Botanical studies on Phaseolus vulgaris L. I-morphology of vegetative and reproductive growth

Abstract

In this study morphological information is produced as evidence for proper delimitation of Phaseolus vulgaris L. taxonomy. The field work was carried out during the summer season of 2009 to follow the vegetative and reproductive morphology of studied plant throughout the successive stages of its entire life span. Germination of seeds and yield components at harvest time was also under consideration. Such knowledge may fulfill information acquisition in this concern. The morphology of vegetative growth includes: plant height, length of the main stem, number of internodes of the main stem, length and diameter of successive internodes of the main stem, number of secondary branches developed per plant, lengths of secondary branches of mature plant, fresh weight of leafless shoot per plant, dry weight of leafless shoot per plant, number of leaves per plant, total leaf area per plant, fresh weight of leaves per plant and dry weight of leaves per plant. Moreover, keen observations and descriptive morphology of the root and shoot system were under consideration. The morphology of reproductive growth includes: flower bud differentiation, full blooming, fruit set and maturity, fresh weight of reproductive organs and dry weight of reproductive organs. 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, dry weight of pods per plant, yield of matured dry seeds per plant and specific weight of seeds. © 2010 Asian Network for Scientific Information.
