摘要

Pollen morphology of 11 species of family Fabaceae that is, Trifolium alexandrinum, Trifolium resupinatum, Arachis hypogaea, Lathyrus aphaca, Medicago lupulina, Vicia sativa, Lathyrus odoratus, Pongamia pinnata, Melilotus indicus, Medicago polymorpha, Medicago sativa from Pakistan has been investigated by light and scanning electron microscopy. Pollen were generally tricolporate, radially symmetrical, isopolar, elliptic in equatorial view and triangular in polar view under LM. Results showed that pollens were per-prolate (T. alexandrinum), prolate (T. resupinatum, V. sativa, L. odoratus, Melilotus indicus, M. polymorpha, M. sativa) and sub-prolate (A. hypogaea, L. aphaca, M. lupulina, P. pinnata). The larger polar/equatorial (P/E) ratio was found in T. alexandrinum (2.26 mu m) and the smallest was found in M. lupulina (1.21 mu m). The exine of T. resupinatum was 3.00 mu m in thickness while others posses smaller exine thickness. The larger pore diameter was found in P. pinnata (16.01 mu m) while others have smaller. The length of colpi was larger in Arachis hypogaea (32.24) while others posses smaller. Eight types of surface ornamentation (Psilate, faintly rugulate). Perforate and rugulate to verrucate have been observed under SEM. The pollens were europalynous type. Pollen morphology proved to be useful for the specific delimitation and serve as a tool for the identification and classification of taxa at specific and generic levels and can also be used as a key for the taxonomic features. Diversity in exine sculpture is helpful indicative characters for the isolation of closely related species. Hence, it is clear that both qualitative and quantitative characters of pollen can be useful for differentiating between taxa at specific level.

Odoratus，Melilotus Indemus，M. polymorpha，M. sativa）和亚脯氨酸（A. hypogaea，L. Aphaca，M.Lupulina，P.Pinnata）。在T.Alexandrinum（2.26μm）中发现较大的极性/赤道（P / E）比，最小的是在M. Lupulina（1.21μm）。 T. resupinatum的外部厚度为3.00亩，其他有其他膨胀厚度。在P.Pinnata（16.01μm）中发现较大的孔径，而其他孔径较小。在阿拉氏腹腔内（32.24）的Colpi的长度较大，而其他有可能更小。八种类型的表面装饰（Psilate，微弱的恶毒）。在SEM下观察到穿孔和毒硬于疣。花粉急诊型。花粉形态被证明是对特定划界有用，并作为在特定和通用水平识别和分类的工具，也可以作为分类学特征的关键。外来雕塑的多样性是有用的指示性状，用于隔离密切相关的物种。因此，很明显，花粉的定性和定量特征可用于区分特定水平的分类。
