“…Once de-pulped, four hundred seeds were used, being two hundred from mature fruits and two hundred green fruits, were washed in running water and subsequently subjected to a dormancy breaking test following the methodology of Vasconcelos et al (2010). Briefly, the seeds were soaked in distilled water for 48 h at room temperature (25±3°C); disinfected in a laminar flow cabinet, with the seeds remaining for one minute in 70% alcohol and four minutes agitated in commercial 100% sodium hypochlorite (Qboa, Industries Anhembi, Curitiba-PR, Brasil); and then rinsed three times with distilled and autoclaved water.…”

“…For M. elliptica Mart., gibberellic acid, sulfuric acid and water immersion, cooling and heating and mechanical scarification were studied by Vasconcelos et al (2010), who achieved success with pre-soaking in gibberellic acid, soaking in water for 48 h and mechanical scarification of seeds. However, increased soaking times, which is a simple and inexpensive method, were not evaluated; thus, the study presented here is essential, and the results verified that an increase in soaking time of non-scarified seeds for up to six days has an impact on seedling emergence in this species, which exhibits tegumentary dormancy.…”

“…Interest in the conservation of native Cerrado species prompted the study by Vasconcelos et al (2010) on the dormancy and breaking of dormancy in M. elliptica Mart. seeds, which was the first such report and verified that soaking seeds in distilled water for up to 48 h and mechanical scarification increased germination rates compared with seeds that did not receive such treatment.…”

“…For the genus Mouriri, only any studies have been conducted on its germination and chemical composition (Salis and Mattos, 2010;Vasconcelos et al, 2010;Rufino et al, 2011;Silveira et al, 2013), and there is a lack of research related to in vitro propagation in this genus (comment author). Therefore, the aim of this study was to evaluate the influence of the fruit ripening stage as well as the influence of seed scarification and soaking on the germination of seeds in vitro and in a greenhouse.…”

This study is aimed to describe the germination process of Mouriri elliptica Martius, a species in the Melastomataceae family that is native to the Cerrado (tropical savannah) and popularly known in Portuguese as croada, coroa de frade [friar's crown], croadinha [little croada], puçá-preto [black net], or jabuticaba-do-Cerrado. The species has significant potential for use as food and medicine; however, there is a dearth of scientific studies on this plant. Two experimental tests were performed to clarify the germination process of this species: Germination was evaluated in vitro by integrating fruit ripening and culture medium, and the emergence and initial growth of M. elliptica Mart. seedlings obtained from seeds soaked for different lengths of time were observed in a greenhouse. It was verified that the in vitro environment was not effective for germination independent of the culture medium, even using known and effective methodologies for breaking dormancy in seeds of this species. For the emergence of seedlings, it was found that soaking seeds in distilled water for two days was the optimal length of time for seedling production.

“…Para a produção de mudas de canafístula, é necessária a quebra da dormência natural de suas sementes, ocasionada pela impermeabilidade de seu tegumento. A dormência tegumentar é muito frequente entre as espécies florestais, caracterizando-se pela dificuldade de absorção de água pela semente, o que a impede de iniciar a hidratação e, consequentemente, restringe as reações metabólicas bási-cas da germinação (Azeredo et al, 2010;Vasconcelos et al, 2010). Entre os tratamentos de quebra de dormência utilizados, com sucesso, para superação da dormência tegumentar de espécies florestais, destacam-se as escarificações mecânica e química, além da imersão das sementes em água quente (Oliveira et al, 2003).…”

This study aimed to evaluate the effect of different methods to break dormancy and the use of sugarcane bagasse in the composition of alternative substrates made from a mixture of commercial substrate, in canafistula (Peltophorum dubium (Sprengel) Taubert) seedling production The experiment was carried out in randomized blocks in a 4 x 5factorial design, with five substrates, Bioplant ® ; 75% Bioplant ® + 25% sugarcane bagasse (75B+25BC); 50% Bioplant ® + 50% sugarcane bagasse (50B+50BC); 25% Bioplant ® + 75% sugarcane bagasse (25B+75BC), sugar cane bagasse (100%) and four methods of breaking dormancy (control, scarification with sandpaper, immersion in hot water and scarification with sulfuric acid) with three replications. The emergence index (IVE), mean emergence time (TME), emergence percentage, Substratos alternativos e métodos de quebra de dormência para produção de mudas de canafístula O objetivo deste estudo foi avaliar o efeito de diferentes métodos de quebra de dormência e o uso do bagaço de cana para composição de substratos alternativos, constituídos a partir da mistura de um substrato comercial, na produção de mudas de canafístula (Peltophorum dubium (Sprengel) Taubert). O experimento foi conduzido em delineamento de blocos casualizados, no esquema fatorial 5 x 4, sendo cinco substratos, Bioplant ® ; 75% Bioplant ® + 25% Bagaço de cana (75B+25BC); 50% Bioplant ® + 50% Bagaço de cana (50B+50BC); 25% Bioplant ® + 75% Bagaço de cana (25B+75BC); Bagaço de cana (100%), e quatro métodos de quebra de dormência (testemunha, escarificação com o uso de lixa, imersão em água quente e escarificação com ácido sulfúrico) com três repetições. Foram avaliados o índice de velocidade de emergência (IVE); o tempo médio de emergência (TME); a percentagem de germinação; a altura da parte aérea; o diâmetro do coleto; a massa seca da parte aérea; a massa seca de raiz; a massa seca total; a relação altura da parte aérea/diâmetro do coleto; a relação altura da parte aérea/massa seca da parte aérea; o índice de qualidade de Dickson; a taxa de crescimento absoluto e a taxa de crescimento relativo. Os tratamentos de imersão em água quente e de escarificação com ácido sulfúrico foram responsáveis pelos maiores percentuais de emergência e IVE, além dos de menor TME. O uso do bagaço de cana mostrou-se tecnicamente viável na composição dos substratos 75B+25BC e 50B+50BC, que, juntamente ao Bioplant ® , proporcionaram as maiores taxas de crescimento e os maiores índices de qualidade das mudas de canafístula. Palavras-chave:Peltophorum dubium ((Sprengel) Taubert), sementes florestais, Bioplant ® , bagaço de cana, viveiro.
