“…The application of Si has been reported to affect the tissue nutrient concentrations of many plant species such as alfalfa (Wang and Han, 2007), bean (Zuccarini, 2008), chrysanthemum (Sivanesan et al, 2013), gerbera (Kamenidou et al, 2010), and rice (Guo et al, 2005). In the present study, 100 mg･L -1 Si treatment reduced both frond and root tissue concentration of Ca by 14.9 and 14.0%, respectively, compared with the control.…”

“…Silicon has been reported to be beneficial for growth and development of graminaceous plants such as rice, sugarcane and wheat (Liang et al, 2007). However, recent studies have shown that the Si nutrition enhanced growth traits in carnation (Bae et al, 2010), chrysanthemum 'Backwang' (Moon et al, 2008), gerbera (Kamenidou et al, 2010;Savvas et al, 2002), kalanchoe (Bae et al, 2010), sunflower (Kamenidou et al, 2008), rose (Ehret et al, 2005;Hwang et al, 2005), and zinnia (Kamenidou et al, 2009). Furthermore, application of Si has been shown to be able to control diseases (Rodrigues et al, 2003;Voogt and Sonneveld, 2001) and pests (Jeong et al, 2012;Ranganathan et al, 2006), alleviate toxicity of some heavy metals (Shi et al, 2010), and enhance resistance to drought (Chen et al, 2011), salinity (MateosNaranjo et al, 2013), and temperature stresses (Epstein, 1999;Ma and Yamaji, 2006).…”

Effect of silicon (Si) nutrition on growth and temperature stress tolerance of Nephrolepis exaltata 'Corditas' grown in a soilless substrate was examined. In vitro-grown acclimatized plantlets were transplanted into the pots containing a coir-based substrate. A nutrient solution containing 0, 50, or 100 mg･L -1 Si was supplied through a drip-irrigation system. After 5 months of cultivation, Si-treated and -untreated plants were grown at 10, 25, or 40 ± 1°C under a 12 h photoperiod with 530 µmol･m PPFD and 60% RH. After 7 days, chlorophyll content and chlorophyll fluorescence parameters were measured. Silicon nutrition had a negative effect on growth characteristics of N. exaltata 'Corditas'. However, Si-treated plants had more tolerance to temperature stress than the control plants. The Fv/Fm value was not significantly different when the plants were exposed to 25°C. However, significant difference in Fv/Fm was recorded when plants were exposed to 10 or 40°C. Thus, Fv/Fm could be used as an indicator of low and high temperature tolerance in ferns. The present study also suggests that application of Si may be used to enhance temperature tolerance of ferns.

“…However, in this study, applying Si induced a reduction of the length and diameter of stems and floral bud in relation to the control, as reported by Reezi et al (2009), who observed that with high doses of Si (150 ppm), there was a noticeable reduction in the length and diameter of rose stems. Likewise, it has been documented that applying potassium silicate (200 mg L -1 ) in sunflower (Helianthus annuus L.) causes deformity in flowers and hinders growth (Kamenidou et al, 2008), whereas applying sodium silicate (150 mg L -1 ) reduces the length of stems and causes deformity in gerbera flowers (Kamenidou et al, 2010). Another possible explanation is that the addition of Si in plants could improve biotic or abiotic stress or alter their morphology (Ma and Yamaji, 2006), as observed in thie present study.…”

“…Así también, se ha documentado que la aplicación de silicato de potasio (200 mg L -1 ) en girasol (Helianthus annuus L.) provoca la deformación de flores y retrasa el crecimiento (Kamenidou et al, 2008), mientras que cuando se aplica silicato de sodio (150 mg L -1 ) disminuye la longitud de tallos y causa deformación en flores de gerbera (Kamenidou et al, 2010). Otra posible explicación es que el suministro de Si en las plantas puede beneficiar en la mejora a la resistencia al estrés biótico o abiótico o altera la morfología de las mismas (Ma y Yamaji, 2006), tal como se observó en este estudio.…”

Resumen. La cenicilla del rosal causada por Podosphaera pannosa afecta todas las partes aéreas de la planta, lo que repercute en su calidad como principal componente de la pérdida económica. En el presente trabajo, se confirmó la identidad del agente causal de la cenicilla en rosa y se evaluó el efecto del fosfito de potasio (K 3 PO 3 ), silicio, quitosano y acetato de dodemorf sobre la incidencia y severidad de la enfermedad, así como, su respuesta en la calidad de tallos florales. Se realizaron dos ensayos (febrero-abril y mayo-julio). Las caracterís-ticas morfométricas y moleculares del agente causal de la cenicilla correspondieron a Podosphaera pannosa. El K 3 PO 3 , silicio y quitosano redujeron Abstract. Rose powdery mildew caused byPodosphaera pannosa affects all aerial parts of the plant, which affects their quality as a major component of economic loss. In this work, the causal agent of powdery mildew of rose was identity and confirmed, the effect of potassium phosphite (K 3 PO 3 ), silicon, chitosan and dodemorph acetate on the incidence and severity of the disease was evaluated, as well as their response in the quality of flower stalks. Two trials (February to April and from May to July) were performed. The morphometric and molecular characteristics of the causal agent corresponded to Podosphaera pannosa. The K 3 PO 3 , silicon and chitosan they reduced incidence and severity compared to the control for both assays, however, only the K 3 PO 3 and silicon, exhibited a control similar to provided by the fungicide dodemorph acetate. The treatment with chitosan increased the length and diameter of the stem and flower bud in contrast to K 3 PO 3 and silicon, but was not significant to the control in both tests. Based on the results, the K 3 PO 3 , silicon and

A utilização de Si no cultivo de algumas plantas ornamentais cultivadas em vasos em casa de vegetação tem proporcionado aumento na produção e qualidade do produto final. Objetivou-se com este estudo avaliar a produção e absorção de nutrientes de dois cultivares de roseira cultivados em vasos influenciados pela aplicação de doses de Si no substrato. Os tratamentos foram gerados pelo fatorial 2 x 5, composto por dois cultivares de roseira (Yellow Terrazza® e Red White Terrazza®) e cinco doses de Si (0; 0,25; 0,50; 0,75; e 1,00 g kg-1), e dispostos em delineamento de blocos casualizados, com quatro repetições. Foram avaliados altura, ciclo, produção, diâmetro, longevidade floral, teores e conteúdos foliares de Si, macro e micronutrientes da planta. Foi feita a análise de variância dos dados, ajustando-se equações de regressão para o efeito das doses de Si. A aplicação de Si no substrato melhorou a produção e qualidade das rosas produzidas em vasos em casa de vegetação, porém a resposta das plantas variou com as doses de Si. As doses de Si para se obterem 90 % da produção máxima de matéria seca de flores foram de 0,43 e 0,22 g kg-1 para Yellow Terrazza® e Red White Terrazza®, respectivamente. Já os efeitos negativos do elemento foram observados a partir das doses de 0,86 e 0,55 g kg-1 de Si para Yellow Terrazza® e Red White Terrazza®, respectivamente. Os teores foliares de Si aumentaram em função da dose de Si aplicada no substrato.
