Title

Micromorphology and anatomy of achene in Thalictrum in Iran

Pages

  30-42

Abstract

 A comprehensive micromorphological and anatomical study was carried out on achene of five species and 1 variety from Thalictrum Tourn. ex L. using scanning electron microscopy and hand sections to evaluate achene characteristics for use in the examination of systematic relationships. Considerable differences were found in achene micromorphology and anatomy both among the species and variety. Exocarp was ribbed and the shape of exocarp cells was either papillate, reticulate, ruminate, and reticulatepapillate. In addition, the number of fibre cells, collenchymas, schlerenchymas, and parenchyma were important characteristics for distinguishing the taxa. A phenogram from statistical analysis based on nine quantitative anatomical traits showed that, varieties of T. minus have different anatomical characters and are similar to T. tacabicum. Besides, the present data convincingly support a close relationship between T. isopyroides and T. foetidum more than other species. On the other hand, T. sultanabadense with lesser vascular bundles and curved achene showed less similarity with other species. This study is congruent with the earlier groupings of the Thalictrum species based on morphology and agrees in part with molecular studies. The results of this study showed that, the anatomical features of the achene due to the provision of diagnostic traits could be useful for identifying and isolating species of this complex genus.
