Russian dandelion, Taraxacum kok-saghyz L.E.Rodin, is an important alternative source of natural rubber. Thus, it is critical to identify the best season for natural rubber production and harvesting for this species. In this study, T. kok-saghyz was grown in experimental fields in Korea to check the variation in rubber content with the change in the season. Studies using T. kok-saghyz plants indicate that spring and autumn are the best seasons for rubber accumulation. For several reasons, our study suggests that planting in autumn and harvesting in late spring is the best strategy for economic cultivation in Korea. Our data will be useful for future commercialization of rubber production from T. kok-saghyz because time will be saved if the plant is grown and harvested in the optimum season.
