THE EFFECT OF DIFFERENT HARVEST DATES ON THE YIELD AND QUALITY OF THE GOLDEN THISTLE (Scolymus hispanicus L.)
The objective of this study was to determine the yield and quality characteristics of golden thistle (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 (cm), root yield (kg ha-1), root
bark yield (kg ha-1), dry root bark yield (kg ha-1), root collar diameter (mm), root xylem diameter (mm), cortex
thickness (mm), taraxasterol rate (%) taraxasterol acetate rate (%) 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.
