“…Moreover, the application of IBA improved adventitious rooting. A number of studies have shown increased adventitious rooting with IBA, such as in Bixa orellana (MANTOVANI et al, 2010), Syzygium jambos (MARTINS; ANTUNES, 2000), Vitis rotundifoliae (PACHECO et al, 1998) and Prunus persica SILVEIRA, 2003). Our data also showed that IBA (3.0 or 8 g .…”

Swietenia macrophylla yields high-quality wood; however, its vulnerability to extinction coupled with challenges for its cultivation have brought attention to its replacement for alternative species such as the Khaya anthotheca. The species has been recently introduced to South America, with potential for the production of high-quality wood. However, limited background on breeding and efficient strategies for its vegetative propagation exist. Here, we achieved significant results with the application of cleft grafting and air layering for the propagation of K. anthotheca plants grown from seeds. First, we analyzed the compatibility of scions and rootstocks for intraspecific and interspecific cleft grafting combinations of K. anthotheca and S. macrophylla. Second, air layering was performed in K. anthotheca seedlings irrigated with three nutrient solution (100%, 50% and 25% of the initial concentration of nutrients) combined with the application of indole-3-butyric acid (IBA) to evaluate adventitious rooting. From cleft grafting, we achieved an overall graft compatibility and survival of 48% after 200 days. However, the interspecific combination of S. macrophylla (scion) and K. anthotheca (rootstock) implicated in no compatibility, while the reciprocal resulted in 52% of compatibility. Through air layering, the irrigation with the nutrient solution with at least 50% of the nutrients concentration and with IBA (3.0 or 8.0 g.L-1) resulted in the best adventitious rooting. Overall, we recommend cleft grafting, except for the combination S. macrophylla (scion) and K. anthotheca (rootstock), with no compatibility. Air layering might also be useful for the propagation of K. anthotheca genotypes in breeding programs.

“…Esses resultados corroboram com Farias Júnior et al (2015), que constataram o início do enraizamento mais rápido em faveleira com uso de indutor de enraizamento. Lucena et al (2014) constataram que mesmo com o uso de AIB na mesma concentração (6,0 g L -1 ), o aparecimento de raízes iniciou mais tarde, aos 42 dias após a realização dos alporques em matrizes de Cnidoscolus quercifolius, porém, utilizando vermiculita como substrato e em um período de avaliação com menor pluviosidade. Em condições semelhantes aos autores citados, Campos et al (2015) relataram que as primeiras raízes apareceram na superfície dos substratos aos 42 dias após a realização das alporquias utilizando os substratos vermiculita e orgânico comercial Plantmax®.…”

Cnidoscolus quercifolius Pohl (faveleira) é espécie arbórea nativa do bioma Caatinga, amplamente utilizada pelas populações locais inseridas neste bioma, no tratamento de processos inflamatórios. Esta pesquisa teve por objetivo avaliar a ausência e presença de ácido indol butírico (6,0 g L-1 de AIB) e seis substratos, compostos de fibra da casca de coco verde (FC), pó da casca de coco verde (PC) e rejeito de vermiculita (RV) na produção de mudas de faveleira pela técnica clonal de alporquia. Observações semanais na superfície do substrato foram realizadas para detectar o surgimento de raízes no alporque, até 90 dias. Os ramos com os alporques foram removidos e coletados os seguintes dados: alporques sem calos; alporques com calos (formação de massa celular indiferenciada na região do anelamento); alporques com primórdios radiculares e alporques enraizados. Nos alporques enraizados, analisou-se o número de raízes, comprimento da maior raiz (cm) e massa seca das raízes (g). Por meio da contagem dos alporques enraizados foi calculada a porcentagem de enraizamento dos alporques. O uso do AIB foi eficiente no incremento do comprimento, número e massa seca de raízes. O substrato com 1/3 de fibra da casca de coco verde + 1/3 de pó da casca de coco verde + 1/3 de rejeito de vermiculita é o mais eficiente para o enraizamento de alporques em ramos de faveleira e de baixo custo.

“…On the other hand, this technique presents Tamwing et al (2020) Concentrations of indolebutyric acid on... limitations due to its slow and challenging execution, resulting in low seedling yield. Air-layering has been studied in the propagation of several fruit species, such as umbu (Spondias tuberosa) (Dutra et al, 2012), black plum ((Syzygium cumini (L.) Skeels) (Silva et al, 2019), jaboticaba (Plinia cauliflora) (Sasso et al, 2010;Cassol et al, 2015), and achiote (Bixa orellana) (Mantovani et al, 2010).…”

Concentrations of indolebutyric acid on air-layering of guava cv. Paluma

et al. 2020

Nowadays, the predominant technique for the commercial propagation of guava seedlings is through cuttings, using herbaceous cuttings that need a specialized infrastructure with intermittent misting, clean water, exhausters, water filters, and fans. As an alternative to plant propagation by cuttings, this study aimed to evaluate the influence of concentrations of indolebutyric acid (IBA) on the rooting of branches of the guava cv. Paluma by air-layering. The experimental design was in randomized blocks, with four replications and 10 air layers per plot. The treatments consisted of six concentrations of IBA powder mixed with industrial talcum: 0, 1,000, 2,000, 3,000, 4,000, and 5,000 mg.kg-1. Four adult guava parents that were in the off-season period were used. For the preparation of the air layers, the stems were girdled with a 4.0 cm width, using a steel blade, by removing the bark until exposing the cambium region, followed by IBA application and wrapping of the branches with a plastic bag containing moist organic substrate. The following variables were evaluated 120 days after air-layering: percentage of rooted and callused air layers, longest root length, and root dry matter. The analysis of variance indicated no significant differences between the IBA concentrations for all variables, but the rooting percentages were high (68.6 to 92.2%) regardless of the application of the exogenous auxin.
