A Contribution to the Pollen Morphology of Family Gramineae
نویسنده
چکیده
Pollen morphology of 20 species belonging to the 14 genera of the family Gramineae has been investigated using light microscope and scanning microscope. It is a stenopalynous in nature. Pollen grains mostly spheroidal, monoporate rarely diporate, ±circular, pores small operculate, non-operculate, annulate or non-annulate. Tectum areolate to scabrate. On the basis of exine ornamentations 5 distinct pollen types are recognized. Palynology do not correspond with tribal classification. However, palynology is significantly helpful at the specific and generic level within the tribes.

متن کاملA TAXONOMIC STUDY OF CORYDALIS SUBGENERA AND SECTIONS IN IRAN USING ANATOMIC AND POLLEN CHARACTERISTICS
The stem anatomy and pollen morphology of Iranian members of the genus Corydalis (except C. seisumsiana in pollen morphology) were studied using light and SEM microscopy. The results verified the argument that the tuberous sections of Corydalis, including Radix-cava, Corydalisand Leonticoides could be classified in a single subgenus as a natural grouping. The study also revealed that the specie...
متن کاملThe importance of palynology in the taxonomy of genus Silene, based on pollen morphology
In this study, the palynology of 33 species of Silene belonging to 15 sections was investigated to examine the correspondence between palynology, morphological sections and phylogenetic trees. The pollen grains were prepared using the acetolysis method. Quantitative and qualitative micromorphological features of pollens were investigated using light microscopy and scanning electron microscopy....
