ABSTRACT: This study aimed to estimate the effect of spraying
of okra plants, Abelmoschus esculentus (L.) with GA3 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 GA3 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.
