“…The in vitro cultures were maintained in culture jars (15 mL of medium per vessel) at 23 ± 2 • C under a 16 h photoperiod with 40 µmol m −2 s −1 light intensity provided by cool white fluorescent lamps (Philips, Pila, Poland). For ex vitro acclimation, the microclones were cultivated in plastic trays where individual tray cells (90 cm 3 ) contained peat with 20% of perlite (pH 5.5-6.0) and a coconut substrate (at 1.0:0.5, v/v) during 4 weeks in accordance with Ambros et al [23].…”

“…In strawberry leaves, phenolic compounds from several classes have been identified: hydroxybenzoic and hydroxycinnamic acids, ellagic acid derivatives (including ellagitannins), catechins, and flavonols [20,21]. Previously, we investigated the phenolic profile of strawberry leaves and its changes throughout plant development in tissue culture, including under the influence of a silicon-based biostimulant; we revealed upregulation of some phenolic acids and ellagic acid derivatives [22,23].…”

“…Alterations of the phenolic profile have been associated with other considerable physiological transformations: enhanced antioxidant enzymatic activity, vegetative growth, dry matter production, and formation of photosynthetic pigments, as well as reduced hydrogen peroxide accumulation and modulation of concentrations of endogenous plant growth regulators [9,[23][24][25]. Some authors have suggested that the silicon-stimulated production of flavonoids and organic acids may be a strategy used by plants to cope with exogenous stressors [26][27][28].…”

The positive effect of silicon on plants is thought to be mediated by a modification of phenolic metabolism. The purpose of the study was to evaluate the effect of a silicon-based mechanocomposite (MC) on alterations of the phenolic profile of strawberry plants in the course of development under in vitro, ex vitro, and in vivo conditions. Aqueous ethanol extracts of aboveground parts of in vitro–derived plants (Fragaria × ananassa cv. ‘Solnechnaya polyanka’) were subjected to HPLC. Nineteen individual phenolic compounds (hydroxybenzoic and hydroxycinnamic acids, catechins, ellagic acid derivatives, and flavonol glycosides) were quantified. The results revealed phenolic profiles specific to each studied stage and significant transformations of the profiles by the MC. It induced strong upregulation of hydroxycinnamic acid during in vitro rooting and of catechins and hydroxybenzoic acids during ex vitro acclimation. At ex vitro and in vivo stages, the emergence of quercetin glycosides and ellagitannins was registered, and the MC elevated their levels during ex vitro acclimation and field growth. Principal component analysis confirmed the significant effect of the MC on the phenolic profile at all stages, and this effect was the strongest during ex vitro acclimation. The results are consistent with previous reports on the modification of phenolic profiles of plants by silicon-derived biostimulants.

“…Our previous studies about the effect of silicon chelates on in-vitro-derived strawberry plants have revealed improved growth and a contribution to changes in physiological characteristics. The physiological role of silicon chelates is thought to decrease contents of hydrogen peroxide and abscisic acid (ABA) and to promote activities of enzymatic antioxidants in the leaves, thereby mediating growth and the development of strawberry plants both under in vitro and ex vitro conditions [ 22 , 23 ]. These results lead us to the hypothesis that silicon chelates can similarly modulate the adaptability of strawberry microclones in vivo.…”

The purpose was to assess the effects of a biostimulant based on silicon chelates in terms of alleviation of the impact of in vivo conditions on strawberry (Fragaria × ananassa cv. ‘Solnechnaya polyanka’) in-vitro-derived plants. As a source of silicon chelates, a mechanocomposite (MC) obtained through mechanochemical processing of rice husks and green tea was used. Root treatment of plants with 0.3 g L−1 of MC dissolved in tap water was performed at 2 weeks after planting. Control plants were watered with tap water. The greatest shoot height, number of roots per plant, root length, number of stolons per plant, daughter ramets per stolon, relative water content, cuticle thickness, and root and shoot biomasses were achieved with the MC supplementation. The improved parameters were associated with a higher silicon content of roots and shoots of the MC-treated plants. Leaf concentrations of hydrogen peroxide and abscisic acid were reduced by the MC. This effect was accompanied by enhanced activity of superoxide dismutase and catalase. The phenolic profile showed upregulation of p-hydroxybenzoic acid, vanillic acid, gallic acid, syringic acid, and ellagic acid derivative 2, while kaempferol rutinoside and catechins were downregulated. Thus, silicon chelates improve growth and trigger the physiological processes that enhance free-radical-scavenging activity in strawberry plants in vivo.
