| Abstract | ||
| THE MEIOTIC behavior and morphology of pollen grains of four species of Asteraceae (Glebionis coronaria, Anacyclus monanthos, Matricaria recutita and cotula barbata) were studied. Glebionis coronaria, Anacyclus monanthos and Matricaria recutita showed nine chromosome bivalents while those of Cotula barbata showed eight chromosome bivalents. The chromosomes were meiotically identified as two pairs in three taxa (Glebionis coronaria, Anacyclus monanthos and Matricaria recutita) while it was one pair in Cotulabarbata.The pollen shape and morphology were recognized by measuring polar and equatorial axis, Morphological characteristics of the pollen grains of the four studied species were considerably different. | ||
