Lysophosphatidylethanolamine (LPE) is a promising natural lysophospholipid which can be employed as a growth regulator for horticultural purposes. The present research was accomplished to investigate the effects of LPE (0 or 10 ppm) on the yield and quality of &ldquo:Savana&rdquo: strawberry plants grown during two consecutive cultivation cycles (I (2020&ndash:2021): II (2021&ndash:2022)). Plants cultivated in year I and treated with LPE revealed the highest total yield (838.3 g plant&minus:1), marketable yield (735.4 g plant&minus:1) and average marketable fruit weight (39.8 g plant&minus:1). Fruits from year II plants treated with LPE had the highest total phenolics concentration (491.4 mg 100 g&minus:1 dw). LPE significantly enhanced strawberry antioxidant activity, firmness, soluble solids content, ascorbic acid and anthocyanins by 5.2%, 7.6%, 15.3%, 13.8% and 19.7%, respectively, compared with the control. Although LPE application significantly reduced fruit dry matter, yellowness and lightness by 7.2%, 30.1% and 14.6%, respectively, it significantly increased, in year II, anthocyanins, discarded production, fruit lightness and dry matter. Overall, our findings also revealed that, even under sub-optimal growing conditions (year II), LPE application increased important productive and qualitative strawberry parameters.
