“…These results are congruent with the results of Mozafari et al [27] which reported the significant effect of iron nanoparticles (FeNPs) and salicylic acid (SA) on in vitro strawberry plants under various concentrations of drought stress. Similar results were obtained in two different studies investigating the effects of FeNPs on strawberry plants grown in vitro under salt [54] and drought stress [30]. In both studies, it is reported that the application of FeNPs under stress conditions can reduce the negative effects of stress.…”

“…This research involved the NaSiO 2 effect on in vitro strawberry growth under various levels of PEG-induced drought stress. It has been reported in various previous studies that the application of different nanoparticles to strawberry plants in in vitro and ex vitro conditions has significant effects on plant growth, crop quality, and yield, and also reduces the effect of abiotic stress factors [7,10,27,30,54,55]. One of the most important signs observed in plants exposed to abiotic stress is growth inhibition [20].…”

“…In recent years, various exogenous applications of organic solutions or some NPs that allow the increase of plant tolerance to abiotic stress conditions have attracted attention [3,8,10,11,[27][28][29]. Some nanoparticle applications, which have a less harmful environmental impact compared to many conventional products, are known to have the potential to increase tolerance to drought [10,27,30,31]. External applications of nanoparticles (NPs) contribute to strong root tissue formation, regulation of antioxidant enzyme activity, and cellular water balance [7,27,30,32,33].…”

The aim of the study is to determine the effectiveness of nano-silicon dioxide (NaSiO2) application on the tolerance of strawberry plants exposed to drought stress under in vitro conditions. Drought stress was induced with polyethylene glycol (PEG-6000). In the experiment, the effects of PEG 6000 concentrations (0, 4, 8%) and NaSiO2 concentrations (0, 50, 100 mg L−1) on in vitro strawberry plants were determined. Plants treated with PEG 6000 showed reduced vegetative growth parameters, but this decrease was reduced with NaSiO2 application. The addition of NaSiO2 enhanced shoot and leaf growth, SPAD index, and the leaf relative water content (LRWC) of in vitro strawberry plants. NaSiO2 at 50 mg L−1 induced the maximum shoot and root fresh weight (1.20 g, 1.24 g, respectively) and length (40.09 mm, 34.26 mm, respectively), leaves number (16.67 pieces/plant) and SPAD index 53.57 among 4% and 8% PEG applications. When the superoxide dismutase (SOD) and catalase (CAT) activities were examined, the results showed that the application of NaSiO2 enhanced drought stress tolerance by promoting certain antioxidant responses by increasing SOD and CAT activities under drought stress. Our results suggest that the application of NaSiO2 can help maintain the devastating impact of drought stress and markedly enhance all the examined parameters in the Albion strawberry cultivar under in vitro conditions.

“…In our study, the lowest concentration of PEG (5%) in the MS medium caused a significant reduction in the weight of wild strawberry microshoots to 0.12 g, which was 2.5 times lower than in control microshoots grown on the MS medium with 3% sucrose (Table 1). According to Yosefi et al (2022), PEGinduced water stress negatively affected shoot fresh and dry weight and physiological and biochemical traits. However, an increase in the PEG amount in the growth medium to 12% resulted in larger microshoots (0.44 g).…”

The goal of this research was to evaluate the effect of light, temperature, sucrose and PEG on the growth of Fragaria vesca in vitro and the expression of regulatory Myb10, WD40 and enzyme-coding genes CHI, CHS, DFR, EGL, F3H and UFGT, which are essential for anthocyanin biosynthesis. We observed plants’ response to osmotic stress, the decrease in growth and microshoot weight. A change in the expression of the investigated genes was evident under the suboptimal concentration of sucrose. The addition of PEG to the medium caused a decrease in microshoot weight and gene expression. Blue + red lights of the LED lighting system significantly affected microshoot growth in vitro. Red and blue + red + UV lights slightly reduced microshoot weight and caused a reddish colour of petioles, which indicate increased anthocyanin synthesis. Moreover, most of the studied genes’ expression tended to increase when shoots were exposed to blue, blue + red and blue + red + UV lights. A temperature of 15°C (vs 22°C) significantly reduced the mean fresh weight of microshoots while increasing CHI and CHS gene expression and decreasing WD40 gene expression. Exposure to a higher temperature (30°C) induced the vitrification of microshoots, although the fresh weight did not differ from that of the control. Gene expression also depended on the duration of exposure. In the case of CHS, gene expression remained the same or increased after exposure for 1 week and then decreased after exposure for 4 weeks.

Leucojum aestivum L. is an Amaryllidaceae bulbous plant with two alkaloids that have remarkable medicinal potential: galanthamine and lycorine. Although the presence of galanthamine in L. aestivum has commercial value for the pharmaceutical industry and the effect of water stress (WS) applications on secondary metabolite enhancement is well established in a variety of plants, no studies have been carried out to reveal the effectiveness of WS on this beneficial medicinal plant. Objective of the study was to investigate the effects of eight different WS treatments [Control, waterlogging (WL) condition, and drought stress conditions (water deficiency generated by water deficit irrigation-WDI 25%, 50%, and 75%- and polyethylene glycol-PEG 6000 15%, 30%, and 45%-)] on growth parameters, alkaloid levels (galanthamine and lycorine), non-enzymatic antioxidant activities (total phenol-flavonoid content and free radical scavenging activity), and enzymatic antioxidant activities [superoxide dismutase (SOD) and catalase (CAT)] of L. aestivum in a pot experiment. Based on the findings, maximum increases in growth parameters were obtained with PEG-induced WS treatments. Moderate water deficiency (50% WDI) produced the highest levels of galanthamine and lycorine, total phenol-flavonoid content, and antioxidant capacity, along with moderately elevated CAT activity in the bulbs. All WS treatments resulted in increased CAT activity in the bulbs. It was observed that bulbs had higher SOD and CAT activities under WL conditions had lower fresh weights and were close to control in terms of alkaloid levels, total phenol-flavonoid content, and free radical scavenging activity. When all of the outcomes were taken into account, it can be concluded that moderate water-deficit stress (50% WDI) was regarded as the most effective treatment for increasing the pharmaceutical value of L. aestivum.
