“…The images showed that the black color was predominant, occurring in 80% of the seeds, but smaller amounts of blue (7%), sky blue (7%), and dark gray (6%) were also present (Figure 1). Although the seeds of Strelitzia reginae (Pirone et al, 2010;Paiva et al, 2012), Strelitzia nicolai (Duretto et al, 2017), and Phenakospermum guyannense (Oliveira et al;2012) were described as only black in color, the analysis performed indicated the existence of other colors, such as blue and gray. Notably, in vitro oxidation compounds on a medium culture during in vitro cultivation were identified, and different colors were present in the exudates, including blue (Paiva et al, 2000).…”

“…Contour irregularity was determined in the Strelitzia reginae seeds, with an average of 0.07, and the seed perimeter and convex perimeter were 2.42 and 2.09 cm, respectively (Table 1). (Oliveira et al;2012) and some have described the morphological aspects of the seeds of the genus Strelitzia (Duretto et al, 2017), there is no characterization of the complete morphometric analysis of Strelitzia reginae seeds.…”

“…Strelitzia reginae Banks ex Aiton is also popularly known as the bird-of-paradise, queen-of-paradise, toucan's beak, flower-of-paradise, queen flower or garden banana (Vieira, 2012). Strelitzia has great commercial value, with attractive colorful inflorescences, and is widely used for both the production of cut flowers and seedlings for gardens (Paiva et al, 2012;Vieira et al, 2014).…”

Strelitzia or bird-of-paradise, is an important tropical ornamental plant that is difficult to propagate because of seed dormancy issues and the low number of seedlings obtained from plant divisions. With greater knowledge of its structure, it is possible to develop strategies to improve the propagation process for this species, since information on this subject is currently limited. Thus, the objective was to carry out an anatomical, morphological and biochemical characterization of Strelitzia reginae seeds and embryos. The characterization of the seeds was performed through image analysis using GroundEye equipment, X-rays, and anatomical and biochemical analyses. Additionally, the following biometric characteristics of the seeds were obtained: an area of 0.33 cm2, a maximum diameter of 0.736 cm, a maximum lateral diameter of 0.59 cm, a minimum diameter of 0.58 cm, and a perimeter of 2.47 cm. The seeds of S. reginae can be considered starchy since they contain 15% starch. By integument anatomical analysis, we observed the presence of an exotesta (ex) and a posterior parenchymatic layer that was divided into a mesotest (m) and endotest (en). The characterization of Strelitzia reginae seeds and embryos showed relevant observations for the taxonomy and physiology of this species. The seeds are aleurostarches and present an area of 0.33 cm2 on average, with maximum lateral diameter of 0.59 cm. As result of anatomical studies, it was possible to determine coat responsible for integument dormancy.

Strelitzia reginae is used in some African countries as a traditional medicine with very few phytochemical and biological assessments. The study aims to isolate and structure elucidate of S. reginae phytoconstituents using different chromatographic and spectral techniques. In addition to, antimicrobial assessment of ethyl acetate and n-butanol fractions on both clinical isolates and standard strains. Strelitzia reginae belongs to the family Strelitziaceae which is a rich source of biologically active phytoconstituents and has diverse therapeutic values. Strelitzia reginae leaves were fractionated into ethyl acetate and n-butanol, and five compounds were detected. Compounds were identified as kaempferol (1), quercetin (2), daucosterol (3), vitexin (4), and rutin (5). The isolated compounds were elucidated by their NMR and ESI-MS spectral data. Antimicrobial activity of Strelitzia reginae ethyl acetate and n-butanol fractions screened against six different bacterial strains (three Gram-positive, three Gram-negative, and one fungus isolate). Both fractions showed antimicrobial activities against Klebsiella pneumonia and Staphylococcus aureus which is methicillinresistant (MRSA) strains. As well, the activity of antimicrobial was detected against Proteus mirabilis clinical isolate from urine and MRSA. On the other hand, both fractions showed inadequate antimicrobial activities against the Pseudomonas aeruginosa, Staphylococcus aureus and Candida albicans clinical isolates compared to reference drugs. The antimicrobial results were in accordance with previously reported folk uses and attributed to the isolated phytoconstituents.

“…No comércio de ornamentais existe uma procura muito grande por folhagens e complementos para atender o setor de flores cortadas (NEVES; PINTO, 2015). A Strelitzia, popularmente conhecida como ''ave-do-paraíso'' (VIEIRA et al, 2012), é uma planta herbácea, perene, originária da África do Sul, de 1,2 a 1,5 m de altura, de florescimento decorativo, com folhas firmes e coriáceas (LORENZI; SOUZA, 2008). Sua comercialização como planta de corte é advinda à grande durabilidade pós-colheita de suas plantas (PIVETTA; BARBOSA; ARAÚJO, 2007).…”

A floricultura constitui um dos segmentos mais dinâmicos do agronegócio e a utilização de arranjos florais exige alto padrão de qualidade de seus produtos e uma maior longevidade pós-colheita das flores. A quitosana é um polissacarídeo biodegradável capaz de formar um filme natural e permeável às trocas gasosas realizadas pelo vegetal, permitindo a redução do metabolismo da planta favorecendo o prolongamento de sua vida útil. Este estudo teve como objetivo avaliar a durabilidade pós-colheita de folhas de Strelitizia reginae e Strelitizia juncea utilizando produto comercial a base de quitosana (FishFertil®). O experimento foi conduzido inteiramente casualisado de 6 tratamentos com 5 repetições (onde cada folha foi considerada como uma repetição). Foram utilizadas 6 doses ( 0 ; 10 ; 20 ; 40 ; 80 e 160 mg L-1 do produto comercial). Realizaram-se avaliações visuais da longevidade das folhas através de notas e o acompanhamento da perda de água nos tecidos foliares. Observou-se que FishFertil® retardou a perda de massa fresca das folhas de S. juncea e S. reginae. Para ambas as espécies o tratamento controle permaneceu até o 22° dia com notas aceitáveis comercialmente (nota 4). O produto retardou a perda de massa fresca das folhas de S. juncea e S. reginae e as mantiveram até o 34° dia notas dentro do padrão comercial, contudo não foi possível determinar a dose de máxima eficiência do produto para as duas espécies de Strelitzia.
