摘要

This study aimed to estimate the effect of spraying of okra plants, Abelmoschus esculentus (L.) with GA_(3) on the quality and oil content of the seeds. For this, the local okra variety was selected and used, which was growing widespread in the coastal region of Syria. This study was carried out in Al-Haffa area, Lattakia governorate, Syria (with 105 MSL elevation) for two seasons 2019-2020. The results showed that the effect of spraying with GA_(3) was more evident in the quality of the seeds as well as oil content at 75 ppm concentration with 68.7 g weight of 1000 seeds and 5.31% seed oil percentage. This study also showed that oil of local okra variety seed was rich in the essential fatty acids namely, linoleic, palmitic, oleic, stearic and linolenic, treatment with 75 ppm concentration of GA3 was more effective in the seed content of essential fatty acids with 42.30%, 32.55%, 9.20%, 6.73% and 5.72%, respectively. Finally, our results were indicated that treatment of okra plants at 75 ppm of GA3 enhanced the quality and oil content of seeds compared to the other concentrations.
