“…A acidez titulável em ácido málico não apresentou diferença significativa entre os tratamentos. Mamede et al (2014) analisaram parâmetros físico-químicos de cultivares de milho doce, com uso de adubação convencional, e observaram teor médio de sólidos solúveis de 15,49 °Brix. Comparando-se com esta pesquisa, apenas o tratamento 4 apresentou valor próximo a este, de 15 °Brix; os demais tratamentos apresentaram valores superiores (16 °Brix e 17 °Brix), sendo os grãos do tratamento 2 com maior conteúdo de sólidos solúveis (17 °Brix), o que pode ser uma referência a um maior teor de açúcares.…”

Caracterização pós-colheita de milho doce submetido ao parcelamento de fertirrigação nitrogenada Post-harvest characterization of sweet corn submitted to nitrogen fertigation ResumoA presente pesquisa teve como objetivo avaliar a qualidade pós-colheita do milho doce submetido ao processo de parcelamento do nutriente nitrogênio, aplicado via fertirrigação, através de parâmetros físicos, químicos e sensoriais. A cultivar de milho doce utilizada foi a Doce Cristal (BR-402), sob a influência da fertirrigação em quatro tratamentos, com diferentes parcelamentos de nitrato de amônio, sendo Tratamento 1: 2 aplicações; Tratamento 2: 4 aplicações; Tratamento 3: 6 aplicações, e Tratamento 4: 8 aplicações. As espigas foram avaliadas quanto aos parâmetros físicos de comprimento, diâmetro e massa; físico-químicos de pH, sólidos solúveis, umidade e cinzas; análise sensorial, através do teste de aceitação, além da avaliação instrumental da textura. Nos parâmetros físicos, os tratamentos influenciaram apenas na característica diâmetro das espigas com palha (5,3 cm a 5,8 cm) e sem palha (4,3 cm a 4,7 cm). Nas análises físico-químicas, apenas a acidez titulável em ácido málico não apresentou diferença entre os tratamentos, sendo que os sólidos solúveis apresentaram maior diferença entre os tratamentos, com o Tratamento 4 apresentando 15 °Brix e o Tratamento 2, 17 °Brix. Os tratamentos não influenciaram na aceitação sensorial das espigas de milho doce, as quais apresentaram boa aceitação sensorial para todos os atributos avaliados, com médias hedônicas superiores a 7,3.

AbstractThe aim of this research was evaluate the quality of sweet corn submitted to the nitrogen nutrient installment process applied by fertigation from the physical, chemical and sensory parameters. The cultivar of sweet corn used in the experiment was Doce Cristal (BR-402), submitted to the influence of fertigation in 4 treatments with different installments of ammonium nitrate: Treatment 1: 2 applications, Treatment 2: 4 applications, Treatment 3: 6 applications and Treatment 4: 8 applications. The corn cobs were evaluated for the physical parameters of length, diameter and mass; the physicochemical parameters of pH, soluble solids, moisture and ash; and a sensory analysis using the acceptance test as well as the instrumental texture analysis. For the physical parameters, the treatments only affected the diameter of the ears with (5.3 cm to 5.8 cm) and without (4.3 cm to 4.7 cm) the straw. In the physicochemical analysis only titratable acidity measured as malic acid did not differ between treatments, and the soluble solids showed the greatest difference between treatments with treatment 4 presenting 15 ºBrix and treatment 2 17 ºBrix. The treatments did not influ...

“…The yellow color in green maize, as well as its intensity, may reveal the content of carotenoids present in the cobs. A high content of carotenoids is a very desirable characteristic since it is directly related to the nutritional quality of maize (Mamede et al, 2014). According to Mamede et al (2015), the carotenoid content is directly related to the b* coordinate value, the same authors observed a maximum b* value of 30.36 in green maize with controlled atmosphere on the day 11 of evaluation under refrigeration.…”

Maize is the second most produced grain in Brazil, which has the potential to produce green maize, which is maize harvested before physiological maturation. Aimed with this work evaluate three packages for postharvest conservation of green maize at room temperature in the conditions of the Brazilian cerrado. The double hybrid AG-1051 were planted. After the cobs were harvested, they were submitted to three treatments, each treatment with three repetitions and each repetition contained 4 cobs. The analyzes carried out were: fresh weight loss, instrumental coloring, titratable acidity content, ascorbic acid content and soluble solids. The results were submitted to the 5% Tukey test and regression. The treatment with polyethylene stood out for the loss of fresh mass, color of the maize cobs as for the levels of titratable acidity, presenting the best results and, for the same parameters, the maize cobs of the treatment with straw showed the lowest results, showing that the conservation straw cobs is the least suitable treatment. As for the content of ascorbic acid and soluble solids, the results showed no statistical difference for any of the treatments showing that they kept the contents unchanged during storage.

Super sweet is classified as a special type of corn, due to the presence of genes which promote sugar accumulation in grains, significantly reducing starch content in the endosperm. This study aimed to evaluate the agronomic performance of experimental super sweet corn hybrids, carrying the gene shrunken-2, in order to identify and select promising genotypes for Southern Brazil. The experiments were carried out in two sowing seasons in 2017/18, in the experimental field of UNICENTRO, Guarapuava-PR, Brazil. Thirty-two experimental hybrids resulting from an 8x4 partial diallel among super sweet corn inbred lines from four distinct populations were evaluated along with two commercial hybrids (BRS Vivi and Tropical Plus) used as checks. Traits of agronomic and commercial interest were evaluated: male flowering (MF), husk covering index (HCI), yield of husked ears (YHE), grain yield (GY), commercial prolificacy (CPR), percentage of commercial ears (PCE), color (COL) and soluble solids (SS) of the grains. We verified significant differences among the experimental hybrids, except for COL. There was no significant effect of sowing season regarding to SS. Genotypes x seasons interaction was significant for YHE, GY, CPR, PCE and COL. There are promising experimental hybrids showing performances superior to commercial super sweet corn hybrids used in Brazil. The experimental hybrids D2-61 x D5-41 and D3-10 x D5-43 were superior to the other experimental genotypes. The experimental hybrid D2-61 x D5-41 shows potential to meet the demands of the current super sweet corn market.
