“…Therefore, the presence of structures that are responsible for the synthesis and release of scent in their floral organs is expected. The vast majority of studies refer to such scent glands as epithelial osmophores (Vogel, ; Endress, ; Marinho et al ., ), with rare reports of trichomes acting in the long‐distance attraction of pollinators (see Vogel, ; Stpiczyńska, ; Guimarães, Di Stasi & Maimoni‐Rodella, ; Wiemer et al ., ; Naidoo et al ., ; Chwil et al ., ; Nadia, Menezes & Machado, ; Marinho et al ., ; Marques et al ., ; Pansarin & Pansarin, ; Boff et al ., ).…”

The uncommon cavitated secretory trichomes inBauhinia s.s.(Fabaceae): the same roles in different organs

2015

Cavitated secretory trichomes are characterized by a short or absent stalk that is connected to a secretory hollow head. They are rare structures in angiosperms; in Fabaceae, they have been recorded in only seven genera, including Bauhinia s.s. Because B. curvula and B. rufa exhibit glands that are responsible for attracting pollinators to flowers, this study aimed to test whether the cavitated secretory trichomes present in the flowers of these species have an attraction function. As leaf trichomes are commonly related to plant defence, comparative analyses of the morphology, ontogeny, ultrastructure and chemical profile of the secretory trichomes present in flowers and leaves were conducted. It was found that cavitated secretory trichomes are similar in their external morphology and development, regardless of the organ or species analysed. However, interspecific differences were found in the secretion process and chemical profile of the exudate. The differences found in the cavitated secretory trichomes between species indicate that they secrete distinct compounds, whereas the similarities found in these structures between vegetative and reproductive organs indicate that the cavitated trichomes have equivalent ecological functions within a species, probably in plant defence during organ development. © 2015 The Linnean Society of London, Botanical Journal of the Linnean Society, 2016, 180, 104–122.

“…The genus Angelonia originates in the Neotropical region, which covers the area from central Mexico to the southern tip of South America (BOFF et al, 2014). The emergence of different species is not yet fully understood (PLASCHIL and OLBRICHT, 2008;GOSCH et al, 2014), with report of approximately 50 species (TROPICOS, 2018), and differences related to the shape and color of the flower, ranging between blue, violet, white and pink (GOSCH et al, 2014).…”

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.

Resumo Devido à dificuldade de obtenção de mudas de Agelonia integerrima, espécie com potencial ornamental, a partir de sementes, por métodos convencionais, foram desenvolvidos estudos com o objetivo de testar a viabilidade da produção de mudas in vitro. Foram conduzidos quatro experimentos: a) germinação de sementes armazenadas em dois locais (ambiente refrigerado e bancada de laboratório) e concentrações de sais (100, 75 e 50%) do meio MS; b) multiplicação com benzilaminopurina (BAP) (0,0, 0,5 e 1,0 mg L-1) e ácido naftalenoacético (ANA) (0,0, 0,1 e 0,5 mg L-1); c) enraizamento in vitro com ácido indolbutírico (AIB) (0; 0,25; 0,50; 0,75 e 1,0 mg L-1); d) aclimatização das mudas. Sementes armazenadas sob ambiente refrigerado apresentaram maior porcentagem de germinação, índice de velocidade de germinação e de plântulas formadas. A germinação não foi afetada pela concentração de sais do meio. Para a multiplicação, houve interação entre as concentrações de BAP e ANA, recomendando-se utilizar 1,0 mg L-1 de BAP e 0,1 mg L-1 de ANA. No enraizamento, foi ajustada uma equação quadrática para as variáveis: porcentagem de formação de calo e enraizamento, sendo que a concentração de 0,83 mg L-1 é o ponto de máxima resposta para a porcentagem de enraizamento. A espécie apresentou 50,8% de aclimatização.
