“…was applied, clearly show that foliar-applied Mo increases the SMoCc substantially, as observed by Vieira et al (2005Vieira et al ( , 2010, Pacheco et al (2012), and Almeida et al (2013). The SMoCt ranged from 1.75 (Valente, Figure 2a) to 11.2 µg per seed (Jalo MG-65, Figure 1b).…”

“…This Mo rate seems sufficient to increase Mo in seeds of Type III genotypes such as Majestoso, VC-8, Ouro Vermelho, and Madrepérola to 3.6 µg, even in soil with pH 4.7 (as in Coimbra), where the Mo available in soil is 100 times lower than in soil with pH 5.7 (Lindsay, 1979). In a soil with pH 5.2 in Coimbra, Vieira et al (2010) sprayed plants of cultivar Pérola with 1000 g ha -1 Mo to obtain 3.6 µg Mo per seed. In the present study, Pérola was not among the genotypes with high capacity to accumulate Mo in seed, helping to explain the high Mo rate used by Vieira et al (2010) to obtain 3.6 µg Mo per seed.…”

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. Without Mo application, the average SMoCc was undetectable or 2.83 µg g -1 , without significant differences among genotypes. On average, with Mo applications, SMoCc ranged from 14.7 to 25.0 µg g -1 and SMoCt, from 3.94 to 6.84 µg. 'Majestoso' was among the genotypes with the highest SMoCc in the four experiments. However, the large-seeded 'Jalo MG-65' and 'Carnaval' generally had higher SMoCt than the small-seeded 'Majestoso'. 'Ouro Negro' and especially 'Valente' were among the genotypes with the lowest SMoCc and SMoCt. The values of these variables were 61 and 90 %, respectively, higher for 'Majestoso' than those for 'Valente'. Our results suggest that common bean genotypes differ in their capacity to accumulate foliar-applied Mo in the seeds. Mo-rich seeds of large-seeded genotypes or of small-seeded of small-seeded genotypes with good capacity to accumulate Mo in seeds can be produced with relatively less Mo fertilizer.Index terms: Phaseolus vulgaris, seed molybdenum content, foliar fertilization, growth habit.(

“…There are no reports in the literature of the depressant effect of Mo on FS in the bean, and so it is believed that this result could not have been caused by the application of the Mo dosages together with the glyphosate. Leite et al (2007), applying dosages of from 0 to 2.56 kg Mo ha -1 , and Vieira et al (2010), applying dosages from 0 to 4.00 kg Mo ha -1 via the leaves in the bean, also found no decrease in FS or symptoms of toxicity in the plants.…”

“…Também indica que 255 g ha -1 de Mo aplicados em R7 (depois de 255 g ha -1 em R6) podem reduzir a qualidade fisiológica das sementes. Em outro estudo, conduzido na Zona da Mata, a aplicação de 1000 g ha -1 de Mo, aos 71 DAE (fase R7), não influenciou significativamente a germinação das sementes ( Vieira et al, 2010). Logo, mais estudos com combinações de doses de Mo aplicadas em R7 são necessá-rios para esclarecer essa questão.…”

A aplicação foliar de molibdênio na fase de enchimento de vagens do feijão-comum pode reduzir a qualidade da sementeCom o objetivo de aprimorar a tecnologia de produção de sementes ricas em molibdênio (Mo), foram avaliados os efeitos da aplicação foliar de 600 g ha -1 de Mo na qualidade fisiológica da semente de feijão. Em campo, essa dose de Mo foi aplicada na fase V4 (terceira folha trifoliolada), ou parcelada de duas a quatro vezes e aplicada em V4, R6 (floração), R7 e, ou, R8 (enchimento de vagens). A aplicação de 300 g ha Foliar molybdenum applied to common bean pod filling may reduce seed qualityAiming to improve the technology of producing seed with high Mo content, the effects of 600 g ha -1 of foliar-applied Mo on common bean seed quality were evaluated. In the field, this Mo rate was applied at the V4 growth stage (third trifoliolate leave) or divided into two or four rates applied at V4, R6 (flowering), R7 and/or R8 (pod filling). Mo (300 g ha -1) applied at R6 did not affect seed quality relative to control (90 g ha -1 of Mo applied at V4). In the three treatments in which 200, 255 or 300 g ha -1 of Mo were applied at R7, only in one (255 g ha -1 ) Mo decreased seed germination and vigor relative to control. When 200, 255 or 300 g ha -1 of Mo were applied at R8 (five treatments), in general, Mo decreased seed germination and, in two cases, also seed vigor relative to control. It was concluded that 255 g ha -1 of Mo applied at R7 and, especially, doses of 200 g ha -1 of Mo or higher applied at R8 can reduce common bean seed quality.
