Abstract

Introduction: To develop the efficient protocol for multiple shoot regeneration of A.esculentus by apical root culture method. Abelmoschus esculentus L., commonly known as okra, is a member of the Malvaceae family, which is widely consumed due to its high nutrient content and potential therapeutic properties. Okra contains various bioactive compounds that exhibit antibacterial properties and may be useful in treating type-2 diabetes, digestive diseases, and liver detoxification. To select the plant for the present and prepare the efficient protocol for the development of multiple shoot regeneration culture method.

Methods: In this study, we developed an efficient protocol for multiple shoot regeneration of A. esculentus using the apical shoot culture method. Mature shoot apex explants of the germinated A. esculentus genotype CoBhH1 were cultured on Murashige and Skoog (MS) medium supplemented with different concentrations of cytokinins (BAP and TDZ) and auxins (IAA and NAA) to determine the optimal conditions for shoot induction.

Results: The highest number of multiple shoots (27.04 shoots) was obtained with 0.8 mg/L TDZ. Excised shoots were cultured on MS medium supplemented with GA3, which induced elongation of the shoots to a maximum of 8-10 cm. Regenerated plantlets were successfully transferred to soil, with a 100% survival rate and no differences in morphology or growth characteristics compared to control plants. Rooting was achieved with 1 mg/L IBA.

Conclusion: This study provides an efficient protocol for multiple shoot regeneration of A. esculentus through apical shoot culture, which has potential applications in plant breeding and genetic engineering.
