A palynological survey of the genus Scrophularia L. (Scrophulariaceae) from Turkey
Abstract Pollen morphology of 73 taxa belonging to the genus Scrophularia L. (Scrophulariaceae) distributed in Turkey is examined with light microscopy (LM) and scanning electron microscopy (SEM) to determine their properties and assess their taxonomic significance. The pollen grains of Scrophularia are radially symmetrical and isopolar. Their shape is oblate-spheroidal, suboblate, and prolate-spheroidal, with the polar axis ranging from 16.56 µm to 32.88 µm and the equatorial axis ranging from 18.24 µm to 35.52 µm. The aperture type is usually trizonocolporate but is rarely tetracolporate and trisyncolporate. Four types of exine ornamentation are observed: microreticulate, reticulate, microreticulate-rugulate, and suprareticulate. Numerical analysis reveals that pollen dimensions and exine sculpturing are the most useful diagnostic variables for discriminating Scrophularia taxa. Results also show a partial relationship between the Scrophularia taxa clustered on the basis of pollen morphology and the systematics of these taxa on the basis of general macromorphology.
期刊介绍:
Grana is an international journal of palynology and aerobiology. It is published under the auspices of the Scandinavian Palynological Collegium (CPS) in affiliation with the International Association for Aerobiology (IAA). Grana publishes original papers, mainly on ontogony (morphology, and ultrastructure of pollen grains and spores of Eucaryota and their importance for plant taxonomy, ecology, phytogeography, paleobotany, etc.) and aerobiology. All submitted manuscripts are subject to initial appraisal by the Editors, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. All peer review is single blind and submission is online via ScholarOne Manuscripts.
