摘要

毛状体微形态可以作为种和亚种分离的判别特征。五种黄颡鱼属植物(T. scordium subsp.)叶片毛状体的微形态学特征。用扫描电镜对scordium、T. sirnakense、T. chasmophyticum、T. andrusi和T. spinosum进行了研究。鉴定出7种类型的毛状体,包括腺状和非腺状。腺毛分为三种类型;短棍棒状,长棍棒状和近无柄。非腺毛可分为四种类型;单细胞薄壁,2(5)细胞薄壁,3-7(11)细胞弯曲,细长薄壁和2细胞厚壁毛。除棘叶外,叶片两侧的毛状体类型基本相似。近无柄腺毛是最常见的类型,在所有被调查的物种中都存在。除T. scordium亚种外,所有种均有棒状腺毛。scordium。所有种类的毛状体都具有明显的厚壁特征,而只有裂藓属的毛状体呈薄壁特征。本研究也首次详细报道了T. sirnakense和T. chasmophyticum的叶片微形态。

Leaf indumentum in some Turkish species of Teucrium (Lamiaceae)
DOI : 10.5152/IstanbulJPharm.2018.374759 Trichome micromorphology can be used as a discriminating character in the separation of species and subspecies. The micromorphological characteristics of foliar trichomes from five Teucrium taxa (T. scordium subsp. scordium, T. sirnakense, T. chasmophyticum, T. andrusi and T. spinosum) were investigated by scanning electron microscope. Seven types of trichomes were identified, including glandular and non-glandular. The glandular trichomes were recorded in three types; short clavate, long clavate, and subsessile. The non-glandular trichomes were identified with four types; unicellular thin-walled, 2(5)-celled thin-walled, 3–7(11)-celled flexuose, elongated thin-walled and 2-celled thick-walled trichomes. Generally, the trichome types were similar on both sides of the leaves, except in T. spinosum. Subsessile glandular trichomes were the most common type and were occurred in all the investigated species. Also clavate glandular trichomes were found in all the species, except T. scordium subsp. scordium. All trichomes were distinctively thick-walled, whereas thin-walled trichomes were observed in only T. chasmophyticum species. The leaf micromorphology of T. sirnakense and T. chasmophyticum has also been reported in detail for the first time in this study.
