Utilização De Métodos Físicos E De Fitorreguladores Para Superação De Dormência Em Sementes De Pinha

Abstract: A pinha é uma fruta muito apreciada devido ao sabor, e pode ser propagada por sementes ou de forma vegetativa por enxertia. No entanto, a produção de mudas por propagação seminal é dificultada pela dormência acentuada das sementes. Neste aspecto, objetivou-se determinar o melhor tratamento para a superação de dormência de sementes de pinha (Annona squamosa L.), submetendo-as à associação de tratamento pré-germinativo mecânico e não mecânico. Foi empregado o delineamento experimental inteiramente casualizado em… Show more

“…Research by Vasconcelos et al (2015) determined that the effect of gibberellic acid application on seedling emergence were dependent on the use of higher concentrations, which provided increments in germination percentage, emergence speed index and averagetime for seed germination in relation to absence of gibberellic acid. The trait root dry mass (Figure 1b) adjusted to the quadratic polynomial model: Ŷ = 0.0723 + 0.0006x -3E-06x 2 , revealing coefficient of determination of R 2 : 0.76, being possible to increment this trait through the The lowest magnitude of this trait is related to modificationsin the relation of plant drains during seed production period, which is related to growth, dry matter of seed and total in the plant (Benincasa, 2003).…”

“…Assim, a partir do aumento dessa variável com a aplicação isolada do GA 3 , na ordem de 8,14%, em relação à aplicação do bioestimulante (Tabela 1), presume-se que a aplicação isolada de GA 3 aumente o vigor das sementes. Outros estudos têm demonstrado que o tratamento pré-germinativo com GA 3 proporciona maior velocidade de germinação de várias espécies (SANTOS et al, 2013;CAMPOS et al, 2015;VASCONCELOS et al, 2015). Este efeito está ligado à elongação e divisão celular proporcionado pelo fitormônio (TAIZ; ZEIGER, 2013).…”

“…For species of the Anonaceae family, such as Rollinia mucosa (Jacq.) Baill (Campos et al, 2015) and Annona squamosa L. (Vasconcelos et al, 2015), mechanical scarification accompanied by the application of gibberellic acid significantly increases seed germination. Mechanical scarification was also effective for increasing the emergence of Euterpe oleracea (Mart.)…”
