Abstract

In this study we report the palynological properties of the genus Reseda, which is represented by 18 native taxa in Turkey. In general terms, pollen grains are monad, isopolar, radially symmetrical, oblate-spheroidal to subprolate in equatorial view, circular in polar view, small or medium sized and tricolporate. Pollen grains of R. malatyana are oblate-spheroidal; those of R. alba, R. coodei, R. balansae, R. orientalis, R. anatolica, R. lutea, R. globulosa, R. tomentosa var. tomentosa, R. tomentosa var. glabrata, R. germanicopolitana var. germanicopolitana, R. aucheri subsp. rotundifolia and R. luteola are prolate-spheroidal. Pollen grains of R. armena var. scabridula, R. minoica, R. germanicopolitana var. glabra and R. saadae are subprolate. All pollen grains of the examined Reseda taxa except R. orientalis are small in size. The mean polar axis length is 15.92–29.12 μm, the mean equatorial axis length is 14.20–26.88 μm and the mean amb diameter is 13.30–25.54 μm. The aperture bears a colpus at the top and a pore underneath the colpus. Its membrane is granulate under light microscopy. The margin of the colpus is distinct, whereas that of the pore is indistinct. The exine structure is semitectate, and the sculpture is microreticulate. In terms of details of exine sculpturing, two pollen types are observed: Reseda alba type and Reseda luteola type, or (in other words) reticulate type and rugulate type. It was not possible to separate sections or species of the examined Reseda taxa based on pollen data. The morphological and palynological data should be evaluated together to understand the classification of the genus Reseda in Turkey.

摘要

在这项研究中，我们报告了Reseda属的孢粉学特性，该属由土耳其的 18 个本地分类群代表。一般而言，花粉粒为单子体，等极，径向对称，赤道观为扁球体至近扁长，极观为圆形，小或中型，三孔。的花粉粒R. malatyana是扁圆球形; 那些R.粉，R. coodei，R.南岭，R.侧柏，R. anatolica，R.球菌，R. globulosa，R.毛白杨变种 毛白杨，R.毛白杨变种。光滑的, R. Germanicopolitana var. Germanicopolitana , R. aucheri subsp. R. rotundifolia和R. luteola是扁长球状的。R. armena var. 的花粉粒。scabridula，R. minoica，R. germanicopolitana变种。glabra和R. saadae是 subprolate。除R. orientalis外，所检查的Reseda分类群的所有花粉粒体积小。平均极轴长度为 15.92-29.12 μm，平均赤道轴长度为 14.20-26.88 μm，平均 amb 直径为 13.30-25.54 μm。孔在顶部有一个锥体，在锥体下方有一个孔。其膜在光学显微镜下呈颗粒状。丘脑边缘明显，而孔边缘不明显。外壁结构为半棱柱状，雕塑呈微网状。在外壁雕刻的细节方面，观察到两种花粉类型：Reseda alba型和Reseda luteola型，或（换句话说）网状型和皱纹型。无法分离受检Reseda 的部分或物种基于花粉数据的分类群。形态学和孢粉学数据应一起评估，以了解土耳其Reseda属的分类。
