Genotypic variability in seed accumulation of foliar-applied molybdenum to common bean

Abstract: SUMMARYThe genotypic variability in molybdenum (Mo) accumulation in common bean seeds has been demonstrated in cases in which soil is the main Mo source, but this variability is yet unknown when Mo is foliar-applied. Therefore, seed Mo concentrations (SMoCc) and seed Mo contents (SMoCt) of 12 genotypes were determined in four experiments in the Zona da Mata, Minas Gerais, Brazil, in which plants were sprayed with 600 g ha -1 Mo. For comparison, two additional experiments without external Mo were conducted. Wit… Show more

“…This difference in soil pH helps to explain the higher SMoC in Oratórios. SMoC means obtained in this study with the split of 600 g Mo ha -1 were somewhat higher compared to those obtained by Vieira et al (2014) in the same area, with the same cultivar and also applying part of the Mo at the reproductive stage.…”

“…The dose of 600 g Mo ha -1 was used to produce Mo-rich seeds of the common bean (Vieira, Paula Júnior, Carneiro, & Queiroz, 2014). The latter dose was also split as follows: 100(V4)+500(R5), 100(V4)+500(R7), 100(V4)+250(R5)+250(R7), and 100(V4)+150(R5) +350(R7).…”

“…Usou-se o cultivar BRSMG Majestoso, do grupo comercial carioca e de hábito de crescimento indeterminado (tipo III), que é bom acumulador de Mo na semente ( Vieira et al, 2014) Avaliaram-se estande final, produtividade, massa de 100 sementes, germinação e vigor das sementes colhidas. A produtividade e a massa de 100 sementes foram obtidas com sementes com aproximadamente 13% de água (base úmida).…”

“…Na Zona da Mata, 600 g ha -1 de Mo geralmente elevam o conteúdo de Mo para pelo menos 3,6 µg por semente (Vieira et al, 2014), teor com que os feijoeiros não mais respondem à aplicação de Mo na folhagem ( Vieira et al, 2011). Nessa região, o conteú-do de Mo da semente de feijão quase dobrou quando a dose de 1440 g ha -1 de Mo foi dividida em quatro subdoses e aplicada entre V4 (terceira folha trifoliolada) e R5 (pré-floração), em comparação com o efeito da aplicação única em V4 (Vieira et al 2005).…”
