Preconditioning of Physalis angulata L. to maintain the viability of seeds

Abstract: The important chemical and food properties conferred to P. angulata make it necessary to conduct studies in seed conservation. This study evaluated the effect of priming of P. angulata seed for varying periods and storage conditions. Lots of seeds were stored in a refrigerator and in ambient conditions for up to 24 months. Some of these seeds were primed before or after storage. The results show that there was variation in moisture content. The germination rate and germination rate index remained high in ambie… Show more

“…Studies related to the physiology of seed germination in species of Physalis have shown that these seeds have high germinability (Pérez Camacho et al, 2008;Rufato, 2008;Souza et al, 2014). In this work, germinability was the only germination parameter that was not significantly different among the species (Table 2).…”

“…(Souza et al 2014). Apesar de possuir sementes ortodoxas, ou seja, tolerantes à secagem até níveis de baixos teores de água, o favorecimento do armazenamento por longos períodos pode depender de outros fatores, como o momento adequado da colheita e o processamento das sementes (Souza et al 2014).…”

“…Souza et al (2014) relataram que a diminuição da viabilidade de sementes ortodoxas, durante o período de armazenamento, é representada por uma curva sigmoide negativa, sendo possível observar outro comportamento das sementes, quando são expostas a combinações inadequadas de temperatura e umidade relativa. Vale ressaltar que os efeitos de temperatura e umidade relativa de armazenamento nas variações nas respostas de sementes podem ser atribuídos a diferenças na sua composição estrutural e bioquímica (Rao et al 2006), associadas ao teor de água inicial das sementes, no período de armazenamento.…”
