| Abstract |
In this study, morphological information is produced as evidence for proper delimitation of Senna occidentalis (L.) Link taxonomy. The field work was carried out during the growing season of 2008 in order to follow up the morphology of vegetative and reproductive growth of studied species throughout the successive stages of its entire life span. Germination of seeds and yield components at harvest time were also taken in consideration. Such knowledge may fulfill information acquisition in this concern. The morphology of vegetative growth includes: plant height, length and diameter of the main stem, number of internodes of the main stem, number of primary branches developed on the main stem, lengths of primary branches at maturity, fresh weight of leafless shoot per plant, total number of leaves per plant, total leaf area per plant and fresh weight of leaves per plant. Moreover, keen observations and descriptive morphology of the root and the shoot were under consideration. The morphology of reproductive growth includes: flower bud differentiation, full blooming, fruit set and maturity. In addition, the yield characters at harvest time were investigated; i.e., number of matured dry pods per plant, number of seeds per pod, number of seeds per plant, yield of matured dry seeds per plant and specific weight of seeds. |
