片解剖结构。椴树的原材料是带有苞片的花序，因此通过苞片进行鉴别对于物种掺假非常重要。首次创建了基于苞片特征的诊断密钥。
