Variations in L-ascorbic acid (vitamin C), retinol (vitamin A) and ?-tocopherol (vitamin E) contents were determined by using high-pressure liquid chromatography (HPLC) method. Maraton Broccoli was grown as the plant material of the study and 5 different water deficit levels (80, 60, 40, 20%, and a control treatment with 100%) were applied during 3 different growth stages (early vegetative, late vegetative and flowering periods) of broccoli plants. Results revealed significant variations in L-ascorbic acid (vitamin C), retinol (vitamin A) and ?-tocopherol (vitamin E) contents of broccoli heads with deficit irrigation applications at different growth stages.
