Pollen Morphology of Solanaceae in Jordan

Saleh Al-Quran

15 solanacean species were investigated palynologically by LM and SEM. Most of the examined species have 3-zonocolporate pollen class, except four species. They were, Hyoscyamus aureus L. (4-loxocolporate), Lycopersicon esculentum L. (4-loxocolporate), Mandragora autumnalis L. (4-loxocolporate) and Nicotiana tabacum L. Polar measurements ranges between (11.5-45.5) μm, Solanum dulcamara L. has the smallest polar measurements (11.5-13 μm), While Datura stramonium L. has the largest (40-45.5 μm). Equatorial measurements ranges between (11.5-51) μm, Solanum dulcamara L (11.5-13.5 μm) also has the smallest equatorial measurements while Datura stramonium (48-51 μm) has the largest. P/E ratio ranges between (0.83-1.32), Datura stramonium L. has the smallest ratio (0.83-0.89), while Nicotiana tabacum L. (1.32-121) has the largest. Pollen outline has been recognized, the equatorial view of all species examined was elliptic except two were circular (Datura stramonium L. and Solanum dulcamara L.); the polar view was angular for all solanacean species except three were circular (Datura stramonium L., Solanum dulcamara L. and Withania somnifera L. Dunal); P/E ratio has three views, suberect, subtransverse and semitransverse. The morphology of ectoaperture structures (colpi, fastigia and margins) have reflected distinguished variation, three species only exhibited short colpi, while the remaining twelve were not exhibiting, five species have indistinct ectoaperture margin, while the remaining ten have distinct margin. The morphology of endoaperture structures (colpi, costae and margins) have reflected also distinguished variation; seven species have short colpi, while the remaining eight species have long ones; four species have present costae, while the remaining eleven have abscent ones; eleven species have indistinct endoaperture margins, while the remaining four have distinct ones.
