Pollen morphology of Calochortus Pursh and its systematic position in the Liliaceae family
Abstract
Pollen grain of eight species belonging to Calochortus were taken from the Herbarium in Komarov Botanical Institute of the Russian Academy of Science (RAN) and were studied by Light Microscopy (LM) and Scanning Electron Microscopy (SEM). Pollen grains of all the studied species were single, heteropolar, bilaterally symmetrical, distal-monosulcate, flattened-spheroidal to oblate, in outline with a pole rounded-elliptical, with the equator – flattened. Surface ornamentation of pollen in this species Corrugated – punching but in C. albus is punching – Corrugated. Palynolomorphological data showed that in Comparasion with other genera of Liliaceae, Calochortus is similar to some of species in Tulipa and Fritillaria. Cluster analysis revealed two main groups in the studied species. Therefore, present research has aided the Liliaceae family can be divided into 3 tribes as: Tulipeae, Calochorteae, Lloydieae.
