“…This result, along with the other results we report, should be interpreted with care, since the sample size in this study was limited and the study was carried out during a single owering season. However, other studies support our nding such as Scherr and Jamieson (2021) that nd insect pollination improves strawberry fruit weight in an urban context, when fruits were not damaged by pests. Moreover, we found no differences in fruit set or fruit quality between the treatment open to insect pollination and the pollen-saturation treatment, indicating the absence of any pollination de cit.…”

Pollination services provided by a diversity of pollinators are critical in agriculture since they enhance the yield of many crops. However, few studies have assessed pollination services in urban agricultural systems. We performed flower-visitor observations and pollination experiments on strawberries, Fragaria × ananassa, in an urban area of Paris, France, in order to assess the effects of (i) insect-mediated pollination service and (ii) potential pollination deficit on fruit set and fruit quality (size, weight, malformation and seed set). Flower-visitor observations revealed that the pollinator community was solely comprised of unmanaged pollinators, despite the presence of apiaries in the surrounding landscape. Based on the pollination experiments, we found that the pollination service mediated by wild insects improved fruit size as a qualitative value of production, but not fruit set. We also found no evidence for pollination deficit in our urban environment. These results suggest that the local community of wild urban pollinators is able to support strawberry crop production, and thus plays an important role in providing high quality, local and sustainable crops in urban areas.

“…This demonstrates that, despite the relative self-compatibility of strawberries, insect pollinators can support the production of strawberries in our local urban agricultural context. Another study found that insect pollination improves strawberry fruit weight in urban contexts when fruits were not damaged by pests [72]. Moreover, we found no increase in the fruit set or fruit quality from the treatment open to insect pollination compared to the pollen saturation treatments (i.e., flowers open to pollinator visits and cross-pollinated by hand), suggesting the absence of any pollination deficit.…”

Pollination services provided by a diversity of pollinators are critical in agriculture because they enhance the yield of many crops. However, few studies have assessed pollination services in urban agricultural systems. We performed flower–visitor observations and pollination experiments on strawberries (Fragaria × ananassa) in an urban area near Paris, France, in order to assess the effects of (i) insect-mediated pollination service and (ii) potential pollination deficit on fruit set, seed set, and fruit quality (size, weight, and malformation). Flower–visitor observations revealed that the pollinator community solely comprised unmanaged pollinators, despite the presence of beehives in the surrounding landscape. Based on the pollination experiments, we found that the pollination service mediated by wild insects improved the fruit size as a qualitative value of production, but not the fruit set. We also found no evidence of pollination deficit in our urban environment. These results suggest that the local community of wild urban pollinators is able to support strawberry crop production and thus plays an important role in providing high-quality, local, and sustainable crops in urban areas.

“…), which are defined as a functional food source beneficial to human health due to its rich content of antioxidants, polyphenols, fiber, vi-tamins, and many nutritional elements [15][16][17], are the most consumed berry fruit in the world [18]. This herbaceous plant is affected by environmental factors and frequently exposed to abiotic stress [8,19]. In arid and semi-arid areas, problems such as low precipitation, high evaporation, and temperature, negatively affect strawberry cultivation [20,21].…”

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.
