Iron Exposure Effects on Seedling Growth of Enterolobium cyclocarpum (Jacq.) Griseb. and Albizia chinenesis (Osbeck) Merr on Water Culture Media

open access: yesInternational Journal of Forestry Research, Volume 2025, Issue 1, 2025.
Iron (Fe) is a trace element and metal crucial to plant growth and development. However, it can become toxic at high concentrations, potentially harming plants. Information related to the tolerance or sensitivity of forest plants to Fe exposure can be the basis for selecting species to be planted on land with high Fe content.
