Nutrição mineral de plantas ornamentais I : absorção de nutrientes pela cultura de gladíolos

Abstract: RESUMOBulbos de gladíolos (Gladiolus communis, var. Ita¬ petininga) foram postos a germinar em vasos com capacidade de 7 kg de silica. Após a germinação, as plantas foram irriga¬ das com solução nutritiva completa de HOAGLAND & ARNON (1950). Quinze dias, após a germinação e em períodos de 10 dias subsequentes, plantas foram coletadas e divididas em: parte aé-rea, bulbo velho, bulbo em formação e bulbilhos. Os materiais foram pesados e analisados para nitrogênio, fosforo, potássio, calcio, magnésio, enxofre, bo… Show more

“…Woltz (1954) found that the decreasing order of macronutrients in the 'Elisabeth The Queen' gladiolus was K > N > Ca > P > Mg, while the order of micronutrients was Fe > Mn > Cu. Haag et al (1970) found that the 'Itapetininga' gladiolus presented the following order of leaf macronutrients at flowering: K > N > Ca > P > S > Mg. In the case of micronutrients, the order was the same as in the present study.…”

“…Carvalho et al (2013) found that the application of Si to the Dendrobium nobile orchid increased flower production and longevity. Ornamental plants, such as aster, clove, chrysanthemum, geranium, sunflower, petunia, rose, vinca and zinnia, accumulate Si in their tissues in amounts ranging 0.21-32.8 g kg -1 , depending on the species (Carvalho et al 2009, Hogendorp et al 2012, Zanão Júnior et al 2013, Park et al 2016. Beneficial effects of supplemental Si have been observed in many of these species, and these effects vary and strongly depend on the species, and even the cultivar (Jana & Jeong 2014, Park et al 2016 Many substrates for ornamental plants contain very low levels of plant-available Si.…”
