“…Similar to this study, the low germination or emergence percentage promoted by the control (presenting sarcotesta) was also observed in other species; such as, Eugenia jambolana, 18% (Araújo et al, 2015); Carica papaya, 24% (Melo & Seleguini, 2013); and P. alata, 6% (Osipi et al, 2011). This may indicate that the substances compounding the sarcotesta or aryl inhibit the seed germination.…”

“…However, studies on other species have shown positive results (Martins et al, 2006;Osipi et al, 2011;Aguiar et al, 2014;Araújo et al, 2015). Similarly, Silva (2012) relates that this method promotes a chemical seed scarification causing the breakage and abrasion of the sarcotesta, which increase the water permeability and germination, as seen in this study.…”

“…This may indicate that the substances compounding the sarcotesta or aryl inhibit the seed germination. Several studies can confirm those substances in some species, including Talisia esculenta (Alves et al, 2009); P. edulis (Martins et al, 2010); P. alata (Osipi et al, 2011); C. papaya (Melo & Seleguini, 2013); and E. jambolana (Araújo et al, 2015). Martins et al (2010) using extract from P. edulis aryl associated to dichloromethane and tween, obtained a reduction in the Lactuca sativa germination and high percentage of dormant seeds, presenting similar means to those noticed in here when the sarcotesta was not removed from the seeds ( Table 1).…”

“…Others treatments as quicklime (CaO), can also be used to eliminate the mucilage from fleshy fruits (Silva, 2012). This technique has been investigated by several authors in different species (Martins et al, 2006;Freitas et al, 2011;Osipi et al, 2011;Aguiar et al, 2014;Santos-Moura et al, 2014;Araújo et al, 2015); but, at the same time, its effect on pomegranate seeds still unknown. during the storage (Carvalho & Nakagawa, 2012).…”

Aiming to evaluate the effect of degumming methods and natural drying, as well as, the influence of different periods of seeds in quicklime solution on Punica granatum L. germination, were conducted two experiments. At first, the seeds from ripe fruits were subjected to the following sarcotesta extraction: natural fermentation at room temperature, during 72 hours; immersion in quicklime (CaO), during 24 hours; and non-degumming, taken as control. For the second experiment, the extraction method was carried out by the following mixture: seeds, quicklime, and distilled water; differing the immersion period (5, 10, 15, 20, and 25 hours). In both, the experimental design was completely randomized, performing the water content and germination test. The quicklime method is efficient to degrade and to eliminate the sarcotesta on P. granatum seeds, and the drying process provides a better germination. In addition, there is a linear increase on seed physiological quality when upgrades the immersion period in quicklime solution.

“…In other studies, seed immersion in quicklime solution for 10 minutes was evaluated for Passilora edulis (MARTINS et al, 2006) and Passilora alata (OSIPI et al, 2011). For Eugenia jambolana, the seeds were mixed with quicklime inside a container for 10 minutes, which produced friction, and then washed (ARAÚJO et al, 2015).…”

Sarcotesta removal methods and GA3 treatment on germination of Punica granatum L. seeds

et al. 2018

View full text Add to dashboard Cite

A propagação em Punica granatum é realizada, predominantemente, através da semente, ocorrendo baixa taxa de germinação, devido à dormência e à rápida perda do seu poder germinativo. Investigações relacionadas à remoção da sarcotesta em sementes dessa espécie são escassas, como também a utilização de tratamentos pré-germinativos de ácido giberélico (GA3). Com isso, objetivou-se avaliar o efeito de métodos de remoção do arilo e o tratamento com GA3, na germinação de sementes de P. granatum. As sementes foram extraídas de frutos maduros e submetidas a três métodos para extração da sarcotesta: 1) lavagem manual em peneira e água corrente; 2) repouso em solução de cal virgem, durante 24 h; e 3) fermentação em sacarose, por 72 h. As sementes foram divididas em duas porções iguais, uma imersa em solução de 200 mg L-1 de GA3 e outra sem imersão em GA3. A degomagem com cal virgem foi eficiente, removendo de modo fácil e rápido toda sarcotesta das sementes, proporcionando maior velocidade (4,26) e percentual (60%) de germinação às mesmas. O tratamento com cal virgem associado à aplicação de GA3 promoveu um incremento no percentual de germinação (70%), contribuindo para melhor superação da dormência.

-Yellow passion fruit has conquered a significant position in the agribusiness of tropical fruits; therefore, farmers have been interested in expanding their groves, and technical information that guarantees the high yield of the farmings is needed. Aiming to observe factors related to the propagative material targeted at quality and maximization of the genetic potential, the objective of the study consisted in assessing germination and emergence of passion fruit seeds collected in three positions in the fruits and submitted to different methods of mucilage removal (aryl). The passion fruits were split in three parts: distal, medial and proximal and the contents of each part was divided in two. The content of each part of the fruit was submitted to mechanical and by fermentation methods for removal of aryl. It is concluded that the seed position in the fruit does not interferes with the germination. The aryl removal method by mechanical extraction affects the germination and seedling emergence.Index terms: Passiflora edulis, mechanical extraction, fermentation, propagation, mucilage. Métodos de remoção do arilo e posições das sementes no fruto de maracujá:Germinação e emergência RESUMO -O maracujá-amarelo conquistou significativa posição no agronegócio de frutas tropicais, com isso, produtores despertaram interesse para expandir seus pomares, sendo necessárias informações técnicas que garantam a alta produtividade das lavouras. No intuito de observar fatores relacionados ao material propagativo visando a qualidade e a maximização do potencial genético objetivou-se avaliar a germinação e a emergência de sementes de maracujá coletadas em três posições nos frutos e submetidas a métodos de retirada da mucilagem (arilo). Os frutos de maracujá foram seccionados em três partes: distal, mediana e proximal. Cada um destes conteúdos foi submetido aos métodos mecânico e de fermentação para remoção do arilo. Podendo concluir que a posição da semente no fruto do maracujazeiro não interfere na germinação e o método de remoção do arilo por extração mecânica prejudica a germinação e a emergência de plântulas.Termos para indexação: Passiflora edulis, extração mecânica, fermentação, propagação, mucilagem.
