“…Observa-se que as sementes de milho secas na temperatura de 40 °C (30,21) obtiveram um IVG 2,67 vezes maior que aquelas expostas à temperatura de 100 °C, ratificando o decréscimo na qualidade do produto quando submetido à secagem com temperaturas elevadas. Oliveira et al (2009), avaliando os efeitos imediato e latente da secagem nas temperaturas de 30, 34 e 38 °C em sementes de carambola, não verificaram diferença significativa no IVG com aumento da temperatura de secagem. Ullmann et al (2010), estudando a qualidade fisiológica das sementes de pinhão-manso submetidas à secagem nas temperaturas de 30, 40, 50, 60 e 70 °C, também não verificaram diferença significativa no IVG com aumento da temperatura de secagem.…”

RESUMO: A secagem contribui para a conservação e manutenção da qualidade das sementes, entretanto, dependendo do método e das condições de secagem, tem-se uma redução da qualidade deste produto. Desta forma, objetivou-se com o presente trabalho avaliar o efeito da secagem em diferentes condições de ar sobre a qualidade de sementes de milho. Foram utilizadas sementes da cultivar AG 7088, com teor de água inicial de 19,0 ± 0,3 % base úmida (b.u.), sendo submetidas à secagem em estufa com ventilação de ar forçada em cinco condições de temperatura: 40, 55, 70, 85 e 100 °C. A secagem prosseguiu até que as sementes atingissem o teor de água de 13 ± 0,7% (b.u.). Foram avaliados a taxa de redução de água, germinação, índice de velocidade de germinação (IVG) e a condutividade elétrica para cada temperatura de secagem. Com base nos resultados obtidos, concluiu-se que as temperaturas de secagem superiores a 70 °C diminuem a germinação e o IVG e também aumentam a condutividade elétrica do exsudato das sementes. Para que a qualidade das sementes de milho, cultivar AG 7088, não seja comprometida, a secagem deve ser realizada com a temperatura do ar máxima de 70 °C.

“…Seeds quality must be kept high during storage, aiming at an optimal seedling establishment in the field, in order to guarantee the economic and productive benefits aimed by the producer (Tunes et al, 2014). Drying is a crucial stage of the productive cycle of seeds (Peske & Villela, 2012), mainly employed to reduce the amount of water, delay the deterioration, and make them more suitable for storage (Oliveira et al, 2009). Storage, in turn, aims to preserve the initial quality of the seeds, protecting them from the weather, insects, and microorganisms (Ellis & Hong, 2006).…”

This study aimed to assess the effect of different drying forms, environments, and storage periods on germination and sanitary quality of quinoa seeds cv. BRS Syetetuba. Seeds were submitted to drying in forced air circulation chamber at 30, 40, and 50 °C and in a suspended tray, in full sun, until they reached ±12% of moisture content. The observed drying data were adjusted to 10 mathematical models. The storage for 360 days was continuous in three different environments. Seeds were evaluated at 0, 6, and 12 months for germination, first count of germination, moisture content, and sanity tests. The experimental design was completely randomized, in a split split-plot scheme with four replicates. Among the studied models, Midilli was efficient in describing the drying curves of quinoa seeds. The storage environment influenced the loss of seed quality more than the drying temperature. The increased storage period caused a decrease on fungal seed incidence.

“…The main star fruit producing countries are Taiwan, Malaysia, and Brazil, with an estimated production varying from 3,000 to 40,000 tons of fruits (GOENAGA, 2007). Oliveira et al (2009) estimate that the cultivated area with star fruits in Brazil is approximately 300 ha, located predominantly in the Southeastern region. In this sense, São Paulo State stands out in the national production of star fruit, with a volume of 3,700 tons of fruits negotiated in 2011 by the General Warehouses Company of São Paulo (Ceagesp) (AGRIANUAL, 2012).…”

Among the tropical fruits, star fruit stands out due to its flavor and nutritional properties. Nevertheless, the information on fertilization and nutrition of this fruit is still scarce. For this reason, this study aimed to assess the effect of different boron doses on star fruit rootstock growth. The experimental design was randomized block design, consisting of five treatments of boron application (0, 1, 2, 3, and 4 mg dm−3) and four replications. Star fruit rootstock did not respond to boron doses applied to the substrate and hence it did not influence the parameters stem diameter, plant height, the number of leaves, dry mass of shoot, dry mass of roots, total dry mass, and Dickson quality index (DQI). A boron dose up to 4 mg dm−3 (800% of the recommended boron dose of 0.5 mg dm−3) did not produce symptoms of visual toxicity in the plant.
