“…In seeds of C. anguria, the germination test lasts for a period of 8 days (Brasil 2009), a relative long period when considering a decision-making process. Thus, the use of vigor tests is essential, once these are consistent and produce rapid information concerning processes of physiological deterioration in seeds (Catão et al 2019).…”

Gherkin seeds usually show irregular physiological quality. Seed production requires fast and reliable tests to evaluate seed quality. Germination test is considered a recognized analysis method; however, seed technology has pursuit the improvement of vigor tests aiming the evaluation of seed’s physiological potential. Thus, the objective of this work was to evaluate procedures to perform the test of accelerated aging and determine the physiological and sanitary potential of gherkin seeds. Four seed lots of cultivar Liso Calcuta were used in the study. To evaluate the initial physiological quality the water content was determined and germination and emergence tests, as well as indices of germination speed and emergence speed were used. The accelerated aging test was performed as traditionally and with saturated saline solution, with 48, 72 and 96 hours, at temperatures of 41oC and 45oC. After aging, the water content was determined, and seeds’ germination and sanity tests were performed. The experiment was set under a completely random design in factorial 4x3x2 (lots x aging periods x temperatures). The standard accelerated aging test and the test with saturated saline solution at 41oC for 96 hours were efficient to evaluate the vigor of gherkin seeds. Saturated saline solution provides uniform water absorption and deterioration in gherkin seeds, allowing to discriminate seed lots in different vigor levels. The salinity test after accelerated aging with saline solution reduces the incidence of some fungi.

“…Seed production is considered scarce when compared with other vegetables and those seeds generally exhibit low quality. The utilization of seeds with high physiological potential is important to set up crops (Kavan et al 2019) once it enables higher yield (Catão et al 2019).…”

“…The use of seeds of good physiological quality is important to ensure that after sowing, the grains continue to develop and become productive (Catão et al, 2019;Lopes et al, 2018). All stages, from seed selection to cultivation, harvest, and postharvest, when not conducted properly, can negatively affect the nutritional and technological quality of the grains.…”

O consumo de pipoca aumenta progressivamente em todas as regiões do mundo. Variedades crioulas de milho pipoca são cultivadas pela agricultura familiar. Objetivou-se caracterizar uma variedade crioula de milho pipoca (VCP) cultivada em sistema orgânico pelos agricultores familiares. Análises realizadas: caracterização fenotípica e identificação da raça, germinação e vigor; relação espessura/largura, índice de circularidade, esfericidade, diâmetro médio geométrico, relação de diâmetro, volume, área de superfície, ângulo de repouso (AR), massa específica (MEA), peso hectolitro (PH), peso de mil grãos (PMG), cor e classificação conforme requisitos de identidade e qualidade. A VCP é de origem indígena Guarani e pertence à raça Avatí Pichingá Ihú. A variedade apresentou elevado percentual de plântulas normais e pode ser utilizada como semente. As dimensões e os índices calculados apresentaram variação importante entre os grãos, demonstrando ampla diversidade genética, típico de variedades crioulas. O AR baixo, associado às dimensões, caracterizou os grãos da VCP de tamanho pequeno. Os valores superiores para PH, MEA e PMG indicaram maiores teores de endosperma vítreo, dureza e conteúdo de amido. As coordenadas a* e b* indicaram cor vermelha e tendência ao amarelo, respectivamente. O valor baixo para o parâmetro L* indicou cor intensa da VCP. O milho foi classificado como tipo 1 conforme percentual de defeitos físicos, porém a capacidade de expansão apresentou valor abaixo da referência para comercialização. Verifica-se o potencial da variedade estudada para ser usada pelas indústrias, principalmente alimentícia. Pode-se estimular seu cultivo pela agricultura familiar, causando impacto na produção regional do grão e promovendo o resgate do germoplasma.
