Abstract: Silicon (Si) fertilizers have been increasingly used in agriculture due to several benefits as acidity correction in tropical soils and positive effects on the development of grasses. Nutrient availability and plant nutrition play an important role in seed production and may affect the physiological quality of white oat seeds. The present study had as objective to evaluate seed germination and seedling development of white oat (Avena sativa L.) affected by silicon and phosphorus fertilization. The experimental… Show more

“…Esses resultados estão de acordo com os verificados por Rafi et al (1997), com sementes de trigo, concluindo-se que a presença de silício resulta em aumento da capacidade biológica das sementes e plântulas, para resistirem às condições adversas do ambiente, ou a algum estresse (testes de vigor), como ocorreu nesta pesquisa. Esses resultados também estão de acordo com os encontrados por Toledo et al (2011), que verificaram a ação de fontes de silício em testes de vigor de sementes de aveia. Para o cultivar Puitá, foram detectados fungos, como Epicocum, Alternaria sp.…”

“…In the interrelation of soil elements, the availability of a specific ions may condition the effect of other elements on seed development. This was the case of P fertilization that affected the silicon (Si) action on seed quality [48]. The authors observed in white oat (Avena sativa L.) plants that Si had an interactive effect with P at elevated P concentrations (200 mg dm −3 of P 2 O 5 ).…”

“…(c) Most of the chemicals which promote germination up to certain concentrations are known to inhibit it when present in higher concentration [50][51][52]. Chemical fertilizers also display this dichotomy-facilitating germination and growth up to certain levels of application and hindering the same at higher levels [53][54][55]. (d) Elevated salinity, caused by the higher mineral content of VC, perhaps slows down water uptake by seeds, thereby inhibiting their germination and root elongation [56][57][58].…”
