Abstract

The study was conducted to determine the physiological maturity stage of the F1 hybrid cucumber cultivar Amata 765 cultivated at An Huu commune, Dong Thap province, thereby
providing a scientific basis for harvesting to ensure optimal fruit quality. Physiological and biochemical methods were employed to analyze changes in selected parameters - including
fruit length, diameter, reducing sugar content, and vitamin C content - during fruit growth and development from fruit set to maturity. Results revealed that day c post-pollination
represents the ideal stage for cucumber fruit development and quality, at which fruit dimensions approached maximum values (length a cm, diameter b cm), while vitamin C and
reducing sugar contents reached peak levels before exhibiting a slight decline thereafter. Consequently, harvesting at this precise timing is essential to maximize both yield and
nutritional value of the fruit.
