“…Further, better pollen germination in strawberry flowers is reported with the application of GA 3 (Paroussi et al, 2002). A major portion of non-marketable fruit in strawberries includes the malformed and underweight fruits (Kirschbaum et al, 2014). The aggregate nature of strawberry fruit requires pollination each and every ovary to form a healthy compact fruit.…”

Background: The South Gujarat hilly part is considered to be a non-traditional area of strawberry cultivation in India. The poor farmers of this region are cultivating strawberries under open field condition. Both, the yield and quality of strawberry fruits of this region are not up-to-the-mark as there in other parts of the country. Hence, a low-cost improved production technology is required to maximize yield as well as improve the quality of strawberry fruits. Method: Uniform runners of strawberry cv. Winter Dawn were grown in open field under paddy straw as bedding material. Foliar spraying of plant growth regulators viz. NAA (50, 75, 100 and 125 mg l-1) and GA3 (50, 75, 100 and 125 mg l-1) were done at 30 and 60 days after planting. The experiment was laid out in randomized block design with control plants receiving no spray treatments and replicated thrice. Result: The plant growth parameters like plant spread, number of leaves, number of crowns, leaf area, length of petiole, number of runners were recorded maximum with the application of 100 mg l-1 GA3. This treatment was also found to be the best in respect of number of flowers, number of fruits, fruit weight, marketable and total fruit yield of strawberry. Strawberry fruits with the highest total soluble solid, ascorbic acid, reducing sugar, non-reducing sugar and total sugar content were recorded in the plants which received 125 mg l-1 NAA. However, the plant growth regulator treatments failed to influence any significant effect on days taken to 50.0% flowering, fruit firmness and acidity content of strawberry fruits.

“…As an extensive crop, it also generates presumably large amounts of residues. Non-marketable fruit (small-sized and misshapen berries, with pest and disease damage or albinism) may reach up to 17% of total yields [ 3 ], and the vegetative parts of the plant (leaves, stems, and roots) are mostly discarded [ 4 ]. Moreover, around 21% of the strawberry fruit production is transformed for manufacturing processed products, yielding additional industrial organic wastes (mostly pulp and press residues) [ 5 ], all of which still contain relevant amounts of bioactive compounds [ 5 , 6 , 7 , 8 ].…”

Strawberry Fragaria x ananassa cv. Festival: A Polyphenol-Based Phytochemical Characterization in Fruit and Leaf Extracts

et al. 2023

Berry fruits are an important dietary source of health-promoting antioxidant polyphenols. Interestingly, berry leaves of diverse species, including strawberries, have shown higher bioactive phytochemical content in the leaves than in the fruit. Moreover, the vegetative part of the plants is usually discarded, representing a presumably large source of underutilized bioactive biomass. In this investigation, the polyphenol profiles of tropical highland strawberry (Fragaria x ananassa cv. Festival) leaves and fruits were compared by high-performance liquid chromatography coupled with a diode array detector (UHPLC-DAD) and mass spectrometry (HPLC-MS). The total polyphenol strawberry leaf extracts exhibited a 122-fold-higher total polyphenol content and 13-fold higher antioxidant activity (ORAC) than strawberry fruits, and they showed evidence of possible photoprotective effects against UV damage in human melanoma cells (SK-MEL-28) and in murine embryo fibroblasts (NIH/3T3), together with promising anti-proliferative activities against the same melanoma cells. Seven polyphenols were confirmed by HPLC-DAD in the leaf extracts, with differences depending on fraction solubility. Moreover, three substituted quercetin derivatives, three substituted kaempferol derivatives, two anthocyanins, and catechin were confirmed in the soluble fraction by HPLC-MS. Given their higher total polyphenol content and bioactive activities, underutilized strawberry Festival leaves are a potential source of apparently abundant biomass with prospective bioactive applications.
