“…Luz et al (2012) reported that supplementation of CaSiO 3 , K 2 SiO 3 , or Na 2 SiO 3 to the rooting medium improved leaf anatomy of banana ‘Maca’ plantlets. The inclusion of CaSiO 3 to the culture medium also increased photosynthetic rate and chlorophyll content of banana plantlets (Asmar et al, 2013b). In strawberry, light and electron microscopic analysis showed deformation in chlorenchyma and the epidermis of leaves from plantlets grown in the culture medium devoid of Si (Soares et al, 2012).…”

Growth and morphogenesis of in vitro cultures of plant cells, tissues, and organs are greatly influenced by the composition of the culture medium. Mineral nutrients are necessary for the growth and development of plants. Several morpho-physiological disorders such as hooked leaves, hyperhydricity, fasciation, and shoot tip necrosis are often associated with the concentration of inorganic nutrient in the tissue culture medium. Silicon (Si) is the most abundant mineral element in the soil. The application of Si has been demonstrated to be beneficial for growth, development and yield of various plants and to alleviate various stresses including nutrient imbalance. Addition of Si to the tissue culture medium improves organogenesis, embryogenesis, growth traits, morphological, anatomical, and physiological characteristics of leaves, enhances tolerance to low temperature and salinity, protects cells and against metal toxicity, prevents oxidative phenolic browning and reduces the incidence of hyperhydricity in various plants. Therefore, Si possesses considerable potential for application in a wide range of plant tissue culture studies such as cryopreservation, organogenesis, micropropagation, somatic embryogenesis and secondary metabolites production.

“…The chlorophyll fluorescence parameters including initial fluorescence intensity (Fo), maximal fluorescence (Fm), maximum quantum yield of photosystem II (PSII) (Fv/Fm), photochemical quenching of PSII (qP), nonphotochemical quenching of PSII (NPQ) and quantum yield of PS II (ΦPS II) are widely used in studies on the effects of environmental stress on plants (Abdeshahian et al, 2010;VanDorst et al, 2010). Studying the changes in chlorophyll fluorescence in photosynthesis might help elucidate photosynthetic mechanisms in maize (Asmar et al, 2013).…”

“…Entretanto, apenas nos últimos anos que o fruto verde tem despertado interesse do mercado consumidor, pois, além do seu valor nutricional, com quantidades consideráveis de vitaminas B e C, bem como sais minerais, como potássio e cálcio (LEoNEL et al, 2011;ASMAR et al, 2013), destacam-se a presença de amido resistente (TRIBESS et al, 2009;ALKARKHI et al, 2011), fitoesteróis, compostos fenólicos (HASLINDA et al, 2009;BERToLINI et al, 2010;VERNAzA et al, 2011;SARAWoNG et al, 2014) e capacidade antioxidante (HASLINDA et al, 2009;CHoo & AzIz, 2010;WANG et al, 2012;SARAWoNG et al, 2014).…”

“…é a fruta tropical mais consumida no mundo (SouzA et al, 2011). Pertencente à família Musaceae, apresenta cerca de 30 espécies conhecidas do gênero Musa e mais de 700 variedades (ASMAR et al, 2013). Nutritiva, acessível à maioria da população e disponível o ano todo, é o quarto produto alimentar mais consumido no mundo (SouzA et al, 2011).…”
