Abstract:

The pollen grains of two genera (Allium and Calochortus) of Liliaceae (sensulato) family were investigated. Pollens were obtained from the Herbarium at Komarov Botanical Institute of the Russian Academy of Science (RAN) and different parts of Kermanshah region and compared with herbarium of Razi University of Kermanshah, Iran. Both genera were investigated using LM (Light Microscopy) and SEM (Scanning Electron Microscopy). According to LM and SEM, the pollen grains of genera were monad, monosulcate percolate, heteropolar with bilateral symmetry, which the sulcus extends from distal to proximal. Also sulcus membrane ornamentations in both genera were regulate-perforate or perforate-regulate but wall thickness and diameter of the perforations in the mesh networks in Calochortus were upper than Allium genus. According to this study the species of Calochortus can be divided into five subsections (elegant, nitidus, puchelli, gunnisoniani andvenusti). Although are Allium and Calochortus genera were belonging to Alliaceae and Liliaceae family respectively, but in morphology of the pollen grains were very similar and their differences were minimum. In comparison with the other genera of Liliaceae (sensulato) family, these genera (Allium and Calochortus) in term of morphology of pollen grains were similar to some species of Tulipa and Fritillaria (Liliaceae family)
