“…According to the adjusted equation, the dose that would provide the greatest formation of somatic embryos, providing an average of 138 embryos per pro-embryogenic mass, would be 0.63 g L -1 of CaSiO 3 . Similar results were reported for embryogenic callus of date palm, in which 0.004 g L -1 of K 2 SiO 3 provided an increase in the number of somatic embryos formed (Abo & Reda, 2014). The growth and development of embryogenic callus of Phragmites australis was also benefited by the supplementation of 0.031-0.062 g L -1 of Na 2 SiO 3 in the culture medium (Máthé et al, 2012).…”

“…For example, the use of Si in culture medium stimulated an increase in chlorophyll content, biomass gain and shoot length in banana (Asmar et al, 2011). In date palm the presence of Si provided greater formation of callus and somatic embryos, increased fresh and dry weight of embryos, as well as reduced oxidation rates and hyperhydricity levels (Abo & Reda, 2014). Despite the biostimulatory capacity of Si (Pavlovic et al, 2021;Trejo-Téllez Gómez-Trejo, & Gómez-Merino, 2023) its effects on E. guineensis somatic embryogenesis are unknown.…”

The use of silicates in plant tissue culture has resulted in positive effects regarding the morphological, anatomical and physiological characteristics of in vitro plants. However, biological responses to this mineral are dose and genotype dependent. The objective of the present study was to evaluate the influence of silicon supplementation on the somatic embryogenesis of oil palm (Elaeis guineensis Jacq.). The study was carried out in three stages of the cloning process, namely: Regeneration (i) and germination (ii) of somatic embryos and during ex vitro acclimatization (iii) of regenerated plantlets. The culture media were supplemented with four doses (0.0, 0.5, 1.0 and 1.5 g L-1) of calcium silicate (CaSiO3). The resulting plantlets were transplanted and acclimatized in a greenhouse. The regression analysis showed that the dose of 0.63g L-1 of CaSiO3 induced a higher rate of regeneration, which would allow a 58% increase in the number of somatic embryos formed. However, the germination of the plantlets, as well as their morphometric characters, were not affected by the different doses of CaSiO3, although the presence of this compound promoted an increase in the thickness of the epidermis and a reduction in the amount of epicuticular wax. Overall, silicon does contribute to the cloning of E. guineensis.

“…The findings obtained at this phase, in which the roots were not formed, yet, suggested that the presence of roots is necessary for the silicon to be effective. The thought that silicon is an ineffective element on plant growth and development cannot be clearly supported at this stage in our opinion (El Fadl and Reda, 2014).…”

“…While Soares et al (2011) also reported that the addition of 5.0 mg L -1 K 2 SiO 3 and 20.0 mg L −1 Na 2 SiO 3 to modified Knudson C medium increased shoot length and number of shoots in orchid plants, Manivannan et al (2018) observed that potassium silicate was more effective than calcium silicate on clove plant cultured in vitro in MS environment containing three different concentrations (0, 1.8 or 3.6 mM) of potassium and calcium silicate. El Fadl and Reda (2014) reported that in the dry date Bartamuda, fresh and dry weight increased in the presence of potassium and sodium silicate. Avestan et al (2016) have obtained in their study on MM106 apple rootstock the highest plant fresh and dry weight and chlorophyll level from the mediums containing 100 mg L -1 nano-silicon.…”

“…According to some researchers, although silicon is not among the essential elements for plants (Ma, 2004;Soares et al, 2008), there are also studies reporting that many plants benefit from this element (Epstein, 1994) and that silicon plays a beneficial role in stimulating the growth and development of many plant species (Avestan et al, 2016;Sahebi et al, 2016;Costa et al, 2021).…”

Silicon, which is widely used in different fields, has been used in plant production in vivo and in vitro studies in recent years. Especially in in vitro studies, it is seen that its effect on plant growth and development has been examined. In this study, the effect of three different silicon sources and their four concentrations on micro-propagation of 140 Ru grape rootstocks was investigated. In the study, as explants one-node micro cuttings of rootstock and MS (Murashige and Skoog) as the nutrient medium were used. 1 mg L -1 BA (Benzyl Adenine) at the stage of obtaining shoots from cuttings and in the rooting stage, 1 mg L -1 IBA (Indole Butyric Acid) were added to the nutrient medium. At both stages, 0 (Control), 0.5, 1.0 and 2.0 mg L -1 doses of potassium, sodium and calcium silicate were added to the nutrient medium. Explant viability and mortality rate, shooting rate, plant length, node number, shoot fresh and dry weight, chlorophyll content (SPAD), root number, root length, root fresh and dry weight were examined to determine the effect of the applications. The variance analysis of the study was carried out according to the Two-Way Completely Randomized Experimental Design. According to the results, among the silicon sources, the highest shooting rate (84.40%) was found in the medium containing sodium silicate. The highest shoot fresh and dry weight (0.178 g and 0.026 g, respectively) and root fresh and dry weight values (0.213 g and 0.023 g, respectively) were obtained from potassium silicate. While the number of roots was 2.98 in the medium containing potassium, it was determined as 2.91 in the medium containing calcium silicate. Media containing 1 mg L -1 silicate was found to be more successful than 0, 05, 2 mg L -1 concentrations. The highest values recorded at the concentration were 4.49 cm in plant length, 7.44 in node number, 0.183 g and 0.028 g in shoot fresh and dry weight, respectively, 28.37 in SPAD value and 3.27 in root number. As a result of the study, it is concluded that adding 1 mg L -1 concentration of potassium, calcium and sodium silicate to the nutrient medium can be used in future studies related with in micro propagation.
