Study on phytochemical and horticultural traits of dog rose (Rosa canina) in natural habitat

Abstract

Dog rose is a wild plant that grows throughout the world particularly in some regions of Iran, as a rich source of antioxidants, vitamins and minerals; it is interested in pharmaceutical and food industries. Thus, its phytochemical and horticultural traits including vitamin C, anthocyanins, antioxidants, flavonoids and total phenols were studied in three habitats -Eshkevarat-Rudsar, Kaleshom-Jirandeh and Rudbar-Kushk valley-at two fruit maturity stages 50% maturity and full maturity. It was found that the interaction between habitat and harvest time was significant for the amount of antioxidant, vitamin C and flavonoid. The highest antioxidant, vitamin C and flavonoid contents were obtained in Rudbar-Kushk valley at 50% maturity, in Eshkevarat-Rudsar at full maturity and in Eshkevarat-Rudsar at 50% maturity, respectively. But, the influence of habitat by harvest stage was not significant on total phenol and anthocyanin content.
