Abstract

 

In this study Leucojum ionicum was considered in two habitats never studied before: Dhërmi and Palasë. The morphological and histological traits were studied, and comparison between these two populations was made. The technique used for the analysis of epidermal structures is the standard technique of nail polish, which consists in obtaining stomatal traces in the upper and lower epidermis. From the analysis of morphological traits it resulted that in both habitats L. ionicum appears with the same morphological traits only with small differences in leaf area. Comparing the distribution of stomata, was observed variation between the two populations. In Palasa individuals, distribution of stomata results a little bit higher than in Dhërmi individuals. SI (stomatal index) and SD (stomatal density) results higher in Palasa population with small differences from Dhermi population. We encountered also variation in stomatal morphology. Stomata in individuals of Dhërmi population appears larger in size and with angles being more distinct than stomata in the individuals of Palasa population. This explains the reason why the population of Palasa had a higher number of stomata/field.
