“…However, adventitious root formation can also occur through xylogenesis, the genetic control of wood formation, and involves the expression of a series of genes with complex molecular regulations that favor xylem diff erentiation into a root primordium (Pereira and Bandeira, 2016). It was found that there was no correlation between cuttings rooting and callus formation, indicating that the adventitious root formation in Azadirachta indica cuttings occurs directly.…”

Finding forest species adapted to diff erent soil and climatic conditions and, that provide favorable attributes to commercial use is a challenge. Azadirachta indica is a potential species to attend to this goal. Thus, this paper aims to carry out the vegetative rescue of diff erent Azadirachta indica Juss adult trees by cuttings. For that, Azadirachta indica individuals were randomly selected in a plantation of species set ten years ago and the cut was carried out at 30 cm in height. In sequence, verifi cation was carried out on: (a) the stem cut ability to regrowth (collections and measurements of the shoot length on the 15 th , 30 th , 45 th , and 60 th days); (b) the need to use exogenous auxin for rooting induction [testing 0 (control), 2000, 4000, and 6000 mg.l -1 of Indole-3-butyric acid (IBA)]; (c) the ideal of the propagule size (with 8 cm and 13 cm in height); and (c) the rooting dynamics (every seven days for thirty-fi ve days; the propagules were evaluated for callus formation, oxidation, and rooting). The species showed high regrowth ability, as well as easy rooting with or without the use of IBA; it was found that the ideal size for the propagule is 13 cm and that the process of rooting and root elongation is completed after thirty-fi ve days of staking. The conclusion is: (a) using cuttings for the species vegetative rescue is interesting; (b) 13 cm is considered appropriate for the propagule size, and; (c) the aid of IBA at a dose of 2,000 mg L -1 is ideal to standardize rooting.

“…The nutritional condition of the collected propagule determines the amount of metabolic compounds, such as carbohydrates and auxins, which are essential to the rhizogenesis initiation and speed (Xavier et al, 2013;Pereira and Peres, 2016;Almeida et al, 2017). According to Dias et al (2012), the more nourished the plant, the greater the number of cells produced by the meristems and the longer the growth axis will be, thus reaching the lower end of the tube in a short time.…”

“…Outras características a serem consideradas e que são de extrema importância para o êxito na produção de mudas via propagação vegetativa é a idade, o estado fitossanitário e nutricional da planta matriz quando esta é doadora de material usado na propagação. Esses fatores, principalmente o estádio nutricional, podem determinar a quantidade de carboidratos, auxinas e outros compostos do metabolismo essencial da planta para a iniciação e desenvolvimento das raízes adventícias (Pereira & Peres, 2016). Sendo assim, é pertinente destacar que estacas com maiores reservas de carboidratos podem apresentar melhores taxas de enraizamento.…”

A nutrição mineral é fator determinante no enraizamento adventício, com envolvimento nas respostas morfogenéticas, processos bioquímicos e fisiológicos. A inﬂuência dos minerais sobre o sucesso do enraizamento apresenta correlação com o estado nutricional da planta matriz doadora, pois esta determina a quantidade de carboidratos, hormônios e outros compostos metabólicos essenciais para induzir o desenvolvimento radicular e vegetativo. Embora o enraizamento e a nutrição mineral estejam intimamente relacionados, poucos estudos têm sido divulgados visando à caracterização dos efeitos de nutrientes específicos. Neste contexto, realizou-se, com base em informações disponíveis na literatura, uma análise do papel de alguns nutrientes envolvidos na rizogênese adventícia de espécies cultivadas via propagação vegetativa. Com isso, é pertinente considerar que se o nutriente estiver envolvido nos processos metabólicos da planta e possibilitar a desdiferenciação para formação do meristema radicular, este é essencial para rizogênese. Dessa forma, infere-se que o nitrogênio, fósforo, zinco e boro são elementos necessários para algumas espécies durante o processo de propagação vegetativa por participarem diretamente do processo de enraizamento.
