“…), under conditions of intermittent misting, in a riparian chamber with 50% shading, in the municipality of Mossoró-RN, Brazil, and obtained a percentage of 30% of sprouted cuttings. The above mentioned behavior was also observed by Yamamoto et al (2013) in "Xavante" mulberry, who observed that the sprouted cuttings percentage did not show any statistical difference with application of indolebutyric acid treatments.…”

Umbuzeiro (Spondias tuberosa Arr. Cam.) is a plant native to Brazilian semi-arid regions. Currently, there is no protocol for propagation for this species. In this sense, the aim of this study was to evaluate the propagation of Umbuzeiro by cuttings, using ethephon and indolebutyric acid (IBA). In this study, a completely randomized statistical design was used with the doses of ethephon (0, 14.5, 50, 85.5, 100 mg L -1 ) and IBA (0, 872.35, 3000, 5127.65, 6000 mg L -1 ) combined by the matrix "Central Compound Box" in 4 replicates. After application of ethephon and IBA on plants, cuttings with 20 cm length were prepared and planted in tubes with sand and organic compound (1:1 v/v) and placed in a greenhouse at 50% light under misting. The percentage of sprouted cuttings, length and diameter of the shoots, the percentage of rooted cuttings, live cuttings with and without calyx, dead cuttings, number of roots and length, dry matter of roots, leaf and total dry matter were evaluated. A combination of the doses of 100 mg L -1 of ethephon and 6000 mg L -1 of IBA increased the percentage of sprouted cuttings, number of shoots per cutting, number of roots per cuttings and promoted the rooting of 47.20% of the Umbuzeiro cuttings. The shoot formation and dry matter of Umbuzeiro cuttings were not influenced by the doses of ethephon. The IBA doses increased shoot formation and dry matter production of the umbuzeiro cuttings under greenhouse conditions.

“…Among these substrates, there are a lot of commercial mixtures based on composted pine bark, vermiculite, peat and other materials. On the other hand, some materials considerate as residues in agricultural exploration can be employed to plant propagation, such as coconut fiber, carbonized rice husk and tree bark (Yamamoto et al, 2010(Yamamoto et al, , 2013Hussain et al, 2014). These materials present lower cost and are ecological, which implies in cost reduction in the nurseries production.…”

The nursery plants supply is one of the most important factors that limites blueberries production in some areas, due to some propagation difficulties observed on this species. In this way, this study aimed to evaluate substrates and IBA application methods on 'Powderblue' blueberries (Vaccinium ashei) minicuttings rooting, as well as to verify the rooting development in different periods. The study was divided in two experiments. The first one aimed to evaluate 'Powderblue' blueberry minicuttings rooting in three substrates (pine bark, carbonized rice husk and vermiculite) in response to two indolebutyric acid (IBA) application methods: 50% alcohol solution and talc. The second experiment aimed to evaluate 'Powderblue' blueberry minicuttings rooting using the best substrate recorded in the first trial (pine bark) and two IBA application methods associated to three periods of rooting access, in order to obtain the ideal rooting period and root development. In the first experiment the rooting percentage presented significant difference among the substrates; the higher percentage of rooted minicuttings occurred in pine bark substrate (68%). Regarding the methods used to IBA application, the talc method was more efficient to promote minicuttings rooting. In the second experiment, it was observed an increase in cutting rooting percentage from 55 to 84%, according to the evaluated seasons; however, the IBA application method did not influence the rooting percentage. Therefore, to produce 'Powderblue' blueberry plants from minicuttings it is recommended to use pine bark as substrate and talc as method to IBA application, transplanting the nurseries at 110 days after planting.

“…In the production of seedlings by cutting, the choice of a suitable substrate is of fundamental importance. It must provide enough water to avoid cutting dewatering, and facilitate the supply of oxygen, with adequate pore space, to begin the process of root formation (YAMAMOTO et al, 2013).…”

The objective of this study was to evaluate the effect of the concentration of indole-3-butyric acid (IBA) and substrates in the rooting of apical cuttings of Angelonia integerrima. Powder IBA was used at the concentrations 0, 500, 1,000, 2,000 and 4,000 mg kg -1 , and two substrates containing carbonized rice husks (CRH) and commercial substrate based on Sphagnum peat were used. The number of rooted cuttings, shoot length, root system length, number of new leaves, root system volume, callus formation at the cutting base, and shoot and root dry matter were evaluated. The experimental design was completely randomized with a factorial design (5 IBA concentrations x 2 substrates). There were no interactions between the concentrations of IBA and the substrates. There was a difference only for the factor substrate. The cuttings presented an average rooting of 79%, with callus formation in 59.4% of them. The CRH substrate presented the highest shoot length and the highest number of new leaves. The commercial substrate resulted in a high average root volume, a large root length and a great increase in root dry matter. In the rooting by cutting of A. integerrima is not necessary to use IBA and the commercial substratum based on peat or CRH can be used. Keywords: vegetative propagation, floriculture, native ornamental specie. RESUMO Enraizamento de estaca apicais de Angelonia integerrina Sprengel: concentrações de ácido indol-3-butírico e substratosO objetivo do trabalho foi avaliar o efeito da concentração de ácido indol-3-butírico (AIB) e substratos no enraizamento de estacas apicais de Angelonia integerrima. Utilizou-se AIB em pó, nas concentrações de 0, 500, 1000, 2000 e 4000 mg kg -1 e dois substratos: casca de arroz carbonizada (CAC) e substrato comercial a base de turfa de Sphagnum. Avaliou-se: número de estacas enraizadas, comprimento da parte aérea e do sistema radicular, número de folhas novas, volume do sistema radicular, formação de calo na base da estaca, massa seca da parte aérea e do sistema radicular. O delineamento experimental foi inteiramente casualizado, em esquema fatorial (5 concentrações de AIB x 2 substratos). Não houve interação entre as concentrações de AIB e substratos, somente houve diferença para o fator substrato. As estacas apresentaram enraizamento médio de 79%, com formação de calo em 59,4%. O substrato CAC promoveu maior comprimento da parte aérea e maior número de folhas novas. O substrato comercial proporcionou maior volume médio de raiz, maior comprimento de raiz e maior incremento de massa seca radicular. No enraizamento por estaquia de A. integerrima não é necessário usar AIB e pode-se utilizar o substrato comercial à base de turfa ou a CAC. Palavras-chave: propagação vegetativa, floricultura, espécie ornamental nativa.
