This study was carried out in 2019 to determine the effects of methyl jasmonate (MJ), gibberellic acid (GA3) and naphthalene acetic acid (NAA) applications on fruit yield and essential oil content in anise (Pimpinella anisum L.). Different concentrations of MJ (0, 0.1, 0.5 and 1 mM), GA3 (0, 50, 100 and 150 ppm) and NAA (0, 25, 50 and 100 ppm) were pulverized to the plant during the beginning of the flowering. Phytohormone applications had a statistically significant effect on the parameters examined in the study, and the effects of the applications generally varied depending on the application doses. While GA3 and NAA applications significantly increased the fruit yield and essential oil content compared to the control, high-dose MJ applications generally had a negative effect on all parameters except that the thousand-grain weight. The highest fruit yield was obtained from 100 and 150 ppm GA3 and 25 and 50 ppm NAA applications, while 1 mM MJ applications significantly reduced fruit yield compared to the control. Depending on the applications, the fruit essential oil content varied between 1.94%-2.69% and the essential oil yield varied between 1.42-3.18 L/da. While the highest essential oil yields were obtained from 100 ppm GA3 and 50 ppm NAA applications, 1 mM MJ applications caused a significant decrease in essential oil yield compared to the control.

Anise (Pimpinella anisum L.), is a plant which has an important place in the economic sense in medicinal and aromatic plants. Such as health, food, cosmetics are among the leading materials in the use of many sectors. The production of plant materials obtained from seeds obtained from enduring and strong lines is facilitated with the increasing number of studies. Therefore, the characteristics of the lines from which the seeds come must be demonstrated. In this study, four different anise line (Spain, Egypt, Syria, Turkey) some characteristics of by seed (figure-size, surface area, projection area, average geometric and arithmetic diameter, sphericity, thousand grain weight, average germination percentage and time) It was investigated. At the same time, the film coating was applied to the seeds and the changes in these properties of the seeds were determined. The data obtained were also examined statistically.
