| Abstract | ||||
| This study aimed to find out the morphological and anatomical differences in the stem among three genera of Solanaceae, namely; Solanum tuberosum L. (potato), Capsicum annuum L. ( pepper) and Datura stramonium L. (datura). Results revealed that Datura stramonium plants gave the highest measurements in plant height, stem diameter, and fresh and dry weights of leafless shoots, followed by Capsicum annuum, while Solanum tuberosum gave the lowest measurements in these characters, except in plant height where Capsicum was the lowest. Although Datura plants were the highest in plant height, it was the lowest in number of internodes. On the contrary Solanum recorded low measurements for plant height but was the highest in number of internodes. The structure of the stem indicated that, Solanum had the thickest second, median and basal internodes due to the thickness of vascular cylinder and pith, while Capsicum gave the most thin second and median internodes, and Datura was the most thin in the basal one. | ||||
