PALYNOLOGICAL STUDY OF POLLEN GRAINS OF ARTEMISIA VULGARIS PLANT

This article represents for the first time in the Albania’s palynological literature information about data on the palynological characteristics of pollen grains of Artemisia vulgaris plant, Compositae family. The results obtained are shown compared with the palynomorphological features of Artemisia absinthium and Artemisia caerulescens taken by the Albanian literature. Pollen grains of the plant of Artemisia vulgaris were collected in fresh conditions to the Elbasan area. By making comparison among the main palynological characteristics of pollen grains of these plants showed that there are similarities in terms of pollen grains shape to three plants, the number of furrows and pores but at the same time there are also changes related to the size of pollen grains, furrows and diameter of pores. These changes are a consequence of the ecological factors and pollen grains processing method. Based on the results obtained by this study, by comparison made between pollen grains studied species showed that larger proportions of pollen grains in length, width and the diameter of the pores represent those of Artemisia vulgaris. Width of furrows in pollen grains of Artemisia vulgaris is thinner than the other two plants. The layer of exine at Artemisia vulgaris is thinner than Artemisia caerulescens and slightly thicker than Artemisia absinthium. The sculptures of exine of pollen grains of the three types is accompained by small granules but especially, the pollen grains of Artemisia vulgaris are accompanied by microspinules.
