Efeito da temperatura na avaliação da qualidade fisiológica de sementes do maracujá-doce (Passiflora alata Dryander)

Abstract: RESUMO -Com o objetivo de verificar condições favoráveis de temperatura para a germinação das sementes do maracujá-doce (Passiflora alata Dryander), utilizou-se como tratamento de cinco plantas fornecedoras de sementes e duas temperaturas de germinação, na ausência de luz: 25ºC constante e 20-30ºC alternada. Os arilos das sementes provenientes de frutos maduros, completamente amarelos, foram extraídos com a utilização de liquidificador em baixa rotação. As características avaliadas nas sementes foram: peso, co… Show more

“…As for the benefit of alternating temperature in the passion fruit seeds germination, this was also reported by Santos et al (1999) in seeds of P. edulis, by Osipi and Nakagawa (2005) in seeds of P. alata and by Zucareli et al (2009) Means followed by the same letter (uppercase in the row and lowercase in the column) do not differ by Tukey test at 5% probability. CV = Coefficient of variation; n.s.…”

“…Zucareli et al (2003) have assessed the germination of Passiflora alata seeds and concluded that, regardless of the treatment used, alternating temperatures between 20 °C and 30 °C has improved the germination. Osipi and Nakagawa (2005) have studied the germination of seeds of different plants of Passiflora alata under two temperature conditions (25 °C and 20-30 °C) and have observed that the alternating temperature 20-30 °C has allowed a higher percentage of germination, regardless of the plant, and have suggested that this may have favored the overcoming of seed dormancy.…”

“…Exposure to low temperatures over a prolonged period can induce seed dormancy in species of the Passifloraceae family (Osipi and Nakagawa, 2005;Zucareli et al, 2009;Zucareli et al, 2015), reduced by the lower speed of water imbibition (Figure 1), without softening of the seed coat and, consequently, lack of protrusion of the radicle (Marini et al, 2012). In addition, it reduces the activity of enzymes related to the germination process -lipase, amylase, and protease -and increases the activity of enzymes related to stress -superoxide dismutase and catalase (Marcos-Filho, 2005;Flores et al, 2014).…”

“…This lack of uniformity is related to the dormancy process present in various species of Passifloraceae, as reported by Osipi and Nakagawa (2005) in Passiflora alata Dryander, by Zucareli et al (2009) in Passiflora cincinnata Mast., and Zucareli et al (2015) in Passiflora incarnata L.…”

“…Ao avaliar o efeito da maturidade do fruto e do seu repouso pós-colheita na germinação de sementes de maracujá doce (Passiflora alata Dryander) em ambiente natural e refrigerador, utilizando frutos em ponto de colheita comercial (início de mudança da coloração verde para amarela, no ápice do fruto) e frutos amadurecidos na planta, próximos ao seu desprendimento, Osipi (2000) verificou que os frutos amadurecidos na planta e submetidos ao repouso em ambiente natural, tanto aqueles maduros quanto no ponto de colheita, propiciaram sementes com melhor qualidade fisiológica.…”
