Abstract

The research was conducted to determine the ripening time of the fruit, this is the scientific basis for better harvesting and preservation of the fruit. Using the methods of physiological, biochemical research and analysis of changes in some physiological and biochemical parameters according to the growth and development of cucumber from formation to maturity showed that the length, diameter reached almost maximum size at day 11 after anthesis. The content of chlorophyll in cucumber peel reached its highest value at day 8 and then decreased. The content of carotenoids was low in fruit formation and then increased until it ripens. The vitamin C content and reducing sugar content increased continuously and reached the maximum level day 11 and then decreased slightly. The starch content, total organic acid content and tannin content reached the maximum level when the fruit was 9 days old and then gradually decreased. The pectin content increased from the fruit formation until fruit ripening. Through this study, we found that the cucumber fruit should be harvested at day 11 after anthesis to ensure the nutritional value of the fruit during storage.
