Pollen morphology of some Alyssum L. (Brassicaceae) from Turkey

Abstract

The present study evaluated the taxa A. linifolium Stephan ex. Willd. var. teheranicum Bornm., A. simplex Rudolph, A. trichocarpum T.R. Dudley & Hub.-Mor., A. armenum Boiss., A. praecox Boiss. & Bal., A. lepidoto-stellatum (Hausskn. &Bornm.) T. R. Dudley, A. sulphureum T. R. Dudley & Hub. - Mor., A. murale Waldst. & Kit. subsp. murale, A. pateri Nyar. subsp. pateri of the genus Alyssum L. from the family Brassicaceae in terms of palynological characteristics. Samples of these taxa were collected in field studies. 9 taxa from this genus were examined using light microscope (LM) and scanning electron microscope (SEM). Results of the study revealed some common characteristics such as tectate pollens, subprolate, prolate shapes of pollens, heteropolar symmetry. Aperture type was tricolpate. SEM microphoto also indicated that ornamentation structures were reticulate.
