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.

Highlights

Okra, Abelmoschus esculentus (L.), is one of the most popular summer vegetables for the Arab consumer and the most widely distributed locally, it is growing in the most tropical and subtropical regions of the world [1]
This study 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
Due to the nutritional value, medicinal benefits, industrial importance of okra fruits and richness of its seeds in unsaturated fatty acids which are necessary for human health, increased demand for vegetable oils due to the increase in population, search for new sources of vegetable oils production, and effectiveness of growth regulators, especially GA3 in improving vegetative growth and seed indicators of okra, as shown by the other studies, this study aimed to evaluate the effectiveness of spraying with GA3 in improving the quality of okra seeds and increasing their oil content

Summary

Introduction

Abelmoschus esculentus (L.), (family Malvaceae), is one of the most popular summer vegetables for the Arab consumer and the most widely distributed locally, it is growing in the most tropical and subtropical regions of the world [1]. Okra pods can be used for consumption fresh, canned, frozen and dried [2]. These pods are an important food source because they contain many nutrients. In addition to the nutritional value, okra pods have medical and therapeutic benefits represented in their ability in regulating blood sugar levels, reducing of blood cholesterol and toxic substance levels in the liver, as well as treating digestive disorders because they contain many digestive enzymes and a large percent of fibers that facilitate the movement of intestines [4]
