The aim of this study was to investigate the anatomical structure of the trunk wood and the roots of A. nitida and R. racemosa, two mangrove trees from Gabon. The anatomical differences between the trunks and the roots were used to understand their bio-remediating differences through heavy metals. It was found that the roots of A. nitida were less abundant in cells number/mm 2 than its trunk which exhibited the largest cells diameter. The roots and the trunk of R. racemosa didn't exhibit significant difference between their cells number. Nevertheless, the trunk of that mangrove tree displayed the largest cells diameter and somewhat traumatic channels. Any interspecies variability was found between their trunk vessels diameter. However, a significant difference was found regarding their vessels number/mm 2 , the trunk of A. nitida was richer in vessels compared to R. racemosa one. The roots of the latter were more abundant in vessels and they displayed the largest cells diameter than A. nitida. Broad parenchyma bands and sclerous cells lacked within R. racemosa while they were richer in A. nitida roots and trunk. The occurrence of those anatomical structures which storage substances was thought to act in the highest heavy metals bio-remediation of Avicenniaceae than Rhizophoraceae.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
