MORPHOLOGICAL STUDY OF POLLEN GRAINS OF THE GENUS TORILIS ADANS. FROM THE FAMILY APIACEAE WILD GROWING IN IRAQ.

Abstract

The current research aims to study a morphological taxonomic study of the pollen grains of the taxa Torilis genus wild growing in Iraq. Nine taxonomic taxa belonging to the genus were diagnosed and separated T. arvensis, T. chrysocarpa, T. heterophylla, T. leptocarpa, T. leptophylla, T. leptophylla var. erythrotricha, T. nodosa, T. stocksiana and T. tenella, the mattresses were all of the same poles and isopolar with simple apertures in the form of colpate or Porate grooves. All taxa were three holes or grooves Tricolpate. Pollen grain was of the type Zono colpate as the grooves of pollen do not extend from the pole to the second pole and do not connect the grooves end with each other. The pollen grains differed in their shapes, dimensions and the nature of their surfaces, and there is a discrepancy between the nature of the surface decoration of the studied genus taxa. It is concluded from the foregoing that all these variations are taxonomic evidence to isolate the studied genus taxa.
