RESUMO:

The Amazon Forest is expanding rapidly over the Cerrado, due to environmental and climatic conditions. In order to understand the strategies, the appearance of plants in the face of climate change, characteristics were analyzed, specifically morphological, anatomical and hydraulic. Here, we aim to investigate the hydraulic functioning of transitional (Cerrado-Amazonian) plants in comparison with plants from the Amazon savannah, a goal of sense of relationship and coordination of structure/function between leaf and wood. In addition to answering the following questions: (i) Do transitional plants present attributes in the leaf and in the wood that converge to xeromorphism when compared to species from the Amazon savannah? (ii) Which delivery plans do they present that reflect a safe hydraulic system based on leaf and wood coordination, which enable the indication for forest restoration? The botanical material was processed according to standard plant anatomy techniques. Subsequently, analyzes were performed under an optical microscope to guide the morphoanatomical attributes. The attributes that they grouped as species of SA and one of the transitional plants are related to less water loss through leaves and greater safety in water transport, for example, greater wood density for this group of species. In contrast, transitional plants reflect more transpiration on the leaves. Based on our morphoanatomical study, we provide evidence that confirms a promoter species for forest restoration, only Enterolobium schomburgkii among the five transitional plants indicated by Arguelho (2021) due to the clear presence of attributes that converge to xeromorphism.
