Changes in Growth Parameters, Oil Yield, Fatty Acid Composition and Mineral Content of Two Safflower (carthamus Tinctorius L.) Genotypes in Response to Water Stress
Year: 2020
Type: article
Abstract: The present study was designed to investigate the effects of water stress on growth and development parameters, oil yield coupled with their fatty acid composition as well as mineral content of two safflower genotypes including Remzibey-05 and Gokturk.Accordingly, significant differences regarding plant length, branch number per plant, capsule number per plant, capsule seed number, 1000seed weight and seed yield per pot were assessed.However, first branch length did not exhibit significant differences between genotypes in response to the treatments.Furthermore, Oil yield was not significantly affected by severe water stress for Remzibey-05 even a 1.60% increase was observed under severe water stress but the yield was significantly increased by 2.37% in Gokturk.In terms of oil composition unsaturation degree, UFA/SFA significantly increased with stress for both genotypes.Concerning mineral content; Remzibey -05 genotype had the highest value of K and Na whereas Gokturk genotype had the highest values of Mg, Fe, Cu and Zn.Finally, the experimental groups were discriminated and identified using PCA and heatmap visualization.
