Dumpsite Aftereffects on Structural and Functional Integrity of Three Crop Weeds.

Title:Dumpsite Aftereffects on Structural and Functional Integrity of Three Crop Weeds Benjamin Aderemi Ajayi1, Akeem Babalola Kadiri 1& James Dele Olowokudejo1       University of Lagos, Department of Botany, Akoka Lagos, Nigeria.           Corresponding author: aderemibenjamin@gmail.com Plants that grow around dumpsites are exposed to various kinds of pollutants after the refuse has been burnt, thus leading to structural changes as a form of adaptation to the environment. Experiments were conducted in order to investigate functional and structural adaptive changes in leaves and roots of three invasive weeds commonly found in dumpsites in Lagos Nigeria, including Elusine indica, Digitaria horizontalis, and Phyllanthus amarus. Fresh leaves and roots were collected from varying distances to the polluted sites and were studied microscopically for the differences between the micro characters of the leaves and petioles. The plants studied showed significant changes in their foliar anatomy including reduced cell size, and dark-colored deposits in their epidermis and parenchyma cells, while the vascular bundles of the roots showed observable changes. These results highlight the importance of anatomical data for the diagnosis of injury and the sensitivity of roadside plants to different environmental pollutants.
