| Title : | MICROMORPHOLOGY OF POLLEN GRAINS FROM BISEXUAL AND FUNCTIONAL MALE FLOWERS OF POMEGRANATE |
| Abstract : | Modern taxonomy uses pollen grain morphology as an important tool due to its specific and diverse features. Pomegranate is an andromonoecious species having two type flowers on the same plant, in other words, hermaphrodite flowers (bisexual) and male flowers (functional male flowers) that develop on the same plant. The length of polar axis (P) and the equatorial diameter (E) as well as P/E ratio of pollen grains, collected from both bisexual and functionally male flowers of the cultivar ‘Caner I’, were analyzed using scaning electron microscopy (SEM). The length of polar axis (P), the equatorial diameter (E), and P/E ratio was compared between the two grain. The sculpturing pattern of the exine of both type flowers was striate, with more parallel longitudinal ridges Pollen from both bisexual and functional male flower types is similar in size (≈21 μm). In contrast to the divergent pistil development observed between bisexual and functional male pomegranate flowers, no differences in pollen morphology were detected. The pollens had prolate shape (P\E=1.65 vs 1.59) in both types of flowers. |
