Multiplicação in vitro e aclimatização de Melocactus sergipensis

Abstract: Multiplicação in vitro e aclimatização de Melocactus sergipensis ä Resumo-Melocactus sergipensis é uma espécie recém-descoberta, endêmica do estado de Sergipe e criticamente ameaçada de extinção. O objetivo desta pesquisa foi estabelecer um protocolo para micropropagação e aclimatização de plantas de M. sergipensis. O experimento foi instalado em delineamento inteiramente casualizado, com quatro tratamentos, 10 repetições e em cada unidade experimental foi introduzido um explante. Os explantes foram obtidos de… Show more

“…Indeed, for the combination of auxin and cytokine to be effective, there must be a balance between them, ie doses that are sufficient to induce the rooting process without causing toxicity to the explant, which would lead to callus formation. The combined use of auxin and cytokine was also favorable to root development in other species, such as M. sergipenses (coroa-de-frade) (Bravo Filho et al, 2018). However, the results are not always the same or similar, since the response depends on several other factors, such as explant type and age and nutritional condition of the donor plant.…”

“…Five Melocactus species are found in the Brazilian state of Sergipe, where they occur in the coastal Restinga ecosystem and the semi-arid Caatinga biome. Melocactus sergipensis Taylor & Meiado, is the state's only endemic cactus, and is the only cactus species classified as Critically Endangered in the IUCN Red List (Taylor et al 2014, Zappi et al 2016, Bravo Filho et al 2018, based on criteria B1, B2, and C2 (IUCN 2001). In , Bravo Filho et al (2015 recorded a population of approximately 100 adult M. sergipensis growing on outcrops of granite and metamorphic rock within a small patch of Caatinga vegetation of approximately 1000 m 2 (Taylor et al 2014, Herbário Alexandre Leal Costa 2016.…”
