Abstract :
Strawberry has become a popular fruit for production in controlled environments due to its high economic and nutritional value. LED lamps are an innovative tool to accurately regulate lighting conditions in the greenhouse. The aim of this study was to examine the effects of different LED lamp spectra on some qualitative characteristics of strawberry cv Camarosa fruit grown in soilless culture. Six different LED lamp spectra, including red, blue, 75% red-25% blue, 25% red-75% blue, 50% red-50% blue, and white, were employed for this purpose. The control treatment was based on the daylight condition. Fruits soluble carbohydrates, titratable acidity, pH, fruit firmness, total soluble solids, phenol, flavonoids, anthocyanins, antioxidant capacity, and vitamin C were examined. The mean comparison revealed that exposure to LED lamps in soilless conditions had a positive impact on the total soluble solids, phenol, anthocyanins, vitamin C, and soluble carbohydrate contents of the fruit at a significance level of 1%. It can be concluded that the use of LEDs can effectively be utilized to enhance the quality characteristics of the Camarosa strawberry under greenhouse conditions.
