Nutrição de Adenium spp. (Apocynaceae): uma revisão bibliográfica

Abstract

The desert rose (Adenium spp.) has been gaining space in the ornamental plant market, due to its bonsai-like appearence. Belonging to the Apocynaceae family, native to tropical Africa, in the southern region of the Sahara, from Senegal to Sudan and Kenya passing through Arabia, being introduced and naturalized in diferent parts of the world, as well as in Brazil. Mineral nutrition has a direct influence on several quality aspects of ornamental species, such as height, shape and color of plants and flowers, becoming an important aspect in the managment of exotic plants, for which systematized information is not available. As a methodology for this work, an exploratory bibliographical review was chosen, making it possible to analyze the discussions of authors who have already worked with the theme in question,with emphasis on a theoretical analysis of the conduct of the studies, with the objective of systematizing information about the mineral nutrition of desert roses. Of a total of 41 scientific articles published between 2011 and 2023, available in the CAPES, Scopus, Science Direct and Web of Science databases on desert rose production, eight articles were analyzed in depth. The result of the synthesis shows that the nutrition of Adenium spp., an ornamental plant on the rise, is an area lacking in research, with uncertainties regarding the contribution of nutrients such as nitrogen, ammonia, nitrate, sodium and potassium, as well as the interaction with the manganese and other macronutrients. Although the reviewed studies indicate that Adenium spp. has a good ability to use avaliable nutrients, the importance of micronutrients such as copper, iron and boron was not addressed. Given the growing importance of this plant in the ornamental plant market, it is crucial to carry out indepth research in the field of nutrition to ensure adequate fertilization, optimizing development and avoiding unnecessary expenses. It is recommended to invest in further studies to fill in the knowledge gaps and provide accurate and effective fertilization guidelines for this rising species.
