Abstract

Plant growth regulators are organic substances that are synthesized naturally within the plant, and controlled the physiological events, can be transported from where they are formed to other parts of the plants, and can show their effects even at very low concentrations. In this study, it was aimed to determine the effect of different doses of plant growth regulators in different growth stages on oil content and fatty acid compositions of peanut (Arachis hypogaea L.). A total of twelve different treatments were preferred with different chemicals such as gibberallic acid (GA3), mepiquat-chloride (MC), and seaweed (SW) in different growth stages (beginning bloom (BB), full bloom (FB) and beginning bloom + full bloom (BB+FB)). The highest oil content was obtained in MCFB200 (55.46%) treatment, while the lowest was obtained in GA3BB20 (45.44%) treatment. Oleic acid ratio varied from 50.33% to 59.25%, and all treatments were higher than that of the control group. The highest and lowest linoleic acid ratios were observed in SWBBFB100 (26.72%) and GA3FB10 (19.52%) treatments, respectively. MCFB200 and GA3FB10 treatments could be recommended for the highest oil ratio and the highest oleic acid ratio, respectively.
