Polygonum L. ve Rumex L.’ye (Polygonaceae) ait Bazı Taksonların Polen Morfolojisi ve Taksonomik Önemi

Abstract

Bu makalede, Polygonum L., Rumex L. (Polygonaceae)'den 12 takson ve Rumex scutatus L.'nin iki varyasyonu olmak üzere toplam 14 örneğin polen morfolojileri ışık mikroskobu ve SEM ile detaylı olarak incelenmiştir. Palinolojik bilgilerle bu türlerin taksonomik problemlerine çözüm aranmıştır. Palinolojik araştırmalar sonucunda Polygonum cinsine ait bazı taksonların polenleri incelenmiş; 3-kolpat, 3-kolporat, pantoporat, oblate-sferoidal, prolat, prolat-sferoidal, tektat, ekzin yüzeyi mikroekinat-perforat ve serbest kolumellalı retikulat yapıdadır. Rumex cinsine ait bazı taksonların polenleri; 3-kolporat, nadiren 4-kolporat, polen şekilleri oblat-sferoidal, suboblate, tektat ve ekzin yüzeyi mikroekinat-perforattır.

Pollen Morphology of Some Taxa Belonging to Polygonum L. and Rumex L. (Polygonaceae) and Its Taxonomic Significance

Abstract

In this article, the pollen morphologies of 14 samples in total, 12 taxa from Polygonum L., Rumex L. (Polygonaceae), and two variations of Rumex scutatus L. were studied in detail by light microscopy and SEM. Solutions to taxonomic problems of these species were sought with palynological information. Pollen grains of some taxa belonging to Polygonum are studied as a result of palynological research; 3-colpate, 3-colporate, pantoporate, oblate-spheroidal, prolate, prolate-spheroidal, tectate, and exine surface are microechinate-perforate and reticulate with the free-standing columella. Pollen grains of some taxa belonging to Rumex; 3-colporate, rarely 4-colporate, pollen shapes are oblate-spheroidal, suboblate, tectate, and exine surface are microechinate-perforate.
