Abstract :The objective of this study was to determine the yield and quality characteristics of golden thistle insert ignore into journalissuearticles values(Scolymus hispanicus L.); harvested at different maturity stages. The trial was arranged in the Randomised Complete Block Design under the ecological conditions of Izmir, Turkey in 2017 and 2018 growing seasons and the plants were harvested from November to August at 10 monthly periods. Root lenght insert ignore into journalissuearticles values(cm);, root yield insert ignore into journalissuearticles values(kg ha-1);, root bark yield insert ignore into journalissuearticles values(kg ha-1);, dry root bark yield insert ignore into journalissuearticles values(kg ha-1);, root collar diameter insert ignore into journalissuearticles values(mm);, root xylem diameter insert ignore into journalissuearticles values(mm);, cortex thickness insert ignore into journalissuearticles values(mm);, taraxasterol rate insert ignore into journalissuearticles values(%); taraxasterol acetate rate insert ignore into journalissuearticles values(%); were determined. The highest root and root cortex yields were obtained from the plants harvested in july, the average of two years as 19770.64 kg ha-1 and 6480.65 kg ha-1, respectively. The highest taraxasterol and taraxasterol acetate rates were obtained in May harvest as 0.042% and 0.015% in two years respectively.
