“…The aforementioned results of flower longevity are similar to those of Carvalho et al, (2013) on Dendrobium nobile orchid and Babalar et al, (2016) on gerbera. And, the obtained data of number of the flowers per inflorescens were in agreement with those obtained by Khenizy and Ibrahim (2015) The increases of flower diameter and flower fresh and dry weight might be due to the role of silicon in reducing evapotranspiration (Lu and Cao, 2001;McAvoy and Bernard, 1996), which could have contributed to increase turgor pressure within the flower, resulting in cell swelling and thus larger flower diameters, which lead to increasing flower fresh and dry weight.…”

Two pot experiments were carried out during the two successive Winter seasons of 2015/2016 and 2016/2017. The experiments were executed in a private commercial nursery located at Damanhour City, El-Beheira Governorate, Egypt under greenhouse conditions. The objective of this research was to evaluate the effect of silicon (Potassium silicate; Si) as a spray, or a soil drench at concentrations of 0, 5 and 7.5 mmol in enhancing Narcissus tazetta L. growth, flower production, and quality. The experiment was conducted as a split-plot in a randomized complete block design (RCBD). The obtained results of the two seasons, generally, showed that application of silicon as soil drench at 7.5 mmol recorded the highest mean values of the most data recorded and might be considered as optimal treatment for the production of high yield and quality of narcissus plants under the environmental conditions of Beheira Governorate and other similar regions.

“…Avaliando alface americana minimamente processada, Galati et al (2015) observaram que a concentração de 84 mg/L de silício propiciou maior firmeza das folhas, deixando-as mais túrgidas e conservando sua vida útil por 16 dias. Em plantas de Dendrobium nobile, o fornecimento de 0,45 g/L de SiMg promoveu o aumento da longevidade de flores em quatro dias (CARVALHO et al, 2013).…”

A alface (Lactuca sativa L.) é uma folhosa altamente consumida e apresenta vida pós-colheita curta, gerando assim muitas perdas e prejuízos. Na horticultura, o uso do silício tem demonstrado efeito benéfico da sua utilização em diversas plantas. Nesse sentido, o objetivo desse trabalho foi verificar a influência da aplicação foliar de doses crescentes de silicato de magnésio na produção e conservação pós-colheita da alface crespa. O silício por possuir relação direta na preservação contra danos oxidativos e na manutenção dos teores de clorofila, proporcionou um retardo à senescência e consequentemente uma melhor conservação pós-colheita da alface, prolongando por dois dias a sua vida útil na dose de 0,32 g/L. Porém, a aplicação de silicato de magnésio não promoveu o crescimento da alface crespa. Palavras-chave: Lactuca sativa L.. Horticultura. Perecibilidade. Nutriente. Silicato de magnésio. SILICON PROMOTES BETTER POST-HARVEST CONSERVATION OF LETTUCE ABSTRACT Lettuce (Lactuca sativa L.) is a heavily consumed hardwood and presents a short post-harvest life, thus generating many losses. In horticulture, the use of silicon has shown beneficial effect of its use in several plants. In this sense, the objective of this study was to verify the influence of foliar application of increasing doses of magnesium silicate on the production and post-harvest conservation of crisp lettuce. Due to its direct relationship in the preservation of oxidative damage and the maintenance of chlorophyll content, silicon provided a delay in senescence and a better postharvest conservation of the lettuce, extending its shelf life by 0.32 g/L. However, the application of magnesium silicate did not promote the growth of crisp lettuce.

“…The main positive effects also include flowers with better quality and greater longevity (Jana & Jeong 2014). 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.…”

Gladiolus is among the most traditional and important cut flowers in Brazil. Silicon (Si) is an element that has increased the production and quality of some ornamental plants. This study aimed at evaluating the production and nutritional status of gladiolus cultivars under greenhouse conditions, according to the Si doses applied to the substrate. The experimental design was randomized blocks, in a 3 x 4 factorial scheme, being three gladiolus cultivars ('White Friendship', 'Rose Friendship' and 'Red Beauty') and four Si doses (0 mg dm-3, 150 mg dm-3, 300 mg dm-3 and 600 mg dm-3), with five replicates. Morphological traits and leaf Si, macro and micronutrients were evaluated. 'White Friendship' and 'Red Beauty' developed taller plants, with a higher diameter and spikes heavier and longer than 'Rose Friendship'. The order of leaf nutrient concentrations for all the cultivars evaluated was the same (K > N > Ca > Mg > S > P > Fe > Mn > B > Zn > Cu), with all of them being classified as Si non-accumulators. Neither the evaluated morphological variables, nor the uptake of the nutrients N, P, K, Ca, Mg, S, B, Cu, Fe, Mn and Zn, were affected by the Si supplementation, suggesting that the addition of Si to the substrate does not enhance the gladiolus production.
