“…The MI is inversely proportional to the titratable acidity, which is related to the fact that the organic acids are used during maturation process, either through respiration or transformation into sugars (Lombardi;Moraes;Camelatto, 2000;Matarazzo et al, 2013). In a research conducted with tomatoes, Zhu et al (2017) observed lower fruit maturation rates when plants were treated with 1 mg L -1 of Se in the form of selenite.…”

The selenium (Se) is essential for human metabolism, but a large part of the world's population has deficiency in this element. This can be reversed by the consumption of biofortified foods, given that plants can efficiently act in controlling excessive and/or accidental consumption of an element that can occur in humans through the use of dietary supplements. The objective of this study was to evaluate the effect of different application forms and sources of Se in the growth, production, nutrition, physical-chemical characteristics, content and accumulation of Se in carrots. The experiment was conducted under greenhouse conditions, using pots containing 4 dm 3 of Red-yellow Latosol. A completely randomized design was used in a 2x2x2 factorial scheme (with and without Se application, two sources of Se: selenate and selenite, two forms of application of Se: soil and foliar applications), with five replicates. Foliar application of selenate increased the yield and titratable acidity, reducing root ripening index. Foliar application of selenite increased the content of Se in the shoots and the content of carotenoids in the roots. Both sources of Se (selenate and selenite) and application forms (soil or foliar application) increased their content in the roots. However, the foliar application of selenate was the most effective source and form of application. Therefore, it is possible to increase the contents of Se in the edible part of carrots, favoring the consumption of this element by the population. Index terms:Daucus carota Lam; selenate; selenite; maturation index; carotenoids. RESUMOO selênio (Se) é essencial para o metabolismo humano, porém, grande parte da população mundial apresenta deficiência nesse elemento. Isto pode ser revertido pelo consumo de alimentos biofortificados, uma vez que as plantas podem atuar de forma eficiente no controle do consumo excessivo e / ou acidental de um elemento que pode ocorrer nos seres humanos através do uso de suplementos dietéticos. Objetivou-se com o presente estudo avaliar o efeito de formas de aplicação e fontes de Se no crescimento, produção, nutrição, características físico-químicas, teor e acúmulo de Se na cenoura. O experimento foi desenvolvido em casa de vegetação, utilizando vasos com quatro dm 3 contendo Latossolo Vermelho Amarelo. Adotou-se o delineamento inteiramente casualizado, em fatorial 2 x 2 x 2 (com e sem aplicação do Se; duas fontes do Se: selenato e selenito; duas formas de aplicação do Se: via solo e foliar), com cinco repetições. O selenato aplicado via foliar aumenta a produção e a acidez titulável e reduz o índice de maturação das raízes. O selenito via foliar aumenta o teor de Se na parte aérea e o teor de carotenoides nas raízes de cenoura. As duas fontes de Se (selenato e selenito) e formas de aplicação (via solo ou foliar) promovem aumento do seu teor nas raízes de cenoura, porém o selenato via foliar é a fonte e forma mais efetiva. Dessa forma, é possível aumentar os teores de Se na parte comestível da cenoura e, assim, favorecer a in...

“…5); de igual manera, este incremento en los ácidos orgá-nicos durante la maduración, podrían dar explicación sobre la dinámica de la ATT para las dos variedades. De otra parte, Yahia et al (2001) sugieren que la baja actividad enzimática del ácido ascórbicooxidasa en los frutos, permite que las concentraciones de vitamina C sean mayores, ya que esta es la responsable de la degradación oxidativa del ácido ascórbico en tejidos vegetales durante el proceso de maduración (Matarazzo et al, 2013), lo que explica lo encontrado en esta investigación.…”

RESUMENEl lulo (Solanum quitoense Lam.) se ha considerado frutal promisorio y especie potencial para mercados globales, constituyéndose en un renglón importante para la economía del departamento de Boyacá (Colombia). La presente investigación buscó realizar una caracterización fisicoquímica de los frutos de dos variedades de lulo (Chonto grueso y Criollo) durante su crecimiento y desarrollo, procedentes del municipio de Pachavita, Boyacá. Para ello se tomaron frutos cada 10 días, a partir de los 30 días después de antesis (dda). Se evaluó la masa fresca, acidez total titulable (ATT), sólidos solubles totales (SST), firmeza y tasa respiratoria (TR). Se encontró que los frutos de las dos variedades presentaron un crecimiento tipo sigmoide simple que se ajustó a un modelo de crecimiento logístico, apreciándose tres fases de crecimiento que se describieron como: Fase I de división celular; Fase II de elongación celular; y Fase III de maduración. Las propiedades químicas se ajustaron a modelos polinómicos, donde la ATT y los SST aumentaron progresivamente, mientras que la TR se redujo siguiendo las características propias de los frutos de lulo, logrando la calidad organoléptica requerida para el consumo.Palabras clave adicionales: fenología, solanaceae, días después de antesis, tasa respiratoria.

AbstrAct:The nutritional importance of the fruit of passionfruit has prompted studies to assess its composition and antioxidant content and to evaluate it as a functional food in fresh fruit and concentrated juice markets. Currently, the use of wild species as rootstock has been recommended mainly for their positive effects such as tolerance to disease attack and maintenance of fruit quality of grafted cultivars.The aim of this study was to determine the effect of wild species of on the same species were used. Significant correlations were observed among the contents of β-carotene, ascorbic acid, luminosity values, chroma and hue angle. For the combination P. edulis/P. gibertti, the contents of β-carotene and ascorbic acid were highly correlated with luminosity, chroma and hue angle of fruit juice. A similar behavior was observed for the combination P. edulis/P. mucronata Lam. The content of β-carotene in the fruit showed no statistical differences (p < 0.05), indicating no significant rootstock effect on the variables evaluated.The results indicate a potential wild rootstock use for its positive effects on grafted plants while maintaining the commercial quality of the fruits of passionfruit crops.
