Evaluation of the chemical composition of aquatic environments with leaf litter decomposition of Eucalyptus urophylla S.T. Blake (Myrtaceae) and their toxicity in Allium cepa L. (Amaryllidaceae)
Abstract:Allelochemicals from eucalyptus released into the environment, mainly by leaves, can have a toxic effect on local biota, including in aquatic environments. Therefore, the present study evaluates the toxic activity of the water containing leaves of Eucalyptus urophylla S.T. Blake (Myrtaceae) in decomposition using Allium cepa L. (Amaryllidaceae) as a test organism. The toxicity and the cytotoxicity evaluation were performed using onion bulbs (A. cepa). The toxicity was assessed by inhibiting root growth. The cy… Show more
